DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0028] In addition, the present disclosure can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.

[0029] The pipe of the device is generally used for water or ventilation, etc. If the cooperation between the pipe opening and the shell of the device is not tight enough, the sealing performance of the pipe will be affected. For example, in a drying device, there is a gap between the pipe opening of the pipe connected to the fan and the shell of the drying device, which causes poor sealing performance of the pipe and affects the air inlet or exhaust effect of the fan.

[0030] The technical solutions of the present disclosure will be described below in combination with the drawings and with reference to specific embodiments.

[0031] In a first aspect, some embodiments of the present disclosure provide a sealing device, comprising a sealing member configured to abut a pipe opening of a pipe with a shell to increase the sealing between the pipe and the shell.

[0032] The sealing device according to some embodiments of the present disclosure comprises a sealing member 1-200 applied to a drying apparatus, please refer to FIG. 101 to FIG. 103, the sealing member 1-200 can be arranged between a pipe of a fan 1-300 and a shell 1-400 to seal the gap between the pipe opening of the pipe and the shell 1-400. The pipe of the fan 1-300 can be an air outlet pipe or an air inlet pipe of the fan 1-300.

[0033] The sealing member 1-200 comprises a connecting portion 1-210 and a sealing portion 1-220, the sealing portion 1-220 is connected to the connecting portion 1-210; the connecting portion 1-210 is connected to a pipe body 1-100, and the sealing portion 1-220 abuts against an inner wall of the shell 1-400 to close the gap between the pipe body 1-100 and the shell 1-400.

[0034] By connecting the connecting portion 1-210 to the pipe body 1-100 and abutting the sealing portion 1-220 against the inner wall of the shell 1-400, the gap between the pipe body 1-100 and the shell 1-400 is closed by the sealing portion 1-220, which can prevent the fluid inside the pipe body 1-100 from overflowing through the gap between the pipe body 1-100 and the shell 1-400, thereby ensuring the normal operation of the pipe body 1-100. The connecting portion 1-210 is connected to the pipe body 1-100, and there is no need to provide a fixing structure on the shell 1-400 to fix the sealing portion 1-220, which reduces the processing difficulty of the shell 1-400. The pipe body 1-100 is preferably a hard structure, such as a pipe member made of hard plastic or metal.

[0035] In some embodiments, please refer to FIG. 102 to FIG. 103, the connecting portion 1-210 is sleeved on the pipe body 1-100, and the connection between the sealing member 1-200 and the pipe body 1-100 can be completed without additional tools; compared with the connection modes such as threaded connection and buckle connection, the connecting portion 1-210 is directly sleeved on the pipe body 1-100 in the present embodiment, and no additional processing is required on the pipe body 1-100 or the connecting portion 1-210.

[0036] In some embodiments, referring to FIG. 103, the sealing portion 1-220 is arranged around the connecting portion 1-210 and extends towards the inner side of the connecting portion 1-210. When the connecting portion 1-210 is sleeved on the pipe body 1-100, the sealing portion 1-220 can seal the pipe opening edge 1-110 of the pipe body 1-100 to reduce the gap between the pipe body 1-100 and the shell 1-400.

[0037] The connecting portion 1-210 can be made of a material with elasticity. By using the elasticity of the connecting portion 1-210 itself, the tightness of the connection between the connecting portion 1-210 and the pipe body 1-100 can be improved, and the sealing performance of the sealing device 1-200 can be improved to prevent fluid from overflowing from the gap between the connecting portion 1-210 and the pipe body 1-100. The contact portion of the sealing portion 1-220 and the shell 1-400 can be made of a flexible material, so that when the sealing portion 1-220 abuts against the inner wall of the shell 1-400, the contact portion of the sealing portion 1-220 and the shell 1-400 can be deformed to improve the sealing performance of the sealing portion 1-220. Of course, in other embodiments, the sealing portion 1-220 can also be made of a flexible material. The entire sealing device 1-200 can be made of the same material, which is convenient for processing the sealing device 1-200. For example, the sealing device 1-200 can be made of a silica gel material.

[0038] In some embodiments, referring to FIG. 103, the sealing portion 1-220 is provided with a sealing strip 1-221 on the side away from the connecting portion 1-210, and the sealing strip 1-221 abuts against the inner wall of the shell 1-400. The sealing strip 1-221 can form an effective seal at the interface between the pipe body 1-100 and the shell 1-400 to prevent liquid or gas from leaking out of the interface between the pipe body 1-100 and the shell 1-400. The sealing strip 1-221 can extend along the circumferential direction of the connecting portion 1-210. When the connecting portion 1-210 is connected to the pipe body 1-100, the sealing strip 1-221 corresponds to the pipe opening edge 1-110 of the pipe body 1-100, and the sealing performance between the pipe body 1-100 and the shell 1-400 is improved.

