In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] Integrated stoves are usually installed in the middle of the cabinet. There is a certain distance between the integrated stove and the public flue, so a smoke pipe is required to connect the integrated stove's air outlet and the check valve of the public flue. If there is a gap at the connection between the two ends of the smoke pipe, after the integrated stove has been working for a period of time, oil will flow into the cabinet along the gap, affecting hygiene and being extremely difficult to clean.

[0047] In the prior art, sealing rings are usually used to seal both ends of the smoke pipe. Although the use of sealing rings can achieve an ideal sealing effect, the specifications of the sealing rings need to be adjusted according to the specifications of the smoke pipe, and the sealing rings need to be molded. In the production process of the smoke pipe, if different specifications of sealing rings are molded according to different specifications of smoke pipes, the production cost will be greatly increased.

[0048] In order to solve the above problems, Figure 1 to Figure 5As shown, this embodiment provides a cigarette pipe sealing device 1000 . The smoke pipe sealing device 1000 includes a smoke pipe 100, an air outlet seat, a check valve 300 and a sealing belt structure 400, wherein the smoke pipe 100 includes a corrugated portion 110 and a straight tube portion 120 located at both ends of the corrugated portion 110, the air outlet seat and cap 200 of the air outlet seat can be extended into the straight tube portion 120, the check valve 300 can be extended into the straight tube portion 120, the sealing belt structure 400 can be cut into a preset length, and the sealing belt structure 400 cut into a preset length is respectively bent into a ring shape and compressed and clamped between the outer peripheral wall of the air outlet seat and cap 200 and the inner cavity wall of the straight tube portion 120, and compressed and clamped between the outer peripheral wall of the check valve 300 and the inner cavity wall of the straight tube portion 120, and the sealing belt structure 400 is configured to seal the air outlet seat and cap 200 and the straight tube portion 120 and to seal the check valve 300 and the straight tube portion 120.

[0049] The smoke pipe sealing device 1000 is configured to separate the smoke pipe 100 into a corrugated portion 110 and straight tube portions 120 arranged at both ends of the corrugated portion 110, and utilizes the structural characteristics of the corrugated portion 110 to ensure that the bending shape of the smoke pipe 100 is easily adjusted to meet actual installation requirements, and the inner cavity wall of the straight tube portion 120 is respectively connected with the outer peripheral wall of the air outlet seat and cap 200 on the air outlet seat and the outer peripheral wall of the check valve 300, and the sealing belt structure 400 is cut into a preset length, and the sealing belt structure 400 of the preset length is bent into a ring shape and compressed and clamped between the outer peripheral wall of the air outlet seat and cap 200 and the inner cavity wall of the straight tube portion 120. Between the cavity walls, and between the outer peripheral wall of the check valve 300 and the inner cavity wall of the straight cylinder portion 120, effective sealing of the straight cylinder portion 120 and the air outlet seat and cap 200, as well as effective sealing of the straight cylinder portion 120 and the check valve 300 can be achieved. The specific cutting length of the sealing belt structure 400 can be adjusted according to the actual specifications of the straight cylinder portion 120, the air outlet seat and cap 200 and the check valve 300 to meet the sealing requirements of the straight cylinder portion 120, the air outlet seat and cap 200 and the check valve 300 of different specifications. It has strong applicability and does not require a sealing ring that needs to be produced by mold opening, which can also effectively reduce production costs.

[0050] It should be noted that the specific structure and working principle of the corrugated portion 110 belong to the prior art and will not be described in detail here.

[0051] Furthermore, if Figure 4 and Figure 5As shown, the sealing belt structure 400 includes a first sealing belt 410 and a second sealing belt 420, wherein the first sealing belt 410 is annularly fixed on the inner cavity wall of the straight tube portion 120, the second sealing belt 420 is annularly fixed on the inner cavity wall of the annular first sealing belt 410, and the outer peripheral wall of the air outlet seat and cap 200 or the outer peripheral wall of the check valve 300 is tightly pressed against the inner cavity wall of the annular second sealing belt 420. By splitting the sealing belt structure 400 into the first sealing belt 410 fixed on the inner cavity wall of the straight tube portion 120 and the second sealing belt 420 fixed on the inner cavity wall of the first sealing belt 410, it is possible to achieve layered sealing of the straight tube portion 120 and the air outlet seat and cap 200 or the check valve 300, thereby improving the sealing effect.

