Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a pipeline structure, a drainage system and air-conditioning equipment. Background Art

[0002] As a device for conveying gas, liquid or solid particles, pipelines are widely used in gas systems, water supply systems, drainage systems and material conveying systems. In order to fix the pipelines, they are often fixed by means of clamps, bolts or mounting holes. Since the clamp and bolt connection methods require a lot of time to assemble, more and more pipelines choose to set annular grooves on the pipe body that match the diameter of the mounting hole to achieve pipeline fixation.

[0003] Taking the drain pipe in the air conditioning system as an example, in order to allow the end of the drain pipe to pass through the sheet metal mounting part and achieve engagement, a clamping part made of elastic material is set on the outer periphery of the drain pipe, and an annular clamping groove and an annular limiting structure are provided on the clamping part. When one end of the pipeline passes through the mounting hole on the sheet metal mounting part, the annular clamping groove is engaged with the mounting hole, and the annular limiting structure abuts against the side of one side of the sheet metal mounting part to limit the drain pipe. In the process of the clamping part being squeezed into the mounting hole by deformation, the deformation capacity of the clamping part is limited due to the large structural strength of the annular limiting structure, which makes it difficult for the clamping part to pass through the mounting hole. The assembly process is time-consuming and labor-intensive, which increases the labor intensity of the workers and is not conducive to the efficient assembly of the pipeline structure. Summary of the invention

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0043] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0044] In order to solve the technical problem in the prior art that when the pipeline structure is clamped by an elastic clamping part, the structural strength of the limiting structure on one side of the clamping groove is relatively large, and the deformation of the elastic clamping part is relatively difficult, resulting in a time-consuming and labor-intensive assembly process, the present application provides a pipeline structure, a drainage system and air-conditioning equipment, the pipeline structure is provided with an elastic clamping part 2 at the first end of the pipe body 1, and the limiting structure 22 in the elastic clamping part 2 is provided with a deformation-making notch 221 on its outer periphery, and one or more weak strength areas can be formed on the outer periphery of the limiting structure 22, so that when the elastic clamping part 2 passes through the mounting hole, the elastic clamping part 2 is more likely to shrink and deform, which can significantly reduce the difficulty of shrinking and deforming the elastic clamping part 2, reduce the labor intensity of workers during the assembly process, and improve the assembly efficiency of the pipeline fixedly connected by a clamping connection.

[0045] See also Figures 1 to 10 In a first aspect, an embodiment of the present application provides a pipeline structure, including a pipe body 1, a first end of the pipe body 1 is provided with an elastic clamping portion 2, which has elastic deformation capability. When the elastic clamping portion 2 passes through a mounting hole for fixing the pipe structure, the elastic clamping portion 2 can shrink and deform under the extrusion of the inner circumference of the mounting hole, so that the first end of the pipe body 1 can extend out of the mounting hole, such as Figure 8 and Fig. 9 shown.

[0046] The elastic clamping portion 2 includes an annular clamping groove 21 and a limiting structure 22 which are sequentially arranged along the axial direction of the tube body 1. Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, in the assembly direction of the elastic clamping portion 2 relative to the mounting hole (the elastic clamping portion 2 is along the Figure 7 The annular groove 21 is located at the front end of the limiting structure 22. When the annular groove 21 is connected to the mounting hole, the limiting structure 22 abuts against the side of the plate on one side of the mounting hole to prevent the first end of the tube body 1 from extending further forward. Figure 8 and Fig. 9 shown.

[0047] The outer periphery of the limiting structure 22 is provided with a deformation-free notch 221. Figure 1 , Figure 4 and Figure 5 As shown, one or more weak strength areas can be formed on the periphery of the limiting structure 22; when the elastic clamping part 2 shrinks and deforms, other parts in the limiting structure 22 can shrink and squeeze toward the area where the deformation yielding notch 221 is located, which can significantly reduce the difficulty of shrinkage and deformation of the limiting structure 22 and the elastic clamping part 2. The assembler can use a smaller extrusion force to achieve the engagement between the elastic clamping part 2 and the mounting hole, which can reduce the labor intensity of the workers during the assembly process and improve the assembly efficiency of the pipeline structure fixedly connected by a clamping connection.

[0048] It should be noted that when the deformation clearance notch 221 is not set, the limiting structure 22 is an annular stable structure. When subjected to radial compression by the inner wall of the mounting hole, the elastic material in the complete annular limiting structure 22 will generate annular stress to try to resist deformation, thereby increasing the difficulty of shrinkage deformation of the elastic clamping part 2 as a whole.

