Description

Technical Field

[0001] The present invention relates to the technical field of fluid machinery, and in particular to a pipeline connection structure, a pumping device and electrical equipment. Background Art

[0002] The connection between the pumping device and the pipe of the air conditioning equipment is generally rigidly connected. Although this method has good durability, the vibration and noise generated by the pumping device when it is working are also more easily transmitted. Taking the cooling fan as an example, the connection between the water pump and the pipe is rigidly connected, and the water pump is prone to vibration and noise when it is running. The vibration and noise of the equipment will give users a bad experience and affect user satisfaction. Summary of the invention

[0003] In view of this, the present invention provides a pipeline connection structure, a pumping device and an electrical device to solve the problem that the connection method between the pumping device and the pipeline causes vibration and noise to be easily transmitted, causing a bad experience for users.

[0004] In a first aspect, the present invention provides a pipeline connection structure, comprising:

[0005] A docking pipe, comprising a first end and a second end, wherein a fluid channel is formed between the first end and the second end;

[0006] A damping structure is arranged at the first end of the docking pipe close to the vibration source to buffer and absorb vibration energy and prevent the vibration energy from being transmitted to the second end along the docking pipe; the damping structure includes a vibration-damping cavity arranged on the outer peripheral side of the docking pipe.

[0007] Beneficial effects: a damping structure is arranged at the first end of the docking pipe close to the vibration source, and the vibration energy is buffered and absorbed by the damping structure to prevent the vibration energy from being transmitted along the docking pipe to the second end of the docking pipe; after the pumping device is provided with the pipeline connection structure, the propagation of vibration generated during the operation of the pumping device can be reduced, noise can be reduced, the durability and reliability of the equipment can be improved, and user satisfaction can be improved.

[0008] The use of vibration-damping cavities plays a role in absorbing vibration and noise. The air or other filling medium inside the cavity structure has friction and viscosity with the wall of the structure, which can dissipate vibration energy, which is equivalent to increasing the damping of the structure; when excited by vibration, the cavity structure can disperse the vibration energy to a larger area; due to the existence of the cavity, the force distribution of the structure is more uniform, and it can also avoid strong vibration caused by local stress concentration; part of the vibration energy can also be transferred to the kinetic energy or internal energy of the medium through interaction with the medium in the cavity. When sound waves are transmitted into the cavity structure, reflection, refraction and interference will occur in the cavity. The incident sound wave and the reflected sound wave will interfere with each other and cancel each other out, thereby reducing the propagation and radiation of sound, thereby reducing noise. In addition, the use of vibration-damping cavities has a simple structure.

[0009] In an optional embodiment, the first end of the docking pipe includes:

[0010] an inner tube adapted to be connected to the vibration source;

[0011] An outer tube is arranged at intervals on the outer peripheral side of the inner tube;

[0012] A groove is formed between the inner tube and the outer tube to constitute the vibration-damping cavity.

[0013] Beneficial effect: The first end of the docking pipe includes an inner pipe and an outer pipe, a groove serving as a vibration-damping cavity is formed between the inner pipe and the outer pipe, the docking pipe is connected to the vibration source through the inner pipe, and the groove is formed on the periphery of the connection with the vibration source, which can effectively absorb vibration and noise.

[0014] In an optional embodiment, the docking pipeline further includes:

[0015] The partition ribs are arranged between the inner tube and the outer tube to divide the vibration-damping cavity into a plurality of cavities.

[0016] Beneficial effects: The vibration reduction cavity is divided into multiple cavities by separating ribs, which improves the vibration reduction effect. Dividing the vibration reduction cavity into multiple small cavities can increase the damping resistance on the one hand: the presence of multiple ribs increases the resistance, thereby improving the energy consumption efficiency, and helps to absorb and convert vibration energy more effectively; on the other hand, it can disperse the vibration transmission path: multiple independent small chambers can change the propagation mode of vibration waves, so that the vibration energy is reflected and refracted multiple times, which ultimately leads to faster energy attenuation and reduces the vibration intensity transmitted to other components; on the other hand, the reasonable rib layout not only enhances the structural stability, but also can adjust the stiffness distribution of each part according to actual needs to achieve better vibration reduction performance.