[0052] In an optional embodiment, the deformation capacity of the second sealing belt 420 is better than the deformation capacity of the first sealing belt 410, or the deformation capacity of the second sealing belt 420 is the same as the deformation capacity of the first sealing belt 410. Since the first sealing belt 410 is fixed on the inner cavity wall of the straight tube part 120, the second sealing belt 420 is fixed on the inner cavity wall of the first sealing belt 410, and the second sealing belt 420 is tightly pressed against the outer peripheral wall of the air outlet seat and cap 200 or the outer peripheral wall of the check valve 300, the sealing belt structure 400 is fixed on the straight tube part 120, and by ensuring that the deformation capacity of the second sealing belt 420 is better than the deformation capacity of the first sealing belt 410 or the same as the deformation capacity of the first sealing belt 410, it can be ensured that the second sealing belt 420 pressed against the outer peripheral wall of the air outlet seat and cap 200 or the outer peripheral wall of the check valve 300 is fully compressed and deformed, thereby ensuring the sealing effect of the second sealing belt 420 and the air outlet seat and cap 200 or the check valve 300.

[0053] It should be noted that, in the present embodiment, the deformation capacity of the second sealing tape 420 is better than that of the first sealing tape 410. Specifically, the first sealing tape 410 is a PVC adhesive tape, and the second sealing tape 420 is an EVA adhesive pad tape. When it is necessary to complete the sealing of the straight tube portion 120 and the air outlet seat and cap 200, the PVC adhesive tape is first bonded and fixed to the inner cavity wall of the straight tube portion 120, and then the EVA adhesive pad tape is bonded to the inner cavity wall of the PVC adhesive tape, and finally the air outlet seat and cap 200 is inserted into the hole surrounded by the EVA adhesive pad tape to complete the sealing and fixing of the straight tube portion 120 and the air outlet seat and cap 200.

[0054] Moreover, since the first sealing tape 410 is a PVC adhesive tape and the second sealing tape 420 is an EVA adhesive pad tape, the smoke pipe 100, the air outlet seat and cap 200, the check valve 300, the first sealing tape 410 and the second sealing tape 420 can all be detachably fixed. During the transportation and storage of the smoke pipe sealing device 1000, the smoke pipe 100, the air outlet seat and cap 200, the check valve 300, the first sealing tape 410 and the second sealing tape 420 can be packaged separately, which saves space and reduces transportation and storage costs.

[0055] In other embodiments, the PVC adhesive tape may be adhered to the outer peripheral wall of the air outlet seat and cap 200, and then the EVA adhesive pad tape may be adhered to the outer peripheral wall of the PVC adhesive tape, and finally the air outlet seat and cap 200 adhered with the PVC adhesive tape and the EVA adhesive pad tape may be inserted into the inner cavity wall of the straight tube portion 120. This embodiment does not make specific limitations.

[0056] In addition, in other embodiments, the specific materials of the first sealing tape 410 and the second sealing tape 420 may also be adjusted according to actual needs, and this embodiment does not specifically limit this.

[0057] As an optional solution, the widths of the first sealing band 410 and the second sealing band 420 are the same as the axial length of the straight tube portion 120 , the first sealing band 410 completely covers the inner cavity wall of the straight tube portion 120 , and the second sealing band 420 completely covers the inner cavity wall of the first sealing band 410 . By ensuring that the widths of the first sealing belt 410 and the second sealing belt 420 are the same as the axial length of the straight tube portion 120, when the first sealing belt 410 is bent into a ring shape, the axial height of the first ring-shaped sealing belt 410 is the axial length of the straight tube portion 120, thereby allowing the first sealing belt 410 to completely cover the inner cavity wall of the straight tube portion 120. Since the width of the first sealing belt 410 is the same as that of the second sealing belt 420, the axial height of the ring-shaped second sealing belt 420 is the same as that of the ring-shaped first sealing belt 410, so that the second sealing belt 420 can completely cover the inner cavity wall of the first sealing belt 410, thereby ensuring the sealing effect of the straight tube portion 120 and the air outlet seat and cap 200 or the check valve 300.

