[0004] 2. Due to the high temperature, the tobacco and ash burning in the pipe are difficult or impossible to compress.

[0005] 3. The ash produced after burning tobacco is easy to fall off, which is not environmentally friendly.

[0006] 4. If the pipe goes out while the user is smoking, it is inconvenient and difficult to relight it with a match or lighter, and the ash is also easy to fall off. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this invention is to provide an ignition suction device with a movable cover, which enables automatic ignition and makes ignition more convenient.

[0008] Another objective of this invention is to provide an ignition and suction device with a movable cover, which can conveniently hold the tobacco filling in the beaker, prevent the tobacco filling from overflowing, and is more environmentally friendly.

[0009] Another objective of this invention is to provide an ignition and suction device with a movable cover, wherein the heating element can move up and down with the pipe cover, making it easy to adjust the ignition position of the heating element.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows:

The pipe lid covers the mouth of the beaker and is movably connected to the pipe shell. The heating element is fixedly connected to the pipe lid. One end of the pipe conductive module is connected to the pipe rod assembly, and the other end is connected to the heating element.

[0017] The above structure allows the heating element to move up and down with the pipe lid, adjusting its ignition position. This ensures successful ignition whether the beaker is full of tobacco or not. Specifically, when the beaker is full of tobacco, the pipe lid can be flipped upwards at a certain angle, leaving it partially closed, which moves the heating element upwards a short distance for ignition. When the beaker is not full of tobacco, the pipe lid can be fully closed for ignition.

[0018] Furthermore, a heat-insulating silicone sealant is provided between the beaker and the pipe conductive module, and the heat-insulating silicone sealant is installed inside the pipe shell.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0047] To achieve the above objectives, the technical solution of this utility model is as follows:

The pipe lid 35 covers the mouth of the beaker 33 and is movably connected to the pipe shell 31. The heating element 32 is fixedly connected to the pipe lid 35. One end of the pipe conductive module 34 is connected to the pipe rod assembly 2, and the other end is connected to the heating element 32.

[0054] In this embodiment, the pipe cover 35 provided on the mouth of the beaker 33 can hold the tobacco filling material inside the beaker 33 and prevent the tobacco filling material from overflowing; at the same time, the pipe cover 35 can also prevent the residue produced after the tobacco filling material burns from falling off, thereby facilitating the cleaning of the residue.

[0055] In addition, the above structure allows the heating element 32 to move up and down with the pipe lid 35, adjusting the ignition position of the heating element 32. This ensures successful ignition whether the beaker 33 is full of tobacco or not. Specifically, when the beaker 33 is full of tobacco, the pipe lid 35 can be flipped upwards at a certain angle, so that the pipe lid 35 is not completely closed, causing the heating element 32 to move upwards a certain distance for ignition. When the beaker 33 is not full of tobacco, the pipe lid 35 can be completely closed for ignition.

The beaker 33 is disposed inside the bottom shell liner 38.

[0058] Furthermore, one end of the outer cover liner 370 is provided with a rotating protrusion 371, and one end of the bottom shell liner 38 is provided with a rotating position 381. The rotating protrusion 371 is rotatably connected to the rotating position 381 via a rotating shaft 39.

The control PCB board 251 and the control button 252 are both set in the installation groove 222, and the control button 252 passes through and is exposed outside the cigarette rod shell 21.

[0064] Furthermore, the tobacco rod conductive module 24 includes a tobacco rod positive electrode 241 and a tobacco rod negative electrode 242, and the pipe conductive module 34 includes a pipe positive electrode 341 and a pipe negative electrode 342. One end of the pipe positive electrode 341 is electrically connected to the heating element 32, and the other end is electrically connected to the tobacco rod positive electrode 241. One end of the pipe negative electrode 342 is electrically connected to the heating element 32, and the other end is electrically connected to the tobacco rod negative electrode 242. The end of the tobacco rod positive electrode 241 facing away from the pipe positive electrode 341 is electrically connected to the control PCB board 251, and the end of the tobacco rod negative electrode 242 facing away from the pipe negative electrode 342 is electrically connected to the control PCB board 251.

[0065] Further, see Figure 6-7 The positive electrode 341 of the pipe is connected to the positive electrode 241 of the pipe rod by contact, and the negative electrode 242 of the pipe rod is connected to the negative electrode 342 of the pipe by thread. While ensuring the electrical connection between the conductive module 24 of the pipe rod and the conductive module 34 of the pipe, the two are detachable, thereby facilitating the assembly, disassembly, and storage of the pipe rod assembly 2 and the pipe assembly 3.

[0066] Furthermore, the conductive module 24 of the cigarette rod also includes a cigarette rod insulator 243. Both the cigarette rod insulator 243 and the cigarette rod negative electrode 242 are tubular structures.

[0067] Furthermore, the pipe conductive module 34 also includes a pipe insulator 343. Both the pipe insulator 343 and the pipe negative electrode 342 are tubular structures. The pipe insulator 343 is sleeved outside the pipe positive electrode 341, and the pipe negative electrode 342 is sleeved outside the pipe insulator 343.

[0068] In this application, both the tobacco rod conductive module 24 and the tobacco pipe conductive module 34 adopt this sleeve-type structure to achieve conductive connection, which can not only ensure the stability of electrical connection, but also save space and reduce the size of the product.

[0069] Further, see Figure 4-5 A first smoke conductor 26 is provided at one end of the airway support 22 near the pipe assembly 3.

The smoke generated during baking inside the beaker 33 can enter the smoke channel 221 through the fourth through hole 361, the third through hole 3411, the second through hole 2411, and the first through hole 262 in sequence. The design of the above structure allows the first smoke conductor 26 and the heat-insulating silicone 36 to not only have supporting and heat-insulating functions, but also to cooperate with the positive electrode 241 of the smoke rod and the positive electrode 341 of the pipe to realize the transmission of smoke between the airway support 22 and the beaker 33. While ensuring normal smoke transmission, the various components can be tightly fitted together, which can reduce the size of the product.
