Description

TECHNICAL FIELD

[0001] The patent belongs to the field of heat-not-burn new tobacco products, and particularly relates to a heating smoking set with a clamping device. BACKGROUND

[0002] Traditional cigarettes need to be ignited by an open flame to produce tobacco smoke. With the increasing attention to health, the harm of smoke generated by the burning of cigarettes in the traditional smoking method has gradually been taken seriously. In order to reduce such harm, heat-not-burn cigarette smoking sets have emerged. The heat-not-burn cigarette smoking set is a device for heating a cigarette, which heats the aerosolization area of the cigarette to a specific temperature through energy conversion, and the aerosol generated thereby is provided for consumers to smoke. This method significantly reduces the tar, carbon monoxide and other harmful substances generated in the combustion process, thereby reducing the health risks to smokers and the surrounding population.

[0003] However, during the use of the heat-not-burn cigarette, the consumer sucks the filter end of the cigarette with the mouth. If the filter section of the cigarette is accidentally touched or the force is too strong, the lips may accidentally take the cigarette out of the heating smoking set, which not only affects the consumer experience, but also may cause waste of the cigarette and potential damage to the heat-not-burn cigarette smoking set. The existing cigarette clamping parts are mostly integrally formed, and the radial position of the clamping part is fixed, which is easy to cause excessive deformation or even breakage of the cigarette, and is not suitable for cigarettes of different diameters.

[0004] Therefore, it is necessary to design a clamping device for a heat-not-burn cigarette smoking set to prevent the cigarette from accidentally slipping or moving, so that the heat-not-burn cigarette smoking set provides a certain supporting force to the cigarette during insertion or removal and does not damage the cigarette, thereby providing a safer, more convenient and comfortable user experience. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the patent is to provide a heat-not-burn cigarette smoking set with a clamping device. The clamping part in the clamping device can displace and provide a supporting force to cigarettes of different diameters, so as to achieve the purpose of stably fixing the cigarette in the heating cavity after the cigarette is inserted into the smoking set without damaging the integrity of the cigarette.

[0011] In another embodiment, the clamping part further comprises a base, and the base is made of elastic material and can be circumferentially stretched and contracted.

[0012] Further, a limiting groove is arranged on an outer surface of the support part, and the clamping part is sleeved on the limiting groove, so that the limiting groove limits the clamping part.

[0054] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0055] like Figures 1-3 According to one embodiment of this patent, a heated smoking device with a clamping device includes: a receiving cavity, a clamping device, and a heating device; the receiving cavity is used to receive a cigarette 100; the clamping device is disposed outside the receiving cavity and is used to clamp the cigarette 100, the clamping device includes a support portion 1210 and a clamping portion 1220; the clamping portion 1220 includes at least one clamping protrusion 1224 for clamping the cigarette 100, the clamping portion 1220 is assembled on the support portion 1210 through the clamping protrusion 1224, and the heating device is located at the distal end of the clamping device for heating the cigarette 100 to generate smoke.

[0056] Specifically, as shown in Figure 1 The heating device includes a heating body 300, a connecting mechanism 400, and a control circuit 500. The clamping device and the heating body 300 in the heating device at the distal end of the clamping device jointly form a containing cavity for receiving the cigarette 100. When the cigarette 100 passes through the clamping device to reach the containing cavity, the cigarette atomization segment 130 coincides with the heating body 300 in the heating device, and the heating body 300 is used to heat the cigarette atomization segment 130 to form an atomization area. The connecting mechanism 400 is arranged at the lower part of the heating body 300 and is used to connect the heating body 300 and the control circuit 500 and provide axial support and positioning for the distal end of the cigarette 100. A plurality of air inlet holes 410 are arranged on the connecting mechanism 400, and the control circuit 500 is arranged at the lower part of the connecting mechanism. When the heating appliance is in a working state, the control circuit 500 delivers electric energy to the heating body 300 through a power supply (not shown in the figure) to make the heating body 300 supply power to heat the cigarette 100 close to the heating body 300. The heating body 300 is heated to above the atomization temperature of the cigarette 100, so that smoke is generated. When the consumer smokes, the airflow enters from the air inlet hole 410 and flows along the atomization area from the distal end to the proximal end, sequentially passing through the cigarette support segment 120 and the filter rod segment 110, carrying the smoke out into the consumer's mouth for smoking.

[0057] Specifically, as shown in Figure 2 Figure 3 The clamping device is designed in a split manner and includes a support part 1210 and a clamping part 1220. The support part 1210 is in a cylindrical shape, and a sleeving segment 1211 and an abutting segment 1212 are arranged on the support part 1210. Figures 1-3 The sleeving segment 1211 is closer to the distal end of the cigarette 100 than the abutting segment 1212. Alternatively, the sleeving segment 1211 can be arranged at the proximal end. Alternatively, the abutting segment 1212 can also be arranged at a position in the middle of the sleeving segment 1211. The abutting segment 1212 is provided with at least one support hole 1213 corresponding to the clamping protrusion 1224; the support holes 1213 are arranged at intervals and can be uniformly arranged in a circumferential direction or symmetrically arranged around the center or randomly arranged asymmetrically; the support holes 1213 have the same axial position or different axial positions; the support holes 1213 have no fixed shape, and are preferably rectangular, circular, or rhombic.