[0039] The shell 1-400 can be a cover body with an arc-shaped top. During use, the sealing device 1-200 is fixed on the pipeline body 1-100, and then the cover body is installed. The cover body is installed from top to bottom, so that the side wall of the cover body abuts on the sealing part 1-220, thereby reducing the gap between the pipeline body 1-100 and the shell 1-400 and improving the sealing performance. The cover body can be provided with a through hole 1-410. When the sealing part 1-220 abuts on the cover body, the through hole 1-410 communicates the inside of the pipeline body 1-100. The through hole 1-410 can be circular, square or other irregular shapes. The through hole 1-410 can be provided with one, two, three or four, and the shape and number of the through hole 1-410 are not limited in the embodiments of the present disclosure.

[0040] In some embodiments, referring to FIGS. 101 to 103, the sealing part 1-220 has an inclined guide surface 1-223. When the cover body is installed, the cover body is installed from top to bottom, and the inclined guide surface 1-223 is beneficial to the adhesion of the sealing part 1-220 to the curved surface of the cover body. The shape of the guide surface 1-223 can be set according to the shape of the side wall of the shell 1-400. The guide surface 1-223 can be a plane or an arc surface, as long as the guide surface 1-223 is adhered to the shape of the side wall of the shell 1-400. The guide surface 1-223 is the side of the sealing part 1-220 facing the shell 1-400, and the sealing strip 1-221 is formed on the guide surface 1-223.

[0041] In some embodiments, referring to FIG. 103, the sealing strip 1-221 forms a notch 1-222 on one side of the sealing part 1-220, so as to adjust the shape of the sealing part 1-220 and improve the adhesion of the sealing part 1-220 and the side wall of the shell 1-400. During installation, the top of the cover body is adhered to the notch 1-222 of the sealing strip 1-221, and the gap between the cover body and the sealing part 1-220 is reduced by the pressure of the cover body. The provision of the notch 1-222 can reduce the resistance of the cover body installation.

[0042] In some embodiments, referring to FIG. 104, the connecting part 1-210 forms an opening 1-211 on the side away from the sealing part 1-220, the edge of the opening 1-211 forms a tightening edge 1-212, the tension of the tightening edge 1-212 can strengthen the connection between the connecting part 1-210 and the pipeline body 1-100, and prevent the connecting part 1-210 and the pipeline body 1-100 from disengaging; the edge of the opening 1-211 forms the tightening edge 1-212, so that the opening 1-211 of the connecting part 1-210 is tightly attached to the pipeline body 1-100, which can improve the fit of the connecting part 1-210 and the pipeline body 1-100, thereby improving the sealing performance of the sealing device 1-200; at least part of the tightening edge 1-212 is bent to form a bending part 1-213, which can more evenly disperse stress, so that the tightening edge 1-212 is more flexible and elastic, which is conducive to the stretching and contraction of the tightening edge 1-212, thereby adjusting the elasticity of the connecting part 1-210. When installing the connecting part 1-210, the tightening edge 1-212 can be stretched to adjust the size of the opening 1-211, thereby facilitating the installation of the connecting part 1-210 on the pipeline body 1-100. The tightening edge 1-212 can be partially bent to form a bending part 1-213, or the tightening edge 1-212 can be fully bent to form a plurality of bending parts 1-213, and the specific shape of the tightening edge 1-212 is not particularly limited in the embodiments of the present disclosure.

[0043] In some embodiments, referring to FIG. 104, the tightening edge 1-212 is bent towards the sealing part 1-220 to form a bending part 1-213, which can improve the elasticity of the tightening edge 1-212 and facilitate the adjustment of the size of the opening 1-211; the tightening edge 1-212 is bent towards the sealing part 1-220, so that the bending part 1-213 forms a recess, which can reduce the material of the connecting part 1-210; in addition, the bending part 1-213 forms a recess, so that the fingers can be buckled in the recess when holding the sealing device 1-200, thereby avoiding slipping.