[0058] As an optional scheme, the first annular sealing belt 410 and the second annular sealing belt 420 are both single-layer structures, and the planes where the fractures of the first annular sealing belt 410 and the fractures of the second annular sealing belt 420 are located coincide with the radial plane of the straight tube portion 120, and the fractures of the first annular sealing belt 410 and the fractures of the second annular sealing belt 420 are located at the upper end of the air outlet seat and cap 200 or the upper end of the check valve 300.

[0059] By arranging the first annular sealing belt 410 and the second annular sealing belt 420 into a single-layer structure, the planes where the fractures on the first annular sealing belt 410 and the fractures on the second annular sealing belt 420 are located coincide with the radial plane of the straight tube portion 120, ensuring that the fractures of the first annular sealing belt 410 and the fractures of the second annular sealing belt 420 are connected in the radial direction of the straight tube portion 120, and the two fractures are arranged at the upper end of the air outlet seat and cap 200 or the upper end of the check valve 300. After the smoke pipe sealing device 1000 has been working for a period of time, the smoke pipe sealing device 1000 It is inevitable that some oil stains will remain inside the smoke tube sealing device 1000. The oil stains remaining in the smoke tube sealing device 1000 will accumulate at the lower end of the smoke tube sealing device 1000 under the action of their own gravity, and the sealing effect of the fracture of the first annular sealing belt 410 and the fracture of the second annular sealing belt 420 is lower than that of the other parts. The oil stains can easily leak along the gaps at the fractures. Setting the two fractures at the upper end of the air outlet seat and the cap 200 or the upper end of the check valve 300 can prevent the oil stains accumulated at the lower end of the smoke tube sealing device 1000 from leaking along the fractures, thereby further improving the sealing effect and neatness of the smoke tube sealing device 1000.

[0060] Specifically, the thickness of the first sealing tape 410 is 0.5 mm to 1 mm, and the thickness of the second sealing tape 420 is 2 mm to 3 mm. In this embodiment, the thickness of the first sealing tape 410 is preferably 0.8 mm, and the thickness of the second sealing tape 420 is preferably 2.5 mm. In other embodiments, the thickness of the first sealing tape 410 can be adjusted arbitrarily within the range of 0.5 mm to 1 mm according to actual needs, and the thickness of the second sealing tape 420 can be adjusted within the range of 2 mm to 3 mm, which is not specifically limited in this embodiment.

[0061] In order to facilitate the setting of the break at the upper end of the air outlet seat and cap 200 or the upper end of the check valve 300, as shown in FIG. Figure 6 and Figure 7 As shown, the air outlet seat and cap 200 is provided with a first marking portion 240, and the first marking portion 240 is configured to point out the upper end of the air outlet seat and cap 200, and the check valve 300 is provided with a second marking portion 320, and the second marking portion 320 is configured to point out the upper end of the check valve 300. By providing the first marking portion 240 on the air outlet seat and cap 200 to point out the upper end of the air outlet seat and cap 200, when it is necessary to dock the straight tube portion 120 with the air outlet seat and cap 200, the first marking portion 240 can provide a guide for the docking operation of the staff, and by providing the second marking portion 320 on the check valve 300 to point out the upper end of the check valve 300, when it is necessary to dock the straight tube portion 120 with the check valve 300, the second marking portion 320 can provide a guide for the docking operation of the staff, and ensure that the break is set at the upper end of the air outlet seat and cap 200 or the upper end of the check valve 300.

[0062] Combination Figure 5 The specific structure of the air outlet seat cap 200 is described. A first annular protrusion 210 is provided at one end of the air outlet seat cap 200. The first annular protrusion 210 extends outward along the axial direction of the air outlet seat cap 200. The first sealing belt 410 and the second sealing belt 420 are compressed and clamped between the outer peripheral wall of the first annular protrusion 210 and the inner cavity wall of the straight tube part 120. By providing the first annular protrusion 210 extending outward along the axial direction at one end of the air outlet seat cap 200, the first annular protrusion 210 is used to achieve docking with the straight tube part 120, which has a simple structure and a clever design.