[0017] In an optional embodiment, the docking pipeline includes:

[0018] A flexible pipe, the docking pipe is connected to the vibration source through the flexible pipe.

[0019] Beneficial effect: Compared with the rigid connection method, the flexible pipe is connected to the vibration source, which absorbs vibration through deformation and further improves the vibration reduction and noise reduction effect.

[0020] In a second aspect, the present invention further provides a pumping device, comprising:

[0021] Pumping components;

[0022] In any of the above described pipeline connection structures, the docking pipeline is installed on the pumping component.

[0023] Beneficial effects: Since the pumping device adopts the pipe connection structure of the present invention, a damping structure is arranged at one end of the docking pipe close to the pumping component, which reduces the propagation of vibration generated during the operation of the pumping component, reduces the transmission of noise, improves the durability and reliability of the pumping device, and improves user satisfaction.

[0024] In an optional embodiment, the pumping assembly includes a water pump, and the docking pipe is detachably mounted on the water pump.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0107] Combine the following Figures 1 to 12 , describing an embodiment of the present invention.

[0108] According to an embodiment of the present invention, on the one hand, Figure 1-Figure 2 As shown, a pipeline connection structure 601 is provided, comprising:

[0109] The docking pipe 200 comprises a first end and a second end, and a fluid channel is formed between the first end and the second end;

[0110] The damping structure is arranged at the first end of the docking pipe 200 close to the vibration source to buffer and absorb the vibration energy and prevent the vibration energy from being transmitted to the second end along the docking pipe 200; the damping structure includes a vibration-damping cavity 500 arranged on the outer peripheral side of the docking pipe 200.

[0111] A damping structure is provided at the first end of the docking pipe 200 close to the vibration source, and the damping structure is used to buffer and absorb the vibration energy, so as to prevent the vibration energy from being transmitted along the docking pipe 200 to the second end of the docking pipe 200; after the pumping device is provided with the pipeline connection structure 601, the propagation of the vibration generated during the operation of the pumping device can be reduced, the noise can be reduced, the durability and reliability of the equipment can be improved, and the user satisfaction can be improved. The setting of the vibration-damping cavity 500 plays the role of absorbing vibration and noise. The air or other filling medium inside the cavity structure has friction and viscosity with the wall surface of the structure, which can dissipate the vibration energy, which is equivalent to increasing the damping of the structure; when subjected to vibration excitation, the cavity structure can disperse the vibration energy to a larger area; due to the existence of the cavity, the force distribution of the structure is more uniform, and the strong vibration caused by local stress concentration can be avoided; part of the vibration energy can also be transferred to the kinetic energy or internal energy of the medium through the interaction with the medium in the cavity. When sound waves enter the cavity structure, reflection, refraction and interference will occur in the cavity. The incident sound waves and the reflected sound waves will interfere with each other and cancel each other out, thereby reducing the propagation and radiation of sound and thus reducing noise. In addition, the vibration reduction cavity 500 has a simple structure.

[0112] In some embodiments, Figure 2 As shown, the first end of the docking pipe 200 includes:

[0113] The inner tube 201 is suitable for connecting to a vibration source;

[0114] The outer tube 202 is disposed at intervals on the outer circumference of the inner tube 201;

[0115] The groove is formed between the inner tube 201 and the outer tube 202 to form a vibration-damping cavity 500 .

[0116] The first end of the docking pipe 200 includes an inner pipe 201 and an outer pipe 202. A groove serving as a vibration-damping cavity 500 is formed between the inner pipe 201 and the outer pipe 202. The docking pipe 200 is connected to the vibration source through the inner pipe 201. The groove is formed on the periphery of the connection with the vibration source, which can effectively absorb vibration and noise.

[0117] Specifically, the width of the groove is generally greater than 1 mm, and the depth of the groove is generally greater than 5 mm. The maximum limits of the width and depth of the groove are not specifically limited here. In actual applications, the width of the groove can be designed according to the diameter and length of the docking pipe 200, and the depth of the groove can be reasonably selected according to the layout space size of the docking pipe 200 and the vibration source. In addition, the material properties of the docking pipe 200 must also be comprehensively considered.