[0058] The clamping portion 1220 is directly sleeved outside the supporting portion 1210, and is closer to the distal end of the cigarette 100. Alternatively, the clamping portion 1220 can also be closer to the proximal end of the cigarette 100. The material of the clamping portion 1220 is rigid, and is preferably plastic or alloy material. Specifically, the plastic material can include but is not limited to polycarbonate, ABS material, PP material, PET material, PS material, ASA material or TPE material. The alloy material can include but is not limited to beryllium copper, stainless steel, spring steel, titanium copper, brass or phosphor bronze.

[0059] The clamping portion 1220 preferably includes a ring-shaped base 1221, a groove 1222 and a plurality of elastic components 1223 extending along the axial direction of the clamping portion 1220. The elastic components 1223 are used to provide elastic force to the clamping portion 1220, and are arranged in sequence along the radial direction of the accommodating cavity. The grooves 1222 are respectively located on both sides of the elastic components 1223, and are used to increase the elastic force of the elastic components 1223. At the same time, the design of the grooves 1222 can provide more deformable space for the elastic components 1223. The grooves 1222 can reduce the size of the clamping portion 1220, reduce the use of materials, reduce the rigid impact brought by the elastic components 1223, increase the stability and reliability, and prolong the service life of the clamping portion 1220.

[0060] Preferably, the elastic component 1223 is formed by subtractive manufacturing from the base 1221; the clamping protrusions 1224 protrude from the elastic component 1223 and extend in the axial direction, the clamping protrusions 224 correspond to the support holes 1213 one by one, the clamping protrusions 1224 extend into the support holes 1213 and protrude from the inner wall of the support part 1210. Before the cigarette is inserted, the elastic component 1223 is not deformed, and the clamping protrusions 1224 are in the first position; after the cigarette is inserted, the elastic component 1223 is deformed, and the clamping protrusions 1224 are pressed by the cigarette and can produce a radial displacement to reach the second position, and the maximum radial displacement can be 1 mm; the elastic component 1223 is deformed at the same time to generate pressure on the clamping protrusions 1224, so that it clamps the cigarette. After the cigarette is pulled out, the clamping protrusions 1224 reset. The clamping protrusions 1224 can directly contact the support section 120 of the cigarette, so that the clamping protrusions 1224 can make the diameter of the clamped cigarette 100 shrink, preferably by 0.1-0.5 mm. Preferably, the maximum projection shape of the clamping protrusions 1224 in the support hole 1213 is consistent with the shape of the support hole 1213; preferably, the size of the maximum projection shape of the clamping protrusions 1224 in the support hole 1213 is slightly smaller than that of the support hole 1213; optionally, the shape of the clamping protrusions 1224 is inconsistent with the shape of the support hole 1213, and the support hole 1213 can allow the clamping protrusions 1224 to pass through. Preferably, the clamping protrusions 1224 have a radially inward arc surface that can guide the insertion of the cigarette. Preferably, an elongated slit or an elongated rib extending in the axial direction of the elastic component 1223 is arranged on the arc surface of the clamping protrusions 1224 to increase the friction coefficient between the clamping protrusions 1224 and the cigarette 100, as a more precise guide mechanism to ensure that the clamping protrusions can accurately clamp the cigarette 100 and reduce the risk of damage to the clamping protrusions 1224; more specifically, the clamping part of the clamping protrusions 1224 is the support section 120 of the cigarette, and the elongated slit or the elongated rib on the arc surface of the clamping protrusions 1224 increases the friction between the clamping protrusions 1224 and the support section 120 of the cigarette. The elastic component 1223 is an elastic arm structure that can provide elasticity when the cigarette 100 is inserted into the accommodating cavity, so that the clamping protrusions 1224 retreat, the clamping protrusions 1224 move away from the support part 1210, and the cigarette 100 can be taken out of the accommodating cavity.

[0061] As Figure 4As shown, the working state of the clamping device is that when the cigarette 100 enters the containing cavity from outside, it first passes through the clamping device, the clamping protrusion 1224 of the clamping device exerts pressure on the cigarette 100, so that the cigarette support section 120 is immediately adjacent to the clamping protrusion 1224 of the clamping device, the clamping protrusion 1224 reaches the second position, and the clamping protrusion 1224 has a certain clamping force on the cigarette 100, so that the cigarette 100 is stable in the containing cavity; when the consumer finishes smoking this cigarette 100, the cigarette 100 is directly pulled out; after the cigarette 100 is taken out, the elastic component 1223 can provide a restoring force for the clamping protrusion 1224, so that the clamping protrusion 1224 returns to the first position, i.e., the initial state, after completing the clamping action.

