[0025] Heat-not-burn (HNB) devices, as a new type of smoking product, heat cigarettes at low temperatures to release tobacco flavor and smoke, rather than burning them. This reduces the production of harmful substances such as tar and carbon monoxide. Researchers have conducted field tests on existing HNB devices and found that insufficient and uneven heating prevents the complete evaporation of the tobacco oil, potentially allowing some oil to leak into the device. This oil, accumulated inside the device, not only produces an unpleasant odor but is also difficult to clean. It can also cause malfunctions, heating failures, and inability to count, leading to premature failure of the device.
[0026] The utility model provides a heating component and a heat-not-burn smoking device, aiming to solve the technical problem that the heat-not-burn smoking device cannot be used normally due to oil leakage into the smoking device.
[0027] See also Figures 1 to 3 In one embodiment of the present invention, the heating component includes a tube sleeve 100, a tube body 200, a top shell 300 and a bottom shell 400. The tube body 200 is arranged in the tube sleeve 100. The tube body 200 has a accommodating cavity 210 for accommodating cigarettes. The top shell 300 and the bottom shell 400 are respectively arranged at both ends of the tube body 200 and are both connected to the tube sleeve 100. The tube body 200, the tube sleeve 100 and the top shell 300 are enclosed to form a first sealed space 310, and the tube body 200, the tube sleeve 100 and the bottom shell 400 are enclosed to form a second sealed space 410. The first sealed space 310 and the second sealed space 410 are both provided with sealing members 311.
[0028] The technical solution of the present invention prevents tobacco oil from leaking into the interior of the heat-not-burn device by providing a seal 311 in the first sealed space 310 between the tube body 200, the tube sleeve 100, and the top shell 300, as well as in the second sealed space between the tube body 200, the tube sleeve 100, and the bottom shell 400, thereby ensuring the normal use of the heat-not-burn device. In this embodiment, the tube body 200 has a receiving cavity 210 for receiving cigarettes; the tube body 200 is disposed within the tube sleeve 100, that is, the tube sleeve 100 is sleeved on the tube body 200, and the tube sleeve 100 acts as an insulator, preventing the heat of the receiving cavity 210 from escaping; the top shell 300 and the bottom shell 400 are respectively disposed at both ends of the tube body 200 and are both connected to the tube sleeve 100 to secure the tube body 200. The tube body 200, the tube sleeve 100, and the top shell 300 enclose a first sealed space 310, and the tube body 200, the tube sleeve 100, and the bottom shell 400 enclose a second sealed space 410. The seals 311 disposed in the first sealed space 310 and the second sealed space 410 can perform a sealing function to prevent the tobacco oil generated by insufficient or uneven heating of the cigarette from leaking into the interior of the heat-not-burn device, thereby preventing damage to the heat-not-burn device. Specifically, during use, the cigarette is first placed in the accommodating cavity 210. Then, by heating the cigarette contained in the tube body 200, the cigarette can emit smoke without igniting the cigarette. The user can inhale the smoke emitted by the cigarette through the airway of the heat-not-burn device. The tobacco oil generated by insufficient or uneven burning of the cigarette is blocked by the seals 311 disposed in the first sealed space 310 and the second sealed space 410, and thus cannot leak into the interior of the heat-not-burn device. The heating unit 600 is provided with a seal 311 to block the leakage channel of the tobacco oil, preventing the tobacco oil from leaking into the heat-not-burn smoking device, ensuring the normal use of the heat-not-burn smoking device. At the same time, it can also prevent the heat-not-burn smoking device from premature damage and extend the service life of the heat-not-burn smoking device. The heating unit 600 is applicable to the technical fields of heat-not-burn smoking devices, smoking supplies, etc.
[0029] It should be noted that the first sealed space 310 is formed by the tube body 200, the tube sleeve 100, and the top shell 300, while the second sealed space 410 is formed by the tube body 200, the tube sleeve 100, and the bottom shell 400. Taking the first sealed space 310 as an example, a seal 311 is disposed in the first sealed space 310, that is, the seal 311 is disposed in the space formed by the tube body 200, the tube sleeve 100, and the top shell 300. The tube body 200, the tube sleeve 100, and the top shell 300 all abut against the seal 311. As a result, the seal 311 can simultaneously block the gaps between the tube body 200 and the tube sleeve 100, the tube body 200 and the top shell 300, and the tube sleeve 100 and the top shell 300, thereby isolating the interior of the heat-not-burn smoking device from the outside world and preventing tobacco oil from leaking into the interior of the heat-not-burn smoking device. In this embodiment, the top shell 300 and the bottom shell 400 are respectively placed against the ends of the tube body 200, thereby fixing the tube body 200. The top shell 300 and the bottom shell 400 are both fixed to the tube sleeve 100 by bolts, which can reduce the difficulty of installing the top shell 300 and the bottom shell 400, thereby reducing the difficulty of assembling the heating component.
[0030] In one embodiment of the present invention, the seal 311 is a high-temperature resistant member. Specifically, while the heat-not-burn smoking device does not ignite the cigarette during use, it still heats the cigarette to approximately 350°C, allowing the cigarette to emit smoke. Therefore, using a high-temperature resistant material to make the seal 311 can improve the seal's high-temperature resistance and thereby ensure its sealing effectiveness. In one specific embodiment, the seal 311 can be made of a silicone seal ring with a high-temperature resistance of 200°C to 300°C.
