[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0031] As Figures 1 to 4As shown in the figure, the smoking device of the present invention includes a housing 2, a paper cutter 3 for cutting the cigarette paper of a cigarette 1, a feeding component 4 for extracting the tobacco shreds in the cigarette 1, and a heating mechanism 5 for heating the tobacco shreds extracted by the feeding component 4. A passage 21 for accommodating the cigarette 1 is provided on the housing 2. The paper cutter 3 is provided on the inner wall of the passage 21. The feeding component 4 is slidably provided on the housing 2 and can move along the passage 21. The heating mechanism 5 is provided inside the housing 2. By providing the paper cutter 3 in the passage 21, when the cigarette is inserted into the passage 21, the paper cutter 3 can cut the cigarette paper. Then, the feeding component 4 is driven to move to extract the tobacco shreds in the cigarette 1, so that the tobacco shreds fall into the heating mechanism 5. The heating mechanism 5 heats the tobacco shreds, and after generating smoke, it can be smoked (when smoking, the user's mouth contacts the cigarette butt). In this way, when smoking a cigarette, the smoking device can only heat the tobacco shreds, avoiding the generation of a burnt paper smell. After smoking is completed, the user pulls out the cigarette butt, and then the cigarette paper can be pulled out, and the cigarette paper is intact, which is convenient for collection. In this embodiment, the user can manually drive the feeding component 4 to move to extract the tobacco shreds in the cigarette 1. In other embodiments, other electric mechanisms can also be used to drive the feeding component 4 to move.

[0032] As Figure 4 and Figure 5 shown in the figure, the heating mechanism 5 includes a heating part 51 for heating the tobacco shreds and an electric control part. The heating part 51 is provided with a feeding port 511, and the feeding port 511 is communicated with the passage 21. The electric control part is electrically connected to the heating part 51 and can make the heating part 51 generate heat, thereby heating the tobacco shreds in the heating part 51. The outer shape of the housing 2 is in the shape of a "cigar" (a kind of tobacco product), which includes an upper housing 22 and a lower housing 23. The passage 21 is provided on the upper housing 22, and the heating part 51 is located at the top of the lower housing 23. A connecting arm 221 is also provided on the upper housing 22. A sliding groove 231 is provided on the lower housing 23. The sliding groove 231 extends along the axial direction of the passage 21. The connecting arm 221 is slidably provided in the sliding groove 231. After smoking is completed, the user pulls the upper housing 22 to make the connecting arm 221 slide in the sliding groove 231 until the connecting arm 221 is pulled to the top of the sliding groove 231, and then rotates the upper housing 22 to expose the feeding port 511 of the heating part 51, and then pours out the heated tobacco shreds. This structure of the housing 2 can prevent the heated tobacco shreds from contaminating the passage 21, thereby affecting the smoking taste.

[0033] As Figure 3 shown in the figure, the paper cutter 3 is located at the top of the passage 21, and the included angle between the paper cutter 3 and the direction of the cigarette 1 inserted into the passage 21 is 10° to 30°, so that the paper cutter 3 can more easily cut the cigarette paper. In this embodiment, the included angle between the paper cutter 3 and the direction of the cigarette inserted into the passage 21 is preferably 20°. Specifically, there is one paper cutter 3 in total. In other embodiments, multiple paper cutters 3 can also be provided.

[0034] AsFigure 1 , Figure 4 and Figure 6 As shown in Figure 1 , Figure 4 and Figure 6 , the tobacco feeding assembly 4 includes a pushing member 41 and a tobacco feeding member 42, and the tobacco feeding member 42 is connected to the pushing member 41. A first sliding groove 24 extending axially along the channel 21 is formed on the outer shell 2, and the pushing member 41 is slidably disposed in the first sliding groove 24. In use, the user drives the pushing member 41 to move radially along the channel 21, inserts the tobacco feeding member 42 into the cigarette 1, and then drives the pushing member 41 to move along the first sliding groove 24 to drive the tobacco feeding member 42 to move downward and extract the cut tobacco. In this embodiment, the tobacco feeding member 42 is a tobacco feeding plate. A protruding pointed head 421 is provided at the end of the tobacco feeding plate, which can make it easier for the tobacco feeding plate to be inserted into the cigarette 1.

[0035] As Figure 6 shown, the tobacco feeding assembly 4 further includes a fixing member 43 and an elastic member 44. The fixing member 43 is slidably disposed in the channel 21. One end of the elastic member 44 is connected to the fixing member 43, and the other end is connected to the pushing member 41. In use, after the cigarette enters the channel 21, the user drives the pushing member 41 to move radially along the channel 21, causing the elastic member 44 to undergo elastic deformation, and then the tobacco feeding member 42 is inserted into the cigarette 1; then the user drives the pushing member 41 to move downward along the first sliding groove 24 to extract the cut tobacco. As Figure 2 shown, a key 45 is further provided on the pushing member 41, which can facilitate the user to drive the pushing member 41 to move.

