[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those skilled in the art can recognize the application of other processes and / or the use of other materials.

[0036] The pipes of equipment are generally used for water or ventilation. If the pipe opening of the pipe is not tightly matched with the outer shell of the equipment, the sealing of the pipe will be affected. For example, in a drying device, there is a gap between the pipe opening of the pipe connecting the fan and the outer shell of the drying device, resulting in poor sealing of the pipe, affecting the air intake or exhaust effect of the fan.

[0037] The present invention is described below with reference to the accompanying drawings and specific embodiments:

[0038] The first embodiment of the utility model provides a sealing device 200, which is applied to a drying device. Figures 1 to 3The sealing device 200 can be arranged between the pipe and the housing of the fan to seal the gap between the pipe opening of the pipe and the housing. The pipe of the fan can be an air outlet pipe or an air inlet pipe of the fan.

[0039] The sealing device 200 includes a connecting portion 210 and a sealing portion 220 . The sealing portion 220 is connected to the connecting portion 210 . The connecting portion 210 is connected to the pipe body 100 . The sealing portion 220 abuts against the inner wall of the shell 400 to close the gap between the pipe body 100 and the shell 400 .

[0040] The connection part 210 is connected to the pipe body 100, and the sealing part 220 abuts against the inner wall of the shell 400. The sealing part 220 is used to close the gap between the pipe body 100 and the shell 400, so that the fluid inside the pipe body 100 can be prevented from overflowing from the gap between the pipe body 100 and the shell 400, thereby ensuring the normal operation of the pipe body 100. The connection part 210 is connected to the pipe body 100, and there is no need to set a fixing structure on the shell 400 to fix the sealing part 220, which reduces the processing difficulty of the shell 400. The pipe body 100 is preferably a hard structural member, such as a pipe member made of hard plastic or metal.

[0041] In some embodiments, see Figures 2 to 3 The connecting portion 210 is sleeved on the pipe body 100, and the connection between the sealing device 200 and the pipe body 100 can be completed without additional tools; compared with connection methods such as threaded connection and snap connection, the embodiment of the utility model directly sleeves the connecting portion 210 on the pipe body 100, and no additional processing is required on the pipe body 100 or the connecting portion 210.

[0042] In some embodiments, see Figure 3 The sealing portion 220 is disposed around the connecting portion 210 and extends toward the inner side of the connecting portion 210. When the connecting portion 210 is sleeved on the pipe body 100, the sealing portion 220 can seal the pipe opening edge 110 of the pipe body 100 to reduce the gap between the pipe body 100 and the housing 400.

[0043] The connecting portion 210 may be made of an elastic material. By utilizing the elasticity of the connecting portion 210 itself, the tightness of the connection between the connecting portion 210 and the pipeline body 100 can be improved, and the sealing performance of the sealing device 200 can be improved to prevent the fluid from overflowing from the gap between the connecting portion 210 and the pipeline body 100. The contact portion between the sealing portion 220 and the housing 400 may be made of a flexible material, so that when the sealing portion 220 abuts against the inner wall of the housing 400, the contact portion between the sealing portion 220 and the housing 400 may be deformed to improve the sealing performance of the sealing portion 220; of course, in other embodiments, the sealing portion 220 may also be made entirely of a flexible material. The entire sealing device 200 may be made of the same material to facilitate the processing of the sealing device 200; for example, the sealing device 200 may be made of silicone.

[0044] In some embodiments, see Figure 3 The sealing portion 220 is provided with a sealing strip 221 on a side away from the connecting portion 210, and the sealing strip 221 abuts against the inner wall of the housing 400. The sealing strip 221 can form an effective seal at the interface between the pipeline body 100 and the housing 400 to prevent liquid or gas from leaking out of the interface between the pipeline body 100 and the housing 400. The sealing strip 221 can extend along the circumferential direction of the connecting portion 210. When the connecting portion 210 is connected to the pipeline body 100, the sealing strip 221 corresponds to the pipe opening edge 110 of the pipeline body 100, thereby enhancing the sealing between the pipeline body 100 and the housing 400.

[0045] The housing 400 may be a cover with an arc-shaped top. During use, the sealing device 200 is fixed on the pipe body 100, and then the cover is installed; the cover is installed from top to bottom, so that the side wall of the cover abuts against the sealing part 220, thereby reducing the gap between the pipe body 100 and the housing 400 and improving the sealing performance. A through hole 410 may be provided on the cover, and when the sealing part 220 abuts against the cover, the through hole 410 communicates with the interior of the pipe body 100; the through hole 410 may be circular, square or other irregular shapes, and one, two, three or four through holes 410 may be provided. The embodiment of the utility model does not limit the shape and number of the through holes 410.

[0046] In some embodiments, see Figures 1 to 3 The sealing part 220 has an inclined guide surface 223. When the cover is installed, the cover is installed from top to bottom. The inclined guide surface 223 is conducive to the sealing part 220 to fit the curved surface of the cover. The shape of the guide surface 223 can be set according to the shape of the side wall of the shell 400; the guide surface 223 can be a plane or a curved surface, as long as the guide surface 223 fits the shape of the side wall of the shell 400; wherein the guide surface 223 is the side of the sealing part 220 facing the shell 400, and the sealing strip 221 is formed on the guide surface 223.