[0049] When a deformation-yielding notch 221 is provided on the outer periphery of the limiting structure 22, a complete and uniform annular stress cannot be formed inside the limiting structure 22 to resist deformation. The deformation-yielding notch 221 creates a weak strength area on the limiting structure 22. Other parts of the limiting structure 22 can move toward the area where the deformation-yielding notch 221 is located and shrink, aggravating the local shrinkage of the limiting structure 22, thereby significantly reducing the difficulty of shrinkage deformation of the limiting structure 22 and the elastic clamping portion 2.

[0050] In the above embodiment, the deformation-yielding notch 221 can be a hollow structure arranged on the outer periphery of the limiting structure 22, and its cross-sectional shape can be U-shaped, V-shaped, semicircular or irregular, etc., all of which can achieve the purpose of the present application.

[0051] In some embodiments of this application, please refer to Figure 4 and Figure 5 The deformation clearance notch 221 is a U-shaped notch, and the deformation clearance notch 221 is set along the radial extension of the limiting structure 22. When the elastic clamping part 2 shrinks and deforms, the deformation clearance notch 221 is set along the radial extension of the limiting structure 22, which can facilitate the areas on both sides of the deformation clearance notch 221 to shrink circumferentially toward the deformation clearance notch 221, thereby realizing the overall volume shrinkage of the elastic clamping part 2.

[0052] In some embodiments of this application, please refer to Figure 4 and Figure 5 There are multiple deformation clearance notches 221, which are radially arranged on the periphery of the limiting structure 22. While forming multiple equidistantly distributed weak strength areas on the periphery of the limiting structure 22, the limiting structure 22 can undergo relatively uniform shrinkage deformation in the circumferential direction.

[0053] In some embodiments of this application, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The elastic clamping part 2 is arranged around the outer circumference of the tube body 1, and one end of the elastic clamping part 2 is connected to the end of the tube body 1. A deformation clearance space 3 is formed between the inner circumference of the elastic clamping part 2 and the outer circumference of the tube body 1. When the elastic clamping part 2 is radially squeezed by the inner circumference of the mounting hole, the deformation clearance space 3 will not provide radial support for the elastic clamping part 2. The elastic clamping part 2 can radially shrink toward the deformation clearance space 3, so that the elastic clamping part 2 is easier to move relative to the mounting hole in the radial and axial directions until the mounting hole is engaged with the annular groove 21.

[0054] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 7 The elastic clamping portion 2 also includes a guide structure 23. In the axial direction of the tube body 1, the guide structure 23 and the limiting structure 22 are respectively located on both sides of the annular groove 21. The guide structure 23 can guide the mounting hole during the assembly process, so that the mounting hole can quickly approach the annular groove 21, which is conducive to the efficient assembly of the mounting hole and the annular groove 21.

[0055] In some embodiments of this application, please refer to Figure 7The guide structure 23 has a small diameter end and a large diameter end. The small diameter end is connected to the end of the tube body 1, so that the end of the tube body 1 and the small diameter end of the guide structure 23 can pass through the installation hole in sequence. The large diameter end is located at one end of the guide structure 23 close to the annular groove 21, and the diameter of the large diameter end is larger than the diameter of the annular groove 21. During the assembly process, the diameter of the large diameter end can shrink to facilitate the large diameter end to pass through the installation hole. When the installation hole and the annular groove 21 are engaged, the guide structure 23 returns to its original state under the action of elastic force, and the inner diameter of the installation hole matches the diameter of the annular groove 21. The diameter of the large diameter end and the maximum outer diameter of the limiting structure 22 are both larger than the inner diameter of the installation hole, which can prevent the installation hole from being separated from the annular groove 21, which is conducive to improving the connection stability between the elastic clamping part 2 and the installation hole.

[0056] In the above embodiment, the outer peripheral surface of the guide structure 23 may be a conical surface or an arcuate surface, both of which can achieve the purpose of the present application.

[0057] In some preferred embodiments of this application, please refer to Figure 7 The outer peripheral surface of the guide structure 23 is a conical surface set at an angle to the axis of the tube body 1. The radial difference H1 between the large diameter end of the guide structure 23 and the annular groove 21 is smaller than the radial dimension H2 of the deformation clearance space 3, so that the large diameter end of the guide structure 23 can be contracted toward the deformation clearance space 3, and then the contracted large diameter end of the guide structure 23 can smoothly pass through the mounting hole whose diameter matches the annular groove 21 (the diameter of the mounting hole is equal to or slightly larger than the minimum outer diameter of the annular groove 21).