[0063] In addition, the end of the air outlet seat and cap 200 provided with the first annular protrusion 210 is also provided with a first annular groove 220, and the first annular groove 220 is provided on the outer periphery of the first annular protrusion 210, and the inner diameter circumferential wall of the first annular groove 220 is flush with the outer peripheral wall of the first annular protrusion 210, and the straight tube portion 120 can extend into the first annular groove 220. By providing the first annular groove 220 on the outer periphery of the first annular protrusion 210, the inner diameter circumferential wall of the first annular groove 220 is flush with the outer peripheral wall of the first annular protrusion 210, and when the straight tube portion 120 is docked with the first annular protrusion 210, the straight tube portion 120 can extend into the first annular groove 220 along the axial direction of the first annular protrusion 210, thereby improving the docking effect of the straight tube portion 120 and the air outlet seat and cap 200.

[0064] In addition, a matching thread 230 is provided on the inner cavity wall of the air outlet seat cap 200 away from the first annular protrusion 210 and the first annular groove 220, and a corresponding docking thread is provided on the outer circumferential wall of the docking portion of the air outlet seat, and the air outlet seat cap 200 is fixed to the air outlet seat thread to facilitate the assembly and docking of the air outlet seat cap 200 and the straight tube portion 120. In other embodiments, the matching thread 230 can also be provided on the outer circumferential wall of the air outlet seat cap 200 away from the first annular protrusion 210 and the first annular groove 220, and it is sufficient to provide the docking thread on the inner cavity wall of the docking portion of the air outlet seat, which is not specifically limited in this embodiment.

[0065] like Figure 4 and Figure 6As shown, in order to further improve the sealing effect between the first annular protrusion 210 and the straight tube portion 120, a first annular rib 211 is provided on the outer peripheral wall of the first annular protrusion 210 along its circumferential direction. When the straight tube portion 120 is butted against the first annular protrusion 210, the first sealing belt 410 and the second sealing belt 420 are both compressed and clamped between the inner cavity wall of the straight tube portion 120 and the outer peripheral wall of the first annular protrusion 210. Since the first annular rib 211 is provided on the outer peripheral wall of the first annular protrusion 210, the first sealing belt 410 and the second sealing belt 420 opposite to the first annular rib 211 are compressed and deformed to a greater extent, thereby further improving the sealing effect on the straight tube portion 120 and the first annular protrusion 210.

[0066] Further, a plurality of first annular ribs 211 are arranged at intervals along the axial direction of the first annular protrusion 210 on the outer peripheral wall of the first annular protrusion 210, and the plurality of first annular ribs 211 are arranged at equal intervals or unequal intervals. By arranging a plurality of first annular ribs 211 at equal intervals or unequal intervals along the axial direction of the first annular protrusion 210 on the first annular protrusion 210, each first annular rib 211 can improve the deformation degree of the first sealing belt 410 and the second sealing belt 420 corresponding thereto, thereby improving the sealing effect of the straight tube portion 120 and the first annular protrusion 210. It should be noted that in this embodiment, two first annular ribs 211 are arranged at equal intervals along the axial direction of the first annular protrusion 210 on the outer peripheral wall of the first annular protrusion 210. In other embodiments, the specific number of the first annular ribs 211 can also be adjusted according to actual needs, and the plurality of first annular ribs 211 can also be arranged at equal intervals or unequal intervals according to actual needs, which is not specifically limited in this embodiment.

[0067] Combination Figure 7 The specific structure of the check valve 300 is described. A second annular protrusion 310 is provided at one end of the check valve 300. The second annular protrusion 310 extends outward along the axial direction of the check valve 300. The first sealing belt 410 and the second sealing belt 420 are compressed and clamped between the outer peripheral wall of the second annular protrusion 310 and the inner cavity wall of the straight tube part 120. By providing a second annular protrusion 310 extending outward along the axial direction at one end of the check valve 300, the second annular protrusion 310 is used to achieve docking with the straight tube part 120, which has a simple structure and an ingenious design.

[0068] The specific structure of the second annular protrusion 310 is similar to that of the first annular protrusion 210.