[0118] In some embodiments, the docking pipeline 200 further includes:

[0119] The partition rib 203 is disposed between the inner tube 201 and the outer tube 202 to divide the vibration-damping cavity 500 into a plurality of cavities 501 .

[0120] The vibration reduction cavity 500 is divided into a plurality of cavities 501 by the separation ribs 203 to improve the vibration reduction effect. Dividing the vibration reduction cavity 500 into a plurality of small cavities 501 can increase the damping resistance on the one hand: the presence of a plurality of separation ribs 203 increases the resistance, thereby improving the energy consumption efficiency, and helps to absorb and convert the vibration energy more effectively; on the other hand, it can disperse the vibration transmission path: a plurality of independent small cavities 501 can change the propagation mode of the vibration wave, so that the vibration energy is reflected and refracted multiple times, which eventually leads to faster energy attenuation and reduces the vibration intensity transmitted to other components; on the other hand, the reasonable layout of the separation ribs 203 not only enhances the structural stability, but also can adjust the stiffness distribution of each part according to actual needs to achieve better vibration reduction performance.

[0121] It should be noted that, in some embodiments, Fig.11 As shown, the separation ribs 203 may be a plurality of ribs disposed between the inner tube 201 and the outer tube 202 and arranged axially along the vibration-damping cavity 500, and the plurality of ribs divide the vibration-damping cavity 500 into a plurality of cavities 501 extending axially along the docking pipe 200. In other embodiments, the separation ribs 203 may also be honeycomb walls, and the honeycomb walls divide the vibration-damping cavity 500 into honeycomb chambers.

[0122] In some embodiments, the docking duct 200 includes:

[0123] The flexible pipe, the docking pipe 200 is connected to the vibration source through the flexible pipe.

[0124] Compared with the rigid connection method, the flexible pipe is connected to the vibration source, which absorbs the vibration through deformation, further improving the vibration reduction and noise reduction effects.

[0125] It should be noted that the docking pipe 200 may be made entirely of a flexible material, or at least the portion of the docking pipe 200 connected to the vibration source may be made of a flexible pipe.

[0126] According to an embodiment of the present invention, on the other hand, a pumping device is provided, comprising:

[0127] Pumping assembly 300;

[0128] The pipeline connection structure 601 , the docking pipeline 200 is installed on the pumping assembly 300 .

[0129] Since the pumping device adopts the pipe connection structure 601 of the present invention, a damping structure is set at one end of the docking pipe 200 close to the pumping component 300, which reduces the propagation of vibration generated during the operation of the pumping component 300, reduces the transmission of noise, improves the durability and reliability of the pumping device, and improves user satisfaction.

[0130] In some embodiments, the pumping assembly 300 includes a water pump, and the docking pipe 200 is detachably mounted on the water pump.

[0131] The docking pipe 200 and the water pump are connected in a detachable manner to facilitate maintenance and replacement operations.

[0132] According to an embodiment of the present invention, on the other hand, there is provided an electrical device, including:

[0133] body;

[0134] liquid storage container;

[0135] The pumping device, the pumping assembly 300 is connected to the liquid storage container through the docking pipe 200.

[0136] Since the electrical equipment includes the pumping device of the present invention, it has the same technical effect as the pumping device, which will not be described in detail here.

[0137] In some embodiments, Figure 3-Figure 6 As shown, the electrical equipment also includes:

[0138] The sealing structure is arranged at the connection between the butt pipe 200 and the liquid storage container.

[0139] A sealing structure is provided at the joint between the liquid storage container and the docking pipe 200 to prevent water leakage.

[0140] In some embodiments, Figure 4 and Figure 6 As shown, the sealing structure includes:

[0141] The first docking valve 1 includes a first valve body 11 and a first valve core 12, see Figure 7 ;

[0142] The second docking valve 2 comprises a second valve body 21 and a second valve core 22; the second valve body 21 comprises an inner ring and an outer ring, and a sealing ring groove is formed between the inner ring and the outer ring;

[0143] A first sealing member 3 is mounted on the inner ring of the second valve body 21;

[0144] The second sealing member 4 is mounted on the outer ring of the second valve body 21 .