[0058] In some embodiments of this application, please refer to Figure 7 The large diameter end of the guide structure 23 is provided with a fillet portion 231, which extends along the circumference of the large diameter end. When the large diameter end of the guide structure 23 passes through the mounting hole, the fillet portion 231 can achieve circumferential contact with the inner wall of the mounting hole. One side of the fillet portion 231 is connected to the outer peripheral surface of the guide structure 23, and the other side of the fillet portion 231 is connected to the end surface of the large diameter end, so that a transition connection between the outer peripheral surface of the guide structure 23 and the end surface of the large diameter end can be achieved. The arc surface formed by the fillet portion 231 reduces the difficulty of the large diameter end passing through the mounting hole.

[0059] In traditional drainage structures, for example, the water pump drainage pipe of a traditional duct machine is composed of a metal drainage joint and a rubber drainage pipe, or an elastic clip joint and a metal pipe body. The connection and installation of the water pump drainage pipe need to be achieved through subsequent assembly. There are problems such as backward production technology, many manual operation hours, and a large number of total parts, which will seriously lead to increased costs. In addition, there will be problems with the appearance of the splicing joints being unsightly during the splicing process.

[0060] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 6 The pipe body 1 and the elastic clamping part 2 are an integrated structure, and the integrated pipeline structure is manufactured by an integrated injection molding process of elastic materials, which can reduce the total number of parts and manufacturing costs of the pipeline structure. In addition, when the pipe body 1 and the elastic clamping part 2 are split structures, the appearance of the spliced ​​joint is likely to be unsightly after assembly. The present application realizes the connection between the pipe body 1 and the elastic clamping part 2 through an integrated injection molding process, which can improve the aesthetics of the pipeline structure at the connection part.

[0061] It should be noted that the present application prepares the pipe body 1 and the elastic clamping part 2 by elastic material, so that the overall pipeline structure has elastic buffering properties, which can effectively reduce the transmission of system vibrations, avoid vibration of the plate body (such as the mounting frame 5, etc.) where the mounting hole is located, and can effectively reduce the transmission of noise in usage scenarios such as drainage systems and air-conditioning equipment.

[0062] In the above embodiment, the elastic material used to prepare the pipeline structure can be rubber, silicone, polyurethane, thermoplastic elastomer, etc. Specifically, the appropriate elastic material can be selected according to the type of working fluid transmitted inside the pipe body 1 to realize the production of the pipeline structure.

[0063] In some embodiments of the present application, the material of the tube body 1 and the elastic clamping part 2 is rubber, so that the overall pipeline structure has good flexibility and wear resistance, high compressive strength and corrosion resistance, and can significantly improve the service life of the pipeline structure.

[0064] It should be noted that since the elastic clamping part 2 has a large diameter end of the guide structure 23 and a limiting structure 22 at the front and rear ends of the annular clamping groove 21, and the diameter of the large diameter end of the guide structure 23 and the outer diameter of the limiting structure 22 are both larger than the diameter of the mounting hole, after the annular clamping groove 21 and the mounting hole are snap-connected, the large diameter end of the guide structure 23 and the limiting structure 22 return to the uncontracted state, and the large diameter end of the guide structure 23 and the limiting structure 22 can be used to limit the two sides of the mounting hole to prevent the elastic clamping part 2 from escaping from the mounting hole during use.

[0065] In some embodiments of this application, please refer to Figure 6 and Figure 7 The first end of the tube body 1 is provided with a guide section 11, which can adjust the flow direction and pressure of the fluid inside the tube body 1 at the end of the tube body 1, which is beneficial to improving the stability of the connection between the tube body 1 and the mounting hole.

[0066] In some embodiments of this application, please refer to Figure 6 and Figure 7The first end of the tube body 1 is the discharge end. In the direction of fluid flow inside the tube body 1, the inner wall of the guide section 11 is gradually widened, which can slowly reduce the outflow pressure and speed of the fluid, and avoid high-frequency jitter at the end of the tube body 1 due to excessive fluid pressure and speed, which affects the stability of fluid discharge.

[0067] In the above embodiment, the fluid in the pipeline structure can be liquid, gas or solid particles and other fluids that need to be transported through the pipeline. The pipeline structure can be fixed at the mounting hole through the elastic clamping part 2, which facilitates the layout of the pipeline structure.