[0036] As Figure 7 and Figure 8 shown, the smoking device further includes a tobacco pipe 6. The tobacco pipe 6 is disposed in the channel 21 and is located below the paper cutter 3. The tobacco pipe 6 is provided with a first insertion groove 61 and a second sliding groove 62. The first insertion groove 61 is communicated with the second sliding groove 62 and is located at the top end of the second sliding groove 62. The second sliding groove 62 corresponds to the position of the first sliding groove 24 (i.e., the first sliding groove 24 is communicated with the second sliding groove 62), and the length of the tobacco pipe 6 is slightly shorter than the length of the channel 21. When inserting the cigarette 1, the cigarette 1 is inserted from the top end of the channel 21, and the paper cutter 3 cuts the cigarette paper. Then the cigarette 1 enters the tobacco pipe 6. The user applies a radial thrust along the channel 21 to the pushing member 41, causing the elastic member 44 to undergo elastic deformation, and then the tobacco feeding member 42 passes through the first insertion groove 61 and is inserted into the cigarette 1; then the user drives the pushing member 41 to move downward along the first sliding groove 24 and the second sliding groove 62 to extract the cut tobacco. In this embodiment, the cross-sectional width of the second sliding groove 62 is smaller than the cross-sectional width of the first insertion groove 61. In this way, when the user inserts the tobacco feeding member 42 into the cigarette 1 and then drives the pushing member 41 to move downward, even if no radial thrust along the channel 21 is applied to the pushing member 41, the tobacco feeding member 42 will not pop out from the first sliding groove 24.

[0037] As Figure 4As shown, in order to prevent the leakage of smoke during smoking, the smoking device further includes a first shielding portion 7 for closing the tobacco pipe 6. The first shielding portion 7 is rotatably arranged in the channel 21. Before the heating mechanism 5 heats the tobacco, rotate the first shielding portion 7 to shield the first insertion slot 61 and the second sliding slot 62 (i.e., close the tobacco pipe 6), so that the first sliding slot 24 and the second sliding slot 62 are in a non-connected state. Then heat the tobacco to prevent the smoke from leaking out of the tobacco pipe 6.

[0038] As Figure 4 and 10 shown, the smoking device further includes a second shielding portion 8 for preventing the heated tobacco from leaking out. A plurality of air holes 81 are formed in the second shielding portion 8. The second shielding portion 8 is movably arranged on the heating portion 51. During use, the feeding component 4 extracts the tobacco in the cigarette 1. After the tobacco falls into the heating portion 51, rotate the second shielding portion 8 to shield the feeding port 511. In this way, when the user rotates the entire smoking device, the heated tobacco will not leak out of the heating portion 51.

[0039] As Figure 5 , Figure 9 and Figure 10 shown, the first shielding portion 7 is further provided with a connecting rod 71. The first shielding portion 7 is connected to the second shielding portion 8 through the connecting rod 71. A through hole 82 is formed in the second shielding portion 8, and a convex block 512 cooperating with the through hole 82 is provided on the heating portion 51. The second shielding portion 8 is rotatably arranged on the heating portion 51. During use, the user drives the first shielding portion 7 to rotate, driving the connecting rod 71 to rotate, and further driving the second shielding portion 8 to rotate around the convex block 512 to shield the feeding port 511 of the heating portion 51. After the smoking is completed, the user pulls the upper housing 22 to drive the first shielding portion 7 to move, and further drive the second shielding portion 8 to move, so that the convex block 512 is separated from the through hole 82 of the second shielding portion 8, exposing the feeding port 511, which is convenient for pouring out the heated tobacco. In this way, the second shielding portion 8 rotates synchronously with the first shielding portion 7, without the need to rotate the second shielding portion 8 separately, which is convenient for operation and saves operation steps. In this embodiment, there are two second shielding portions 8 in total, and there are also two connecting rods 71 and convex blocks 512. When the first shielding portion 7 rotates, it drives the two connecting rods 71 to rotate synchronously, and further drives the two second shielding portions 8 to rotate in opposite directions around the convex block 512.