[0047] In some embodiments, see Figure 3 The sealing strip 221 forms a notch 222 on one side of the sealing part 220 to adjust the shape of the sealing part 220 and improve the fit between the sealing part 220 and the side wall of the housing 400; during installation, the top of the cover body is fitted to the notch 222 of the sealing strip 221, and the pressure of the cover body is used to reduce the gap between the cover body and the sealing part 220; the setting of the notch 222 can reduce the resistance of the cover body installation.

[0048] In some embodiments, see Figure 4 The connection part 210 forms an opening 211 on a side away from the sealing part 220, and the edge of the opening 211 forms a tightening edge 212. The tension of the tightening edge 212 can strengthen the connection between the connection part 210 and the pipeline body 100 to prevent the connection part 210 and the pipeline body 100 from being out of fit; the edge of the opening 211 forms the tightening edge 212, so that the opening 211 of the connection part 210 is closely attached to the pipeline body 100, which can improve the fit between the connection part 210 and the pipeline body 100, thereby improving the sealing performance of the sealing device 200; at least part of the tightening edge 212 is bent to form a bend 213, which can more evenly disperse the stress, make the tightening edge 212 more flexible and elastic, and facilitate the stretching and contraction of the tightening edge 212, thereby adjusting the elasticity of the connection part 210. When installing the connection part 210, the tightening edge 212 can be stretched to adjust the size of the opening 211, so that the connection part 210 can be conveniently sleeved on the pipeline body 100. The tightening edge 212 may be partially bent to form a bend 213 , or the tightening edge 212 may be completely bent to form a plurality of bends 213 . The embodiment of the utility model does not particularly limit the specific shape of the tightening edge 212 .

[0049] In some embodiments, see Figure 4 The tightening edge 212 is bent toward one side of the sealing portion 220 to form a bend 213, which can improve the elasticity of the tightening edge 212 and is beneficial for adjusting the size of the opening 211; the tightening edge 212 is bent toward one side of the sealing portion 220, so that the bend 213 forms a depression, which can reduce the material of the connecting portion 210; in addition, the bend 213 forms a depression, and when taking the sealing device 200, the fingers can be buckled in the depression to avoid slipping.

[0050] In some embodiments, see Figure 4, the tightening edge 212 is a convex strip. The setting of the convex strip makes the tightening edge 212 protrude from the surface of the connecting portion 210, which is convenient for stretching the tightening edge 212 and is conducive to the disassembly and installation of the connecting portion 210; secondly, the strength of the tightening edge 212 can be improved to prevent the tightening edge 212 from breaking after multiple stretching during the disassembly process. In addition, the tightening edge 212 is located at the edge of the connecting portion 210 and is easily worn. Setting the tightening edge 212 as a convex strip can improve the hardness and wear resistance of the tightening edge 212.

[0051] In some embodiments, see Figure 6 The connection part 210 is provided with reinforcing ribs 240, which can effectively increase the mechanical strength and rigidity of the connection part 210, improve the tensile strength, compressive strength and shear strength of the connection part 210, and thus enhance the overall mechanical properties of the connection part 210. The reinforcing ribs 240 are arranged along the axial direction of the connection part 210, which can increase the axial strength of the connection part 210 and improve the overall rigidity of the connection part 210; the reinforcing ribs 240 can effectively resist the deformation of the connection part 210, improve the stability and reliability of the connection part 210, and prevent the connection part 210 from shrinking during use, which affects the sealing performance of the sealing device 200.

[0052] The second embodiment of the utility model provides a pipeline for end sealing, such as Figures 1 to 2 As shown, it includes a pipe body 100 and the above-mentioned sealing device 200.

[0053] It can be understood that the sealing device 200 has the beneficial effects of the above-mentioned embodiment, and the pipe used for end sealing correspondingly has the beneficial effects of the above-mentioned embodiment.

[0054] In some embodiments, see Figure 6 to Figure 7 One of the connection part 210 and the pipe body 100 is provided with a snap-fit ​​protrusion 120, and the other is provided with a snap-fit ​​recess 230 that cooperates with the snap-fit ​​protrusion 120. Through the cooperation between the snap-fit ​​protrusion 120 and the snap-fit ​​recess 230, the reliability of the connection between the connection part 210 and the pipe body 100 is improved. The snap-fit ​​recess 230 can be provided on the connection part 210, and the snap-fit ​​protrusion 120 is correspondingly provided on the pipe body 100; for the convenience of processing, the snap-fit ​​recess 230 can pass through the inside and outside of the connection part 210; the snap-fit ​​recess 230 can be provided between two adjacent reinforcing ribs 240 to prevent the connection part 210 from breaking.

[0055] In one embodiment, the pipe body is a hard structural part. The hard structural part can be metal, hard plastic or concrete, etc. The hard pipe body is usually connected to the equipment or other pipe body by threaded connection, welding or other fastening methods. Compared with the soft pipe body, the connection method of the hard pipe body is more secure and diverse, and can adapt to various installation environments. In addition, the hard pipe body can withstand greater pressure, and compared with the soft pipe, the hard pipe is not easy to deform, so as to maintain the patency and stability of the inside of the pipe.