[0068] In some embodiments of the present application, the pipeline structure is used to achieve water discharge. The end of the first end of the pipe body 1 has a water outlet section 12 connected to the diversion section 11, which can transport the water body with slowed flow rate to a preset area. The diameter of the water outlet section 12 is the same as the maximum diameter of the diversion section 11, which can achieve smooth outflow of water. The length and shape of the water outlet section 12 can be set as needed and are not limited here.

[0069] See also Figures 1 to 10 The second aspect of the embodiment of the present application provides a drainage system, including the pipeline structure in the above embodiment, and also including a pump 4, which can be used to provide power for the flow of water in the pipeline structure. The pump 4 is provided with a discharge pipeline 41, and the second end of the pipe body 1 has a connecting sleeve section 13, which is sleeved on the outside of the discharge pipeline 41 to achieve the connection between the discharge pipeline 41 and the second end of the pipe body 1, such as Figure 7 , Figure 8 and Fig. 9 As shown, the water body is discharged by passing through the discharge pipeline 41, the middle section of the pipe body (ie, the transmission section 14), the diversion section 11 and the water outlet section 12 in sequence.

[0070] It should be noted that since the tube body 1 is made of elastic material, the connecting sleeve section 13 can achieve an interference fit with the discharge pipe 41 through elastic deformation, thereby preventing water from leaking from the connection gap between the discharge pipe 41 and the connecting sleeve section 13, and improving the connection sealing between the pump component 4 and the pipeline structure.

[0071] In some embodiments of this application, please refer to Figure 6 and Figure 8 The pipe body 1 includes a transmission section 14 connected to the connecting sleeve section 13. The inner diameter of the connecting sleeve section 13 matches the outer diameter of the discharge pipeline 41, which can be used to achieve a sealing sleeve on the outer peripheral surface of the discharge pipeline 41. The inner diameter of the transmission section 14 matches the inner diameter of the discharge pipeline 41, which can avoid blockage or eddy current inside the transmission section 14 due to a sudden change in the inner diameter of the pipeline when water flows from the discharge pipeline 41 to the transmission section 14.

[0072] Specifically, when the inner diameter of the transmission section 14 is much smaller than the inner diameter of the discharge pipeline 41, the flow cross-section of the water body is sharply reduced, causing the water pressure inside the transmission section 14 to increase rapidly. At the same time, the inner wall of the transmission section 14 will also hinder the flow of water, causing the water body to be blocked inside the transmission section 14.

[0073] When the inner diameter of the transmission section 14 is much larger than the inner diameter of the discharge pipe 41, the flow cross-section of the water body expands sharply, and it is easy to form a vortex at the connection between the transmission section 14 and the discharge pipe 41. When there is a corner in the discharge pipe 41, water will accumulate at the corner, resulting in kinetic energy loss of the water body, resulting in a reduction in the lift and energy efficiency of the pump 4.

[0074] In some preferred embodiments of this application, please refer to Fig.10 The inner diameter of the connecting sleeve section 13 forms an interference fit with the outer diameter of the discharge pipeline 41, and the discharge pipeline 41 can be sleeved and sealed by the elastic deformation of the connecting sleeve section 13. The inner diameter of the transmission section 14 is the same as the inner diameter of the discharge pipeline 41, so that water can flow smoothly from the discharge pipeline 41 to the inside of the transmission section 14, and there is no drop in the flow field between the discharge pipeline 41 and the transmission section 14, and no water blockage, vortex or energy loss will occur.

[0075] In some embodiments of this application, please refer to Fig.10 Since there is a difference in the inner diameters of the connecting sleeve section 13 and the transmission section 14, a limiting sink is formed between the connecting sleeve section 13 and the transmission section 14, which can be used to limit the end of the discharge pipeline 41. When the end face of the discharge pipeline 41 abuts against the limiting sink, the operator can sense that the assembly between the connecting sleeve section 13 and the discharge pipeline 41 is in place, which is conducive to improving assembly efficiency and convenience.

[0076] In some embodiments of this application, please refer to Figure 8 and Fig. 9 In order to further strengthen the connection reliability between the connecting sleeve section 13 and the discharge pipeline 41, a fixing part 6 is provided on the outer periphery of the connecting sleeve section 13, so as to prevent the connecting sleeve section 13 from being detached from the discharge pipeline 41 due to irreversible elastic deformation caused by long-term exposure to high pressure of water.

[0077] In some embodiments of the present application, the fixing member 6 is an adjustable clamp, which can adjust the inner diameter of the clamp, and the connecting sleeve section 13 is tightly clamped to the outside of the discharge pipeline 41 through the clamp.

