[0037] It should be noted that the self-starting cigarette heating device of the present utility model further includes an infrared detection module. The infrared detection module is used to detect whether a non-combustible cigarette is inserted into the first housing 1. When a non-combustible cigarette is inserted into the first housing 1, the infrared detection module controls the heating component 4 to start. By setting the limit fixing block 31 to be made of light-transmitting glass material, the infrared rays emitted by the infrared detection module can pass through the limit fixing block 31 made of light-transmitting glass material, thereby monitoring whether a non-combustible cigarette is inserted into the first housing 1, which increases the intelligence of the self-starting cigarette heating device of the present utility model.

[0038] In an embodiment of the self-starting cigarette heating device of the present utility model, as Figures 1 to 7 shown, connection holes 21 are provided on both side walls of the upper cover 2. The second fixing block 312 is inserted into the connection holes 21. The connection holes 21 are circular holes, the installation opening 32 is a square structure, the vertical cross-section of the first fixing block 311 is rectangular, and the vertical cross-section of the second fixing block 312 is circular.

[0039] Specifically, there are two connection holes 21 and two installation openings 32, which are respectively provided on the opposite side walls of the upper cover 2.

[0041] In an embodiment of the self-starting cigarette heating device of the present utility model, as Figures 1 to 6 shown, a square fixing sleeve 22 is provided on the outer periphery of the connection hole 21. The width of the square fixing sleeve 22 is greater than the diameter of the connection hole 21 and less than the width of the installation opening 32. The outer peripheral wall of the installation opening 32 abuts against the square fixing sleeve 22. The first fixing block 311 is inserted into the installation opening 32 and the square fixing sleeve 22 and abuts against the square fixing sleeve 22.

[0042] Specifically, the width of the square fixing sleeve 22 is slightly less than the width of the installation opening 32.

[0043] By making the width of the square fixing sleeve 22 greater than the diameter of the connection hole 21 and less than the width of the installation opening 32, making the outer peripheral wall of the installation opening 32 abut against the square fixing sleeve 22, inserting the first fixing block 311 into the installation opening 32 and the square fixing sleeve 22 and abutting against the square fixing sleeve 22, when the first fixing block 311 is inserted into the installation opening 32 and the connection opening, the outer peripheral wall of the first fixing block 311 is squeezed by the square fixing sleeve 22, so that the first fixing block 311 and the square fixing sleeve 22 can be stably fixed.

[0044] In an embodiment of the self - starting cigarette heating device of the present utility model, as Figure 4 shown, the fixing component 3 further includes a limiting boss 33, and the limiting bosses 33 are respectively and evenly spaced on the inner wall of the mounting opening 32.

[0045] In the present utility model, by respectively and evenly spacing the limiting bosses 33 on the inner wall of the mounting opening 32, when the first fixing block 311 is inserted into the mounting opening 32, the limiting bosses 33 have a limiting effect on the first fixing block 311.

[0046] In an embodiment of the self - starting cigarette heating device of the present utility model, as Figure 4 shown, the height of the limiting boss 33 is first gradually increased from the outer edge of the first housing 1 towards the inside of the first housing 1, and then the height of the limiting boss 33 remains unchanged and extends to be flush with the inner wall of the first housing 1.

[0047] In the present utility model, by first gradually increasing the height of the limiting boss 33 from the outer edge of the first housing 1 towards the inside of the first housing 1, and then keeping the height of the limiting boss 33 unchanged and extending to be flush with the inner wall of the first housing 1, when the first fixing block 311 is inserted into the mounting opening 32, the limiting bosses 33 located outside the mounting opening 32 have a buffering effect and a guiding effect on the first fixing block 311, enabling the first fixing block 311 to be smoothly and quickly inserted into the square fixing sleeve 22, ensuring the stability of the connection between the first fixing block 311 and the mounting opening 32 and the square fixing sleeve 22.

[0048] In an embodiment of the self - starting cigarette heating device of the present utility model, as Figure 2 and Figure 7 shown, the heating component 4 includes a second housing 41, a heating part 43 and a heat - conducting part 42. The heating part 43 and the heat - conducting part 42 are both arranged inside the second housing 41. The heating part 43 is used to heat the heat - conducting part 42, and the heat - conducting part 42 is used to heat the non - combustible cigarette to form an aerosol. A groove 44 is arranged outside the second housing 41, and a fixing protrusion 11 is arranged on the inner part of the first housing 1. The fixing protrusion 11 is inserted into the groove 44 and is slidably connected with the groove 44.

[0049] In the present utility model, by arranging both the heating part 43 and the heat - conducting part 42 inside the second housing 41, arranging a groove 44 outside the second housing 41, arranging a fixing protrusion 11 on the inner part of the first housing 1, inserting the fixing protrusion 11 into the groove 44 and being slidably connected with the groove 44, through the cooperation of the fixing protrusion 11 and the groove 44, the stability of the installation of the first housing 1 is further increased, and at the same time, the position of the second housing 41 is limited, avoiding the problem that the second housing 41 and the first housing 1 move relative to each other, resulting in a malfunction.

[0050] In an embodiment of the self-starting cigarette heating device of the present utility model, as Figures 1 to 7 shown, the heating component 4 includes a through hole 23 at the central position of the upper cover 2, and the through hole 23 communicates with the second housing 41; the bottom of the upper cover 2 has a limiting ring 24, and the diameter of the limiting ring 24 is greater than the diameter of the through hole 23.

[0051] The outer peripheral wall of the first end of the second housing 41 is inclined, the first end of the second housing 41 abuts against the bottom of the upper cover 2, and the limiting ring 24 abuts against the outer peripheral wall of the second housing 41.

[0052] Specifically, the non-combustible cigarette is inserted into the first housing 1 and the second housing 41 through the through hole 23 and contacts the heat conducting part 42, and then is heated by the heat conducting part 42.

[0053] The present utility model sets the diameter of the limiting ring 24 to be greater than the diameter of the through hole 23, and makes the outer peripheral wall of the first end of the second housing 41 inclined, so that the first end of the second housing 41 abuts against the bottom of the upper cover 2, and the limiting ring 24 abuts against the outer peripheral wall of the second housing 41, thereby stably matching the first end of the second housing 41 with the upper cover 2, and further ensuring that the second housing 41 and the upper cover 2 can be stably installed in the first housing 1.