[0031] See also Figure 2 and Figure 3 In one embodiment of the present invention, a heat insulating member 110 is provided between the tube body 200 and the tube sleeve 100. In this embodiment, the heat insulating member 110 plays the role of heat insulation and heat preservation, which can prevent the heat temperature of the accommodating cavity 210 from leaking out. Specifically, the tube sleeve 100 and the heat insulating member 110 both have the functions of heat insulation and heat preservation. The tube sleeve 100 and the heat insulating member 110 are used together for secondary heat preservation, which can improve the heat preservation effect of the heating unit 600 and prevent the heat temperature of the accommodating cavity 210 from leaking out. In a specific embodiment, the heat insulating member 110 can be an annular aerogel, and the aerogel can be formed by surrounding a plurality of aerogel units. In a more specific embodiment, the heat insulating member 110 is formed by surrounding two semicircular aerogel units.
[0032] See also Figure 1 and Figure 3In one embodiment of the present invention, the top shell 300 is provided with an opening 320 at a position corresponding to the accommodating chamber 210, and the bottom shell 400 is provided with a smoke inlet chamber 420 connected to the accommodating chamber 210; specifically, when in use, the cigarette passes through the opening 320 of the top shell 300 and is placed in the accommodating chamber 210, and the smoke inlet chamber 420 is formed with a limiting step that can abut against the cigarette, which can limit the position of the cigarette and thereby limit the insertion depth of the cigarette.
[0033] The heating assembly also includes a detection member 500, which is arranged on the outside of the bottom shell 400, and the detection member 500 is used to detect the temperature of the bottom shell 400 in real time. In this embodiment, the detection member 500 is used to detect the temperature of the smoke inlet chamber 420. Specifically, when a user uses a heat-not-burn smoking device, there is a process of smoking and stopping smoking. When the user smokes, the temperature of the bottom shell 400 will rise. When the user stops smoking, the temperature of the bottom shell 400 will drop. The detection member 500 can detect the temperature of the bottom shell 400 in real time and transmit it to the control device of the heat-not-burn smoking device. The control device can then record the number of puffs based on the number of times the temperature rises and falls; wherein, each time the temperature rises and falls, it represents a puff taken by the user. In a specific embodiment, the detection member 500 can be a temperature sensor.
[0034] See also Figure 2 and Figure 3 In one embodiment of the present invention, a heat conducting member is disposed between the detection member 500 and the bottom housing 400. Specifically, the heat conducting member connects the bottom housing 400 and the detection member 500, enabling heat conduction between the bottom housing 400 and the detection member 500, thereby improving the temperature sensitivity of the detection member 500. In a specific embodiment, the heat conducting member can be formed by filling a thermally conductive gel between the detection member 500 and the bottom housing 400.
[0035] In one embodiment of the present invention, the distance between the detection member 500 and the bottom shell 400 is denoted as a, where 0.2 mm ≤ a ≤ 0.5 mm. Specifically, limiting the distance between the detection member 500 and the bottom shell 400 to between 0.2 and 0.5 mm, i.e., limiting the thickness of the heat-conducting member to a smaller range, enables the detection member 500 to more effectively sense temperature changes in the bottom shell 400. When a user uses a heat-not-burn smoking device, the detection member 500 can more sensitively sense temperature changes caused by the flow of air through the bottom shell 400 and record the number of puffs taken by the user.
[0036] See also Figure 3In one embodiment of the present invention, the heating assembly further comprises a heating unit 600, which is sleeved on the tube body 200 and provided with two conducting ends 610, each of which is used for welding to the nickel wire 700. In this embodiment, the heating unit 600 is energized by the power supply of the heat-not-burn smoking device, so as to heat the cigarette in the accommodating cavity 210. Specifically, by welding the conducting ends 610 to the nickel wire 700, the conduction between the power supply of the heat-not-burn smoking device and the heating unit 600 is achieved, which can save tin and also make the connection between the heat conductor and the nickel wire 700 more reliable. In a specific embodiment, the heating unit 600 can be a thermal film.
[0037] In one embodiment of the present invention, both ends of the tube body 200 are configured to be gradually divergent. Specifically, the gradually divergent design of the ends of the tube body 200 facilitates the placement of cigarettes into the accommodating chamber 210 and prevents them from becoming stuck. In this embodiment, since both ends of the tube body 200 are configured to be gradually divergent, i.e., both ends of the tube body 200 are formed with annular gradually divergent plates, the seals 311 disposed in the first sealed space 310 and the second sealed space 410 respectively abut against the corresponding gradually divergent plates. In other words, the abutment of the seals 311 against the gradually divergent plates ensures the sealing effect of the seals 311.
[0038] In one embodiment of the present invention, the pipe sleeve 100 includes a plurality of sequentially connected splicing units 120; alternatively, the pipe sleeve 100 is an integrally formed part. In this embodiment, the pipe sleeve 100 can be manufactured in a variety of ways, including sequentially connecting a plurality of splicing units 120 by snapping them together, or integrally forming the pipe sleeve 100, such as by injection molding.
[0039] The present invention also proposes a heat-not-burn smoking device, which includes the above-mentioned heating component. The specific structure of the heating component refers to the above-mentioned embodiment. Since the heat-not-burn smoking device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0040] Specifically, the heat-not-burn smoking device further includes a housing and an air tube. The heating assembly is disposed within the housing, and the air tube is disposed within the housing and can extend out of the housing, and the air tube is in communication with the accommodating chamber 210. When using the heat-not-burn smoking device, the user extends the air tube out of the housing and, by sucking on the air tube, inhales the smoke generated by the heated cigarette into the mouth through the smoke inlet chamber 420 and the air tube, completing the smoking process.
[0041] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