[0145] The first sealing member 3 and the second sealing member 4 are arranged at the joint of the first butt-joint valve 1 and the second butt-joint valve 2 to form a double seal, thereby improving the butt-joint reliability of the first butt-joint valve 1 and the second butt-joint valve 2. When the sealing structure of the present invention is applied to the joint between the liquid storage container and the pipeline, between the liquid storage container, or between the liquid storage container and the pumping device, it can avoid the occurrence of water leakage at the joint, thereby improving the reliability of the fluid device and the electrical equipment. The first sealing member 3 and the second sealing member 4 are respectively installed on the inner ring and the outer ring of the second valve body 21, so as to form a first sealing barrier between the first valve body 11, the second valve body 21 and the first sealing member 3, and a second sealing barrier between the first valve body 11, the second valve body 21 and the second sealing member 4, which has a simple structure and high reliability.

[0146] In some embodiments, the first docking valve 1 and the second docking valve 2 have an intermediate docking state and an in-place state in which the docking is completed; in the intermediate state, the first sealing member 3 is in contact with the first valve body 11, and a first closed cavity 10 is formed between the first valve body 11, the second valve body 21 and the first sealing member 3; in the in-place state, the first docking valve 1 is connected to the second docking valve 2, and a second closed cavity 20 is formed between the first valve body 11, the second valve body 21 and the second sealing member 4, constituting a double seal.

[0147] When the two docking parts are docked and connected, the first sealing member 3 first contacts the first docking valve 1 during the docking process, and forms a first closed cavity 10 as a first sealing barrier between the first valve body 11, the second valve body 21 and the first sealing member 3, ensuring that there is no water leakage before the valve core is opened; and when the two docking parts are docked, a second closed cavity 20 as a second sealing barrier is formed between the first valve body 11, the second valve body 21 and the second sealing member 4, and under the double sealing action of the first sealing member 3 and the second sealing member 4, the sealing effect is further enhanced to ensure that there is no water leakage after the first docking valve 1 and the second docking valve 2 are connected. Therefore, when the sealing structure of the present invention is applied to the docking of the liquid storage container and the pipeline, between the liquid storage container, or between the liquid storage container and the pumping device, it can avoid the occurrence of water leakage at the docking, thereby improving the reliability of the electrical equipment.

[0148] In some embodiments, Figure 4 and Figure 6 As shown, the first sealing member 3 comprises:

[0149] The first sealing ring 31 has an annular embedding groove on the outer circumference of the inner ring, and the first sealing ring 31 is sleeved in the annular embedding groove;

[0150] The sealing burr 32 is formed on the periphery of the first sealing ring 31 .

[0151] The first sealing ring 31 can be reliably installed on the outer peripheral side of the inner ring of the second valve body 21 through the annular groove. When the first sealing ring 31 contacts the first docking valve 1, the sealing burr 32 can block the fitting gap to further improve the sealing effect.

[0152] In some embodiments, Figure 4 and Figure 6 As shown, the second sealing member 4 comprises:

[0166] like Fig.12 As shown, the second limiting wall 620 and the first limiting wall 610 are symmetrically arranged along the perpendicular bisector E of the length direction of the first accommodation portion. Of course, in other embodiments, they can also be symmetrically arranged along other symmetry planes, mainly based on the direction of the installation surface of the mounting bracket 600 and the layout space.

[0177] The buffer layer 400 , the pumping assembly 300 is disposed in the first accommodation portion through the buffer layer 400 .

[0178] The docking pipe 200 is connected to the pumping assembly 300 ; and the docking pipe 200 is disposed in the second accommodation portion.

[0179] The pumping assembly 300 is docked with a liquid storage container such as a water tank through a docking pipe 200; the docking pipe 200 is arranged in the second accommodating portion of the bracket body, and can be reliably assembled to the installation surface together with the pumping assembly 300, and the docking reliability is high.