[0044] In some embodiments, referring to FIG. 104, the tightening edge 1-212 is a convex strip. The convex strip is arranged such that the tightening edge 1-212 protrudes from the surface of the connecting part 1-210, which facilitates the stretching of the tightening edge 1-212 and facilitates the disassembly and installation of the connecting part 1-210; in addition, the strength of the tightening edge 1-212 can be improved to prevent the tightening edge 1-212 from breaking after being stretched for multiple times during disassembly. In addition, the tightening edge 1-212 is located at the edge of the connecting part 1-210 and is prone to wear, and the tightening edge 1-212 is arranged as a convex strip, which can improve the hardness and wear resistance of the tightening edge 1-212.

[0045] In some embodiments, referring to FIG. 106, the connecting part 1-210 is provided with a reinforcing rib 1-240, which can effectively increase the mechanical strength and rigidity of the connecting part 1-210, improve the tensile strength, compressive strength and shear strength of the connecting part 1-210, and thus enhance the overall mechanical properties of the connecting part 1-210. The reinforcing rib 1-240 is arranged along the axial direction of the connecting part 1-210, which can increase the axial strength of the connecting part 1-210 and improve the overall rigidity of the connecting part 1-210; the reinforcing rib 1-240 can effectively resist the deformation of the connecting part 1-210, improve the stability and reliability of the connecting part 1-210, and avoid the shrinkage of the connecting part 1-210 during use, which affects the sealing performance of the sealing device 1-200.

[0046] In a second aspect, some embodiments of the present disclosure provide a pipe for end sealing, as shown in FIGS. 101-102, which comprises a pipe body 1-100 and the sealing device 1-200 described above.

[0047] It can be understood that the sealing device 1-200 has the beneficial effects of the above-mentioned embodiments, and therefore the pipe for end sealing also has the beneficial effects of the above-mentioned embodiments, the specific implementation of which can refer to the above-mentioned embodiments, which will not be repeated here.

[0048] In some embodiments, referring to FIGS. 106-107, one of the connecting part 1-210 and the pipe body 1-100 is provided with a clamping protrusion 1-120, and the other is provided with a clamping recess 1-230 matched with the clamping protrusion 1-120. The clamping protrusion 1-120 and the clamping recess 1-230 are matched to improve the reliability of the connection between the connecting part 1-210 and the pipe body 1-100. The clamping recess 1-230 can be provided on the connecting part 1-210, and the clamping protrusion 1-120 can be provided on the pipe body 1-100 correspondingly. In order to facilitate processing, the clamping recess 1-230 can penetrate the inner side and the outer side of the connecting part 1-210. The clamping recess 1-230 can be arranged between two adjacent reinforcing ribs 1-240 to avoid the breakage of the connecting part 1-210.

[0049] In one embodiment, the pipe body 1-100 is a hard structure. The hard structure can be metal, hard plastic or concrete, etc. The hard pipe body 1-100 is usually connected with equipment or other pipe bodies by screw connection, welding or other fastening methods. Compared with soft pipe bodies, the hard pipe body 1-100 has more stable and diverse connection methods, which can adapt to various installation environments. In addition, the hard pipe body 1-100 can withstand greater pressure, and is less likely to deform compared with soft pipes, thereby maintaining the smoothness and stability of the pipe interior.

[0050] In a third aspect, the present disclosure provides a drying apparatus comprising the hot air assembly, the housing 1-400 and the pipe as described above.

[0051] It can be understood that the sealing device 1-200 has the beneficial effects of the above-mentioned embodiments, and the drying apparatus accordingly has the beneficial effects of the above-mentioned embodiments, the specific implementation of which can refer to the above-mentioned embodiments, which will not be repeated herein. The drying apparatus includes but is not limited to a washing and drying all-in-one machine, a clothes dryer, a dishwasher, etc.

[0052] Referring to FIG. 105, the hot air assembly can include a fan 1-300 and a heater (not shown in the figure), and the heater is arranged in the fan 1-300 to heat the gas; the fan 1-300 has an air inlet end 1-310, and the pipe body 1-100 can be communicated with the air inlet end 1-310 to introduce the gas outside the drying apparatus into the fan 1-300.

[0053] In a fourth aspect, the present disclosure provides a pipe assembly, referring to FIGS. 201-202, the pipe assembly is installed in the interior of the housing 2-300, and the pipe assembly comprises the sealing member and the fixing member 2-200 as described above, the sealing member comprises the pipe body 2-100, and the pipe body 2-100 has an open end 2-110; the fixing member 2-200 comprises a base 2-210 and a support part 2-220, and the support part 2-220 is connected to the base 2-210; the support part 2-220 is suitable for fixing the pipe body 2-100, so that the end face of the open end 2-110 of the pipe body 2-100 abuts against the inner wall of the housing 2-300.