[0040] Refer to Figure 1 , Figure 6 , Figure 8 and Figure 9As shown, a limiting groove 431 is provided on the fixing member 43, a limiting block 72 matching the limiting groove 431 is provided on the first shielding portion 7, and the fixing member 43 is slidably arranged on the first shielding portion 7. A rotating groove 25 is provided on the upper housing 22, the rotating groove 25 communicates with the first sliding groove 24 and is located at the bottom end of the first sliding groove 24. A first notch 63 corresponding to the position of the rotating groove 25 is provided on the smoke pipe 6, the first notch 63 communicates with the second sliding groove 62 and is located at the bottom end of the second sliding groove 62. During use, when the material pushing member 40 moves to the bottom end of the first sliding groove 24, the user releases the first pushing member 41 to enable the elastic member 44 to return to its original state, and the material pushing member 40 pops out of the smoke pipe 6 from the first notch 63; then the user drives the pushing member 41 to rotate, so that the pushing member 41 slides into the rotating groove 25, drives the fixing member 43 to rotate, and further drives the first shielding portion 7 and the second shielding portion 8 to rotate synchronously, closes the smoke pipe 6, and shields the feeding port 511. The structure is simple and convenient to operate.

[0041] As Figure 7 and Figure 10 shown, the first shielding portion 7 is tubular, and the smoke pipe 6 is located inside the first shielding portion 7. A second insertion groove 73, a third sliding groove 74, and a second notch 75 are formed on the first shielding portion 7. Both the second insertion groove 73 and the second notch 75 communicate with the third sliding groove 74 and are respectively located at both ends of the third sliding groove 74. The second insertion groove 73 corresponds to the first insertion groove 61, the third sliding groove 74 corresponds to the first sliding groove 24, and the second notch 75 corresponds to the rotating groove 25. The fixing member 43 is annular, the limiting groove 431 is arranged on the inner side of the fixing member 43, and the fixing member 43 is sleeved on the first shielding portion 7. In this embodiment, there are two groups of limiting blocks 72, each group includes two limiting blocks 72, and the two groups are symmetrically arranged on the first shielding portion 7.

[0042] When using this smoking device, the user inserts the cigarette 1 from the top of the channel 21, and the paper cutter 3 cuts the cigarette paper of the cigarette 1 (after insertion, the cigarette 1 is located inside the cigarette tube 6). The user drives the button 45 to move radially along the channel 21, driving the pusher 41 to move, causing the elastic member 44 to undergo elastic deformation, and then driving the material pusher 42 to pass through the second insertion slot 73 and the first insertion slot 61 and insert into the cigarette 1. Then, the user drives the button 45 to move along the first sliding groove 24, driving the fixing member 43 to move along the first shielding portion 7, and at the same time driving the pusher 41 to move along the second sliding groove 62 and the third sliding groove 74, to pick out the tobacco in the cigarette 1, so that the tobacco falls into the heating portion 51. When the button 45 moves to the bottom end of the first sliding groove 24 (at this time, all the tobacco has fallen into the heating portion 51), the user releases the button 45, causing the elastic member 44 to return to its original state, and then driving the material pusher 42 to withdraw from the first notch 63 and the second notch 75 in sequence and pop out from the cigarette tube 6. The user rotates the button 45 so that the button 45 slides into the rotating groove 25, driving the pusher 41 to rotate, and then driving the fixing member 43 to rotate, and the first shielding portion 7 rotates accordingly to close the cigarette tube 6 (the first shielding portion 7 shields the first insertion slot 61, the second sliding groove 62, and the first notch 63). When the first shielding portion 7 rotates, it drives the connecting rod 71 to rotate, and then drives the second shielding portion 8 to rotate around the convex block 512 to shield the feeding port 511 of the heating portion 51. At this time, the user turns on the electronic control unit to heat the tobacco in the heating portion 51, and after generating smoke, it can be sucked. After the smoking is completed, when the cigarette filter and the cigarette paper are pulled out, the user pulls the upper housing 22, causing the connecting arm 221 to move along the sliding groove 231, driving the first shielding portion 7 to move, and then driving the second shielding portion 8 to move, so that the convex block 512 disengages from the through hole 82. When the upper housing 22 is pulled to the top end of the sliding groove 231, the upper housing 22 is rotated to expose the feeding port 511 of the heating portion 51, and the heated tobacco is poured out.

[0043] After that, the user rotates and pushes the upper housing 22 so that the connecting arm 221 is located at the bottom end of the sliding groove 231. Then the user turns the button 45 from the rotating groove 25 into the first sliding groove 24, thereby driving the first shielding portion 7 to rotate, making the second sliding groove 62 communicate with the first sliding groove 24. The user drives the button 45 to move radially, causing the elastic member 44 to undergo elastic deformation, driving the material pusher 42 to pass through the second notch 75 and the first notch 63 and insert into the cigarette tube 6. Then the user drives the button 45 to move upward along the first sliding groove 24, driving the material pusher 42 to move. When it moves to the top end of the first sliding groove 24, the user releases the button 45, and the elastic member 44 returns to its original state, thereby driving the material pusher 42 to withdraw from the first insertion slot 61 and the second insertion slot 73 in sequence and pop out from the cigarette tube 6 to prepare for the next smoking.

[0044] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