[0180] A buffer layer 400 is provided between the pumping assembly 300 and the first accommodating portion of the bracket body to further reduce the propagation of vibration and noise generated during the operation of the pumping assembly 300 and enhance the user experience.

[0181] When a buffer layer 400 for reducing vibration and noise is disposed between the pumping assembly 300 and the mounting bracket 600 , the buffer layer 400 may be fixed by the clamping portion 602 .

[0182] In some embodiments, the buffer layer 400 includes:

[0183] The sponge pad is disposed between the pumping assembly 300 and the mounting bracket 600 .

[0184] Sponge pads are used to reduce vibration and noise, and are easy to install and replace with low cost.

[0185] In some embodiments, the electrical device is a cooling fan.

[0186] Since the cooling fan adopts the pipe connection structure 601 of the present invention, a damping structure is set at one end of the docking pipe 200 close to the water pump to reduce the propagation of vibration generated during the operation of the water pump, reduce the transmission of noise, improve the durability and reliability of the water pump, and improve user satisfaction.

[0187] like Figure 1-Figure 10 As shown, a specific embodiment of the present invention provides a cooling fan, which adopts a method of placing a water pump outside the water tank. The water pump is installed on the cooling fan body instead of the traditional water tank, which is convenient for users to take the water tank. The water pump is connected to the second docking valve 2 through the docking pipe 200 and installed at a predetermined position on the cooling fan body to ensure that it is stable and has good sealing. The first docking valve 1 is installed on the water tank to ensure that it is stable and has good sealing. The first docking valve 1 and the second docking valve 2 both include a valve body, a valve core and a spring. The first sealing member 3 (first sealing ring 31) and the second sealing member 4 (second sealing ring) are assembled at the second docking valve 2 for double sealing.

[0188] When the user installs the water tank on the body, the first docking valve 1 and the second docking valve 2 gradually approach and dock with each other. During the docking process, the first sealing member 3 first contacts the first docking valve 1 during the assembly process to form a first closed cavity 10 to ensure that there is no water leakage before the valve core assembly is opened. As the water tank is further installed in place, the valve core assemblies are lifted up and opened, and the water path is opened. At the same time, the second sealing member 4 forms a second closed cavity 20 with the first docking valve 1 to ensure the sealing of the entire connecting channel. The water in the water tank flows through the first docking valve 1 above to the second docking valve 2 below, and is then pumped by the water pump to the wet curtain to complete the cooling process. The double sealing design effectively prevents water leakage between the two docking valves, improves the reliability and durability of the product, reduces water leakage problems during assembly, and simplifies the user's operating steps.

[0189] The water pump of the cooling fan is fixed to the fuselage through the mounting bracket 600, and a sponge pad is set between the water pump and the mounting bracket 600. According to the size and weight of the water pump, a stable bracket is designed. The water pump bracket does not directly contact the water pump. The water pump is fixed to the fuselage through the silicone pipe and sponge to indirectly contact the water pump, thereby improving the vibration reduction performance. At the end of the water pump away from the docking pipe 200, a sponge material with sound absorption and shock absorption functions is used to tightly wrap it. The mounting bracket 600 should be made of rust-proof and high-strength materials to ensure long-term stability. The docking pipe 200 uses a silicone pipe, and high-quality silicone materials are selected to make the pipe to ensure that it has good elasticity and durability. The end of the silicone pipe close to the water pump is designed as a hollow groove to increase elasticity and reduce vibration transmission. Connect the silicone pipe between the water pump and the second docking valve 2 to ensure that the connection is tight and leak-free. Subsequently, the water pump is fixed to the fuselage with the mounting bracket 600, and it is confirmed whether the parts are installed in place to ensure that the system operates normally and the shock and noise reduction effect is significant.

[0190] The present invention is applicable to various cooling fan products, and is particularly advantageous in scenarios where the water tank needs to be frequently replaced or cleaned. Through the external water pump and double sealing design, the present invention can significantly improve the market competitiveness of cooling fans and bring users a more convenient and reliable use experience.

[0191] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
