Description

Technical Field

[0001] This utility model relates to a smoking device, and more particularly to a smoking device with a uniform heating structure. Background Technology

[0002] When heating heated cigarettes, the heating temperature is strictly controlled below 350℃ to reduce the release of harmful substances, reduce odor, and lower the risk of secondhand smoke exposure. This process holds a pivotal position in the tobacco industry.

[0003] The heating methods used in commercially available heated tobacco products, such as IQOS's resistance ceramic plate / needle heating system, which rapidly heats the tobacco cartridge at the bottom of the heater, can easily lead to uneven heating. In contrast, the heating element (metal plate or needle-like body) is directly inserted into the center of the tobacco cartridge, transferring heat from the inside out. Excessive temperature in the central area can cause tobacco carbonization, while the outer areas may be underheated due to slower heat conduction, resulting in a strong initial smoke followed by a weak finish and uneven aroma release. Utility Model Content

[0004] The purpose of this invention is to provide a smoking device with a uniform heating structure to solve the technical problems in the prior art. It can heat the circumference of the tobacco cartridge and achieve a uniform heating effect in conjunction with the central heating needle.

[0005] This utility model provides a smoking device with a uniform heating structure, including a shell, a partition inside the shell, a cigarette insert tube fixed on the top of the partition, four heating needle insertion holes in the middle of the cigarette insert tube, a circumferential heating needle inserted into each of the four heating needle insertion holes, and a drive ring installed on the top of the shell, the drive ring being connected to the four circumferential heating needles through a connector.

[0006] In the aforementioned smoking device with a uniform heating structure, preferably, a circumferential heating needle support platform is provided between the cigarette insert tube and the inner wall of the shell. Four semi-circular grooves are provided on the top surface of the circumferential heating needle support platform. The four semi-circular grooves are coaxial with the four heating needle insertion holes and have the same diameter.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] Embodiments of this utility model: such as Figures 1-5 As shown, a smoking device with a uniform heating structure includes a housing 1, a partition 2 inside the housing 1, a cigarette insert tube 3 fixedly mounted on the top of the partition 2, the cigarette insert tube 3 being coaxially arranged with the partition 2, four heating needle insertion holes 4 being opened in the middle of the cigarette insert tube 3, and a circumferential heating needle 5 being inserted and connected into each of the four heating needle insertion holes 4, and a drive ring 6 being installed on the top of the housing 1, the drive ring 6 being connected to the four circumferential heating needles 5 through a connector.

[0021] A central heating needle 16 is fixed at the top center of the partition 2. A controller 13 and a battery 14 are arranged inside the housing 1 below the partition 2. A switch 15 is provided on the side wall of the housing 1. The battery 14, switch 15, central heating needle 16 and four circumferential heating needles 5 are all electrically connected to the controller 13.

[0022] The four circumferential heating needles 5 work in conjunction with the central heating needle 16 to compensate for the central heating needle's inability to simultaneously heat the exterior of the tobacco cartridge. This ensures the tobacco cartridge is heated evenly, improving smoke quality.

[0023] Specifically, the top of the cigarette insert tube 3 is higher than the top of the housing 1, and the drive ring 6 is sleeved on the cigarette insert tube 3 and can slide along the cigarette insert tube 3. When the drive ring 6 is pressed down, the drive ring 6 pushes the four circumferential heating needles 5 through the connector, so that the four circumferential heating needles 5 move simultaneously towards the direction of the central heating needle 16 and are inserted into the cigarette cartridge.

[0024] Pull the drive ring 6 upwards. The drive ring 6 pulls the four circumferential heating needles 5 through the connector, causing the circumferential heating needles 5 to be pulled out of the cartridge. At this time, the cartridge can be removed.

[0025] The four heating needle insertion holes 4 on the cigarette insert tube 3 are set at the same height and are evenly distributed in the circumferential direction.

[0026] A circumferential heating needle support platform 7 is provided between the cigarette insert tube 3 and the inner wall of the housing 1. Four semi-circular grooves 8 are provided on the top surface of the circumferential heating needle support platform 7. The four semi-circular grooves 8 are coaxial with the four heating needle insertion holes 4 and have the same diameter.

[0027] Eight heating needle limiting plates 9 are installed on the top of the circumferential heating needle support platform 7. Two heating needle limiting plates 9 are provided on each semi-circular groove 8. The circumferential heating needle 5 is located between the semi-circular groove 8 and the heating needle limiting plate 9.

[0028] By setting four semi-circular grooves 8 and eight heating needle limiting plates 9, the circumferential heating needle 5 can only move along the semi-circular grooves 8 without separating from them, ensuring that the circumferential heating needle 5 can smoothly enter and exit the cigarette insert tube 3.

[0029] Furthermore, the connector is a metal guide wire 10, which is made of shape memory alloy. Four guide wire holes 11 are provided inside the side wall of the housing 1. The guide wire holes 11 are composed of an axial section and an arc section. The metal guide wire 10 is inserted into the guide wire hole 11 from the top of the housing 1, extends out of the guide wire hole 11 from the opening of the arc section, and is fixedly connected to the tail end of the circumferential heating needle 5.

[0030] The arc segment of the guide wire hole 11 allows the end of the metal guide wire 10 connected to the circumferential heating needle 5 to form an arc transition, preventing the circumferential heating needle 5 from getting stuck.

[0031] The circumferential heating needle support platform 7 has four elongated holes 12, which are located below and connected to the four semi-circular grooves 8. The four elongated holes 12 are used for wires to pass through. The wires on the circumferential heating needle 5 pass through the elongated holes 12, pass through the circumferential heating needle support platform 7, extend downward, pass through the partition 2, and are electrically connected to the controller 13.

[0032] It should be noted that the battery 14, switch 15, center heating needle 16, circumferential heating needle 5 and controller 13 are all devices with relatively mature existing technology. Specific models can be purchased according to actual needs. Their specific structures will not be described in this embodiment.

[0033] The working principle of this invention is as follows: When inhaling a heated non-combustible cigarette, the cigarette cartridge is inserted into the cigarette insert tube 3. The central heating needle 16 is inserted into the cartridge from the bottom. After the cartridge is in place, the driving ring 6 is pressed down, causing it to move downwards and contact the top of the housing 1. During the downward movement of the driving ring 6, four circumferential heating needles 5 are pushed by four metal guide wires 10. The four circumferential heating needles 5 slide along four semi-circular grooves 8 and enter the cigarette insert tube 3 through the heating needle insertion hole 4, inserting into the cartridge from the side wall. Pressing the switch 15 activates the controller 13, which controls the battery 14 to supply power to the circumferential heating needles 5 and the central heating needle 16. They simultaneously heat the cartridge, ensuring even heating and improving the smoke quality.

[0034] After inhaling, press switch 15. Controller 13 will stop the circumferential heating needle 5 and the central heating needle 16 from operating. Pull the drive ring 6 upwards. The drive ring 6 moves upwards and pulls the circumferential heating needle 5 through the four metal guide wires 10. Under the pulling force, the circumferential heating needle 5 is withdrawn from the cigarette insert 3. At this point, the cigarette cartridge can be pulled out upwards.

[0035] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