[0062] As another embodiment of the patent, as shown in the drawings, Figures 5-6 As shown, the clamping device is designed in a split manner, and the clamping device includes a support part 2210 and a clamping part 2220. The support part 2210 is in the shape of a cylinder as a whole, and is provided with a sleeving section 2211 and a limiting groove 2212. The sleeving section 2211 is closer to the distal end of the cigarette 100 relative to the limiting groove 2212, and the limiting groove 2212 is provided with at least one support hole 2213 corresponding to the clamping protrusion 2224; the support holes 2213 are arranged at intervals, which can be uniformly arranged in the circumferential direction or symmetrically arranged about the center, or can be asymmetrically and randomly arranged; the support holes 2213 have the same axial position or different axial positions; the support holes 2213 have no fixed shape, and preferably, the support holes 2213 are rectangular, circular or rhombic. The clamping part 2220 includes a base 2221 and a clamping protrusion 2224. The base 2221 is made of elastic material, so that when the cigarette is inserted, the base can be deformed to cause the clamping protrusion to displace radially to reach the second position; after the cigarette is pulled out, the deformation is restored, and the clamping protrusion returns to the first position. The base 2221 is in the shape of a ring as a whole, and is distributed with a plurality of clamping protrusions 2224 arranged at intervals on the inner surface of the base 2221; the clamping protrusions 2224 correspond one-to-one to the support holes 2213, and the clamping protrusions 2224 can be uniformly arranged in the circumferential direction or symmetrically arranged about the center, or can be asymmetrically and randomly arranged; the clamping protrusions 2224 have the same axial position or different axial positions; the clamping protrusions 2224 have no fixed shape, and preferably, the radial cross section of the clamping protrusion 2224 along the base 2221 is semicircular.

[0063] In one embodiment, the base 2221 and the clamping protrusion 2224 are integrally formed, and both the clamping protrusion 2224 and the base 2221 are made of elastic materials, including but not limited to silicone or rubber. In another embodiment, the clamping protrusion 2224 and the base 2221 are integrally formed by two-color injection molding (hereinafter referred to as two-color integral molding). The clamping protrusion 2224 is made of plastic or alloy materials. Plastic materials include but are not limited to polycarbonate, ABS, PP, PET, PS, ASA, or TPE; alloy materials include but are not limited to beryllium copper, stainless steel, spring steel, titanium copper, brass, or phosphor bronze. The base 2221 is made of elastic materials, including but not limited to silicone or rubber.

[0064] The clamping part 2220 is directly sleeved on the outside of the sleeved section 2211 of the support part 2210, preferably fixed to the support part 2210 by the limiting groove 2212. The clamping protrusion 2224 passes through the bracket hole to assemble the clamping part 2220 onto the support part 2210. Due to the elasticity of the base material 2221 of the clamping part 2220, the clamping protrusion 2224 is squeezed into the bracket hole 2213 and protrudes from the inner wall of the support part 2210. The clamping protrusion 2224 directly contacts the cigarette support section 120. Preferably, the surface of the clamping protrusion 2224 is spherical. More preferably, a circular protrusion 2225 is provided on the spherical surface of the clamping protrusion 2224 closer to the proximal end of the cigarette 100 to increase the coefficient of friction between the clamping protrusion 2224 and the cigarette 100. This serves as a more precise guiding mechanism, ensuring that the clamping protrusion can accurately clamp the cigarette 100 and reducing the risk of damage to the clamping protrusion 2224.

[0065] like Figure 7 As shown, the working state of the clamping device is as follows: When the cigarette 100 enters the receiving cavity from the outside, it first passes through the clamping device. The clamping protrusion 2224 of the clamping device has a certain frictional force on the cigarette 100, so that the cigarette support section 120 is close to the clamping protrusion 2224 of the clamping device. The clamping protrusion 2224 undergoes radial displacement to reach the second position. The base 2221 deforms and applies a radially inward force to the clamping protrusion 2224. The clamping protrusion 2224 has a certain clamping force on the cigarette 100, so that the cigarette 100 is firmly placed in the receiving cavity. When the consumer finishes smoking the cigarette 100, the cigarette 100 is directly pulled out, and the clamping protrusion 2224 returns to the first position. When the cigarette 100 is removed, the base 2221 also generates a certain restoring force due to its own elastic material, so that the clamping protrusion 2224 or the base 2221 returns to the initial state after completing the clamping action.

[0066] Therefore, it can be concluded that the heating smoke appliance with clamping device provided in this patent has the following advantages over the prior art:

[0067] 1、The heating cigarette device with clamping device provided by the patent, by setting the supporting part 1210 or 2210, clamping part 1220 or 2220 on the heating cigarette device, so that the cigarette 100 can be stable in the heating cigarette device during insertion into the accommodation cavity or use, avoiding the consumer from being taken out or causing scalding and other safety hazards due to accidental external force when smoking.

[0068] 2、The clamping device can realize stable clamping of the cigarette 100, which can ensure that the cigarette 100 remains in a stable heating state, so that the consumer can feel more uniform and stable tobacco flavor, avoiding waste due to uneven heating of the cigarette 100, thereby improving the consumer experience.

[0069] 3、The clamping device can realize stable clamping of the cigarette 100, preventing accidental damage to the heating cigarette device and prolonging the service life of the heating cigarette device.