[0078] In the above embodiment, the length and shape of the transmission section 14 can be designed according to the layout requirements of the pipeline structure, and can be a straight, L-shaped or curved pipe section, all of which can achieve the purpose of the present application.

[0079] In some embodiments of this application, please refer to Figure 8 and Fig. 9 The drainage system also includes a mounting frame 5, on which the pump component 4 is arranged. The mounting frame 5 is provided with a mounting hole, and the elastic clamping portion 2 is clamped and connected to the mounting hole, which can be used to achieve the fixed arrangement of the pump component 4 and the pipeline structure on the mounting frame 5.

[0080] It should be noted that the mounting frame 5 can be a rigid structural member in the area where the drainage system needs to be installed. As long as the plate wall thickness of the mounting frame 5 at the mounting hole matches the width dimension of the annular groove 21 in the axial direction of the tube body 1, the purpose of this application can be achieved.

[0081] In some embodiments of the present application, the mounting frame 5 is a sheet metal structure, the pump body 43 in the pump component 4 is detachably arranged on the mounting frame 5 by bolts, the second end of the pipeline structure is connected to the discharge pipeline 41 of the pump component 4 through the connecting sleeve section 13, and the second end of the pipeline structure is connected to the mounting hole on the mounting frame 5 through the elastic clamping portion 2, so that water can be transported from one side of the mounting frame 5 to the other side of the mounting frame 5, thereby realizing the drainage function of the drainage system.

[0082] In the above embodiment, the drainage system can be applied to any occasion where drainage is required, such as various construction sites, automobile air conditioners and household electrical appliances, etc. At this time, the mounting frame 5 can be a rigid structural member fixedly installed in various construction sites, automobile air conditioners and household electrical appliances, which is conducive to the deployment of the drainage system in various occasions.

[0083] See also Figures 1 to 10 According to a third aspect of an embodiment of the present application, there is provided an air-conditioning device, including the drainage system in the above-mentioned embodiment, and also including a water receiving pan (not shown in the figure). The water receiving pan can be used to receive condensed water or defrost water generated during the operation of the air-conditioning device. A suction pipeline 42 is provided on the pump member 4. The suction pipeline 42 is arranged corresponding to the water receiving pan, and is used to suck out the water in the water receiving pan to lower the water level in the water receiving pan, and then discharge the water to the outside of the air-conditioning device through the discharge pipeline 41 and the pipeline structure, so as to avoid the water level in the water receiving pan being too high and liquid leakage occurring inside the air-conditioning device.

[0084] In the above embodiment, the mounting frame 5 can be the outer shell of the air-conditioning equipment, the water receiving tray and the pump member 4 are arranged inside the air-conditioning equipment, and the first end of the pipe body 1 extends to the outside of the air-conditioning equipment through the mounting hole on the mounting frame 5 and is fixed by the elastic clamping part 2. The pump member 4 is powered by the pump body 43, and the condensed water in the water receiving tray is sucked into the water pump by the suction pipeline 42, and then discharged from the discharge pipeline 41, and finally the water is led out of the air-conditioning equipment through the pipeline structure.

[0085] See also Figures 1 to 10In some embodiments of the present application, the assembly process of the drainage system is as follows:

[0086] Step 1: Fix the pump component 4 on the mounting frame 5;

[0087] Step 2: sleeve the fixing member 6 onto the outside of the connecting sleeve section 13 or the transmission section 14, sleeve the connecting sleeve section 13 onto the discharge pipeline 41 of the pump member 4, and then sleeve the fixing member 6 onto the outside of the connecting sleeve section 13 and the discharge pipeline 41;

[0088] Step three: Extend the first end of the tube body 1 from the mounting hole on the mounting frame 5, so that the guide structure 23 of the elastic clamping part 2 contacts the inner wall of the mounting hole, and forcefully push the elastic clamping part 2 toward the mounting hole to cause the guide structure 23 and the limiting structure 22 to shrink and deform until the annular clamping groove 21 engages with the mounting hole on the mounting frame 5.

[0089] The elastic clamping portion 2 realizes elastic reset, the limiting structure 22 abuts against the inner surface of the mounting frame 5, and the large diameter end of the guide structure 23 abuts against the outer surface of the mounting frame 5, thereby fixing the first end of the tube body 1.

[0090] In the above assembly process, the order of step 2 and step 3 can be swapped, which is not limited here.
