Technical Field

[0001] The present application belongs to the technical field of smoking articles, and more specifically, relates to an airway cleaning cover of a heating cigarette article and a heating cigarette article. Background Art

[0002] As people's health awareness increases, smokers are increasingly aware of the health hazards of smoking traditional cigarettes, which has promoted the development of products such as electronic cigarettes. Heat-not-burn smoking devices or electric heating smoking devices use special cigarettes to heat tobacco and other substances in the cigarettes to produce smoke, giving smokers the taste of smoking real cigarettes.

[0003] When using a heating device for cigarettes, the cigarettes will be heated by the heating element, and residues such as cigarette slag will be produced. In the case of long-term use, the residues will accumulate in the airway, so the airway needs to be cleaned frequently. In the unclean state, a cleaning cover will be set on the end face of the airway to protect the airway.

[0004] At present, airway cleaning covers are generally fixed with hinges or installed on the device in a separate manner. There are two types of separate airway cleaning covers. One is made of silicone or rubber, such as the cleaning cover structure disclosed in patents with application numbers 202020704985.7 and 201820035532.2. If excessive force is applied to this structure, the cleaning cover will be completely pulled out, making it very difficult to reinstall it. The other is made of plastic, which uses a finger twist to rotate 1 / 4 turn to achieve fixation and loosening separation, making disassembly more convenient.

[0005] Among them, the method of rotation fixing and loosening has the following problems: since the cleaning cover is relatively small and round, users often play with it unconsciously, which can easily cause the cleaning cover to loosen and be lost. Utility Model Content

[0006] In view of the technical problem in the prior art that the cleaning cover is easily loosened and lost, the embodiment of the present application aims to provide an airway cleaning cover for a cigarette heating device, which can effectively prevent the cleaning cover from being lost.

[0029] like Figure 1-Figure 6 As shown, a cigarette heating device provided in an embodiment of the present application is now described.

[0030] The heating cigarette device comprises a device body 3 and an airway cleaning cover 1. The device body 3 is an existing conventional structure. An airway is arranged in the device body 3. A mounting hole 31 communicating with the airway is arranged at the bottom of the device body 3. The diameter of the mounting hole 31 is larger than the diameter of the airway. The airway cleaning cover 1 is installed in the mounting hole 31. Specifically, the peripheral wall of the mounting hole 31 is symmetrically provided with at least two card slots 32. The card slot 32 is L-shaped. The airway cleaning cover 1 comprises a circular body 11. The peripheral surface of the circular body 11 is symmetrically provided with a buckle 12. The buckle 12 is rotatably matched and fixed with the card slot 32, so that the airway cleaning cover 1 is fixed to the mounting hole 31. When removing, it can be rotated in the opposite direction.

[0031] When the airway cleaning cover 1 is assembled in the mounting hole 31, the end surface height of the circular body 11 is flush with or lower than the end surface of the device body 3. In this way, when the user holds the device body 3, the airway cleaning cover 1 will not be touched, and the airway cleaning cover 1 will not be loosened or lost when playing with the device body 3.

[0032] In this embodiment, when a user purchases the heating cigarette device, a cleaning brush 2 is provided for cleaning the airway.

[0033] In order to facilitate the user to remove the airway cleaning cover 1, a limiting groove 13 is provided on one end face of the circular body 11, and a protrusion 21 is provided on the end face of the handheld part of the cleaning brush 2. The protrusion 21 can be inserted into the limiting groove 13. When the user rotates the cleaning brush 2, the airway cleaning cover 1 can be driven to rotate, thereby realizing the separation or clamping fixation of the buckle 12 and the slot 32. In order to remove the airway cleaning cover 1 from the mounting hole 31, a first magnetic attraction member 14 is provided in the circular body 11, and a second magnetic attraction member 22 attracted to the first magnetic attraction member 14 is provided on the cleaning brush 2. When the buckle 12 is separated from the slot 32, the first magnetic attraction member 14 is magnetically attracted by the second magnetic attraction member 22, so that the airway cleaning cover 1 can be removed from the mounting hole 31 by the cleaning brush 2, and at the same time, the airway cleaning cover 1 is adsorbed on the handheld part of the cleaning brush 2, thereby preventing the airway cleaning cover 1 from being lost; similarly, the airway cleaning cover 1 can be fixed in the mounting hole 31 by the cleaning brush 2.

[0034] In this embodiment, the first magnetic member 14 and the second magnetic member 22 are both magnets, and the magnets are preferably permanent magnets. In other embodiments, the first magnetic member 14 is a magnet and the second magnetic member 22 is an iron block; or the first magnetic member 14 is an iron block and the second magnetic member 22 is a magnet. In this embodiment, two first magnetic members 14 and two second magnetic members 22 are provided. When the protrusion 21 is inserted into the limit card slot 32, the first magnetic member 14 and the second magnetic member 22 are attracted to each other in a one-to-one correspondence.

[0035] In this embodiment, the cross section of the limiting groove 13 is rectangular, square or oval. Of course, it can also be other special-shaped grooves, which ensures that the protrusion 21 can drive the airway cleaning cover 1 to rotate through the limiting groove 13.

[0036] In this embodiment, the end surface of the airway cleaning cover 1 can be provided with an arrow indicating tightening or loosening. A through hole 15 is provided at the center of the limiting groove 13, and the through hole 15 is connected to the airway, so as to ensure that the airway can still take in air normally after the airway cleaning cover 1 is installed.

[0037] In this embodiment, a ring groove 16 is provided on the circumferential surface of the circular body 11, and a rubber ring 17 is provided in the ring groove 16. The rubber ring 17 can play a sealing role on the one hand, and on the other hand, it can increase the friction force when the airway cleaning cover 1 rotates, ensuring that the airway cleaning cover 1 can only rotate with the help of the cleaning brush 2. At the same time, it is also necessary to ensure that the airway cleaning cover 1 can be magnetically sucked out by the cleaning brush 2.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