[0054] The base 2-210 is used to fix the fixing member 2-200, and the pipe body 2-100 is fixed by the support part 2-220, so that the end face of the open end 2-110 of the pipe body 2-100 abuts against the inner wall of the housing 2-300, to ensure the sealing between the open end 2-110 of the pipe body 2-100 and the housing 2-300, and avoid the fluid overflowing from the gap between the pipe body 2-100 and the housing 2-300.

[0055] The pipe body 2-100 is suitable for the fluid such as liquid and gas to pass through, and the support part 2-220 can fix the pipe body 2-100 at a specific mounting position 2-221 and maintain a specific angle, to avoid the pipe body 2-100 from being deviated by the impact of the fluid inside the pipe body 2-100 during the working process.

[0056] The contact part of the opening end 2-110 and the shell 2-300 can be made of soft material, so that the opening end 2-110 is deformed when abutting, so as to reduce the gap between the opening end 2-110 and the shell 2-300, and reduce the risk of fluid in the pipeline body 2-100 overflowing from the gap between the opening end 2-110 and the shell 2-300. Of course, in other embodiments, the pipeline body 2-100 can be entirely made of soft material, and the angle of the pipeline body 2-100 can be freely changed to improve the flexibility of use.

[0057] Generally, a through hole 2-340 is arranged on the shell 2-300, and when the pipeline body 2-100 abuts against the inner wall of the shell 2-300, the pipeline body 2-100 communicates with the through hole 2-340, and the fluid in the pipeline body 2-100 flows out through the opening end 2-110 and the through hole 2-340 on the shell 2-300.

[0058] In some embodiments, referring to FIG. 202, the support part 2-220 is sleeved on the pipeline body 2-100, that is, the pipeline body 2-100 is fixed by the support part 2-220. Compared with other connection methods such as threaded connection, the support part 2-220 of the embodiment of the present disclosure is sleeved on the pipeline body 2-100, and the connection between the fixing part 2-200 and the pipeline body 2-100 can be completed without additional tools, which is simple and fast to operate.

[0059] In some embodiments, referring to FIGS. 202-203, the pipeline body 2-100 includes an extension part 2-120 and a body part 2-130, the extension part 2-120 is connected to the body part 2-130, and the extension part 2-120 is folded outward from the opening end 2-110, and a clamping groove 2-140 is formed between the extension part 2-120 and the outer wall of the body part 2-130; the support part 2-220 is at least partially clamped in the clamping groove 2-140. The support part 2-220 is at least partially clamped in the clamping groove 2-140, which can improve the reliability of the connection between the support part 2-220 and the pipeline body 2-100, and prevent the pipeline body 2-100 from sliding out of the support part 2-220. The extension part 2-120 is folded outward from the opening end 2-110, and the clamping groove 2-140 is formed between the extension part 2-120 and the outer wall of the body part 2-130, which can more accurately control the direction of the opening end 2-110, and is conducive to the close fit of the opening end 2-110 and the shell 2-300. The extension part 2-120 is folded outward from the opening end 2-110, which further limits the relative displacement between the pipeline body 2-100 and the support part 2-220, and the clamping groove 2-140 can be formed without machining the pipeline body 2-100, thereby simplifying the machining process of the pipeline body 2-100. Of course, in other embodiments, the support part 2-220 can also be entirely clamped in the clamping groove 2-140.

[0060] In some embodiments, referring to FIGS. 202-203, one of the extension part 2-120 and the support part 2-220 is provided with a protrusion 2-222, and the other is provided with a corresponding recess 2-121. Through the cooperation of the protrusion 2-222 and the recess 2-121, the reliability of the connection between the support part 2-220 and the pipeline body 2-100 can be further improved, and displacement between the support part 2-220 and the pipeline body 2-100 can be prevented to ensure the stability of the pipeline assembly in operation; at the same time, the cooperation of the protrusion 2-222 and the recess 2-121 has a certain positioning effect, so that the pipeline body 2-100 can be quickly installed at the correct position. The protrusion 2-222 and the recess 2-121 can be provided in multiple corresponding positions to improve the fixing effect; the number of the protrusion 2-222 and the recess 2-121 can be set according to actual needs, and the number of the protrusion 2-222 and the recess 2-121 is not particularly limited in the embodiments of the present disclosure. The recess 2-121 can be arranged at the end of the extension part 2-120, which facilitates the cooperation of the recess 2-121 and the protrusion 2-222, and is also conducive to the processing of the recess 2-121.
