[0010] A first limiting wall;

[0011] The second limiting wall is symmetrically arranged with the first limiting wall; the second end of the first limiting wall and / or the second limiting wall away from the first end of the first accommodating portion is provided with a clamping portion.

[0012] Beneficial effects: The pumping assembly can be confined in a specific installation space (first accommodating portion) by the symmetrically arranged first limiting wall and the second limiting wall, thereby ensuring installation reliability; and the clamping portion is provided to further improve connection reliability.

[0013] In an optional embodiment, the clamping portion includes:

[0014] A plurality of clamping ribs are vertically arranged on a side where the first limiting wall and the second limiting wall face each other.

[0015] Beneficial effect: When a buffer layer for reducing vibration and noise is provided between the pumping component and the mounting bracket, the buffer layer can be fixed by a clamping portion; the clamping portion includes a plurality of clamping ribs, which can increase the friction coefficient between the buffer layer and the mounting bracket and improve the connection reliability.

[0016] In an optional embodiment, the second accommodation portion includes:

[0017] A support portion, arranged at one end of the second accommodation portion close to the first accommodation portion, and a concave support groove is formed on the support portion;

[0018] A limiting ring is arranged at an end of the second accommodating portion away from the first accommodating portion.

[0019] Beneficial effects: The concave support groove can support the docking pipe, improving the connection reliability between the docking pipe and the pumping assembly; the limit ring can limit and guide the docking pipe away from one end of the first accommodating portion, thereby realizing a reliable connection between the docking pipe and the liquid storage container.

[0020] In an optional embodiment, the support body further includes:

[0021] The connection structure is arranged on the support body and is suitable for firmly assembling the support body carrying the pumping assembly to the mounting surface.

[0022] Beneficial effect: The bracket body is securely assembled to the mounting surface through the connecting structure, thereby realizing reliable assembly of the pumping component on the mounting surface.

[0023] In a second aspect, the present invention further provides a pumping device, comprising:

[0024] Pumping components;

[0025] In any of the above mounting brackets, the pumping assembly is disposed in the first accommodating portion.

[0026] Beneficial effect: Since the pumping device includes the mounting bracket of the present invention, it has the same technical effect as the mounting bracket, which will not be described in detail here.

[0027] In an optional embodiment, the pumping device further comprises:

[0028] a buffer layer, through which the pumping assembly is disposed in the first accommodation portion;

[0029] A docking pipe is connected to the pumping assembly; and the docking pipe is arranged in the second accommodating portion; the pumping assembly is indirectly in contact with the mounting bracket through the buffer layer and the docking pipe.

[0030] Beneficial effects: A buffer layer is provided between the pumping assembly and the first receiving part of the bracket body, which further reduces the propagation of vibration and noise generated during the operation of the pumping assembly and improves the user experience; the pumping assembly is docked with a liquid storage container such as a water tank through a docking pipe; the docking pipe is provided in the second receiving part of the bracket body and can be reliably assembled to the mounting surface together with the pumping assembly, and the docking reliability is high. The pumping assembly achieves indirect contact and cooperation with the mounting bracket through the buffer layer and the docking pipe. Compared with direct contact, indirect contact can effectively weaken the transmission of vibration and noise under the damping effect of the buffer layer, the change and interruption of the propagation path, the adjustment of the natural frequency of the system, and the isolation effect.

[0031] In an optional embodiment, the buffer layer includes:

[0032] A sponge pad is arranged between the pumping assembly and the mounting bracket.

[0038] In an optional implementation, the electrical device further includes:

[0039] A liquid storage container is connected to the pumping assembly through the docking pipeline.

[0040] Beneficial effects: the liquid storage container is connected to the pumping assembly through the docking pipe, and the pumping assembly and the docking pipe are securely installed together through the mounting bracket, with good durability and stability.

[0041] In an optional implementation, the electrical device further includes:

[0042] The sealing structure is arranged at the connection point between the butt pipe and the liquid storage container.

[0043] Beneficial effect: A sealing structure is provided at the joint between the liquid storage container and the docking pipe to prevent leakage.

[0044] In an optional embodiment, the sealing structure includes:

[0045] A first docking valve, comprising a first valve body and a first valve core;

[0046] The second docking valve comprises a second valve body and a second valve core; the second valve body comprises an inner ring and an outer ring, and a sealing ring groove is formed between the inner ring and the outer ring;

[0047] a first sealing member, mounted on the inner ring of the second valve body;

[0048] The second sealing member is installed on the outer ring of the second valve body.

[0049] Beneficial effects: By setting the first sealing member and the second sealing member at the joint of the first butt-joint valve and the second butt-joint valve, a double seal is formed, thereby improving the butt-joint reliability of the two butt-joint valves. 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 and the second sealing member are respectively installed on the inner ring and the outer ring of the second valve body, so as to form a first sealing barrier between the first valve body, the second valve body and the first sealing member, and to form a second sealing barrier between the first valve body, the second valve body and the second sealing member. The structure is simple and the reliability is high.

[0050] In an optional embodiment, the first docking valve and the second docking valve have an intermediate docking state and an in-place state in which the docking is completed; in the intermediate state, the first sealing member is in contact with the first valve body, and a first closed cavity is formed between the first valve body, the second valve body and the first sealing member; in the in-place state, the first docking valve and the second docking valve are connected, and a second closed cavity is formed between the first valve body, the second valve body and the second sealing member, thereby forming a double seal.

[0051] Beneficial effect: When the two docking parts are docked and connected, the first sealing part first contacts the first docking valve during the docking process, and forms a first closed cavity as a first sealing barrier between the first valve body, the second valve body and the first sealing part, 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 as a second sealing barrier is formed between the first valve body, the second valve body and the second sealing part, and under the double sealing action of the first sealing part and the second sealing part, the sealing effect is further enhanced to ensure that there is no water leakage after the first docking valve and the second docking valve are connected. Therefore, when the sealing structure of the present invention is applied to the docking point 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 docking point, thereby improving the reliability of the electrical equipment.

[0052] In an optional embodiment, the first sealing member comprises:

[0053] A first sealing ring, wherein the outer peripheral side of the inner ring is provided with an annular embedding groove, and the first sealing ring is sleeved in the annular embedding groove;

[0054] The sealing burr is formed on the periphery of the first sealing ring.

[0056] In an optional embodiment, the second sealing member includes:

[0057] A mounting portion, clamped and sleeved on the upper edge of the outer ring;

[0058] The sealing portion is formed by axially extending the mounting portion and is located in the sealing ring groove.

[0059] Beneficial effect: The second sealing member is clamped and sleeved on the upper edge of the outer ring of the second valve body through the installation portion, and is reliably connected to the second valve body to avoid falling out during the installation and matching process; the sealing portion extended by the installation portion can be sealed and matched with the first docking valve in the sealing ring groove, thereby forming a second sealing cavity, thereby improving the sealing reliability.

[0060] In an optional embodiment, the electrical device is a cooling fan, the pumping assembly includes a water pump, the liquid storage container includes a water tank, and the water pump is connected to the water tank via the docking pipe.

[0061] Beneficial effects: Since the cooling fan adopts the pipe connection structure of the present invention, the water pump and the docking pipe are reliably assembled through the mounting bracket, and the connection reliability between the water pump and the docking pipe and the water tank is high, thereby improving the durability and reliability of the cooling fan and improving user satisfaction.

[0062] In an optional embodiment, a damping structure is provided at the first end of the docking pipe connected to the water pump, and the damping structure is suitable for buffering and absorbing vibration energy of the water pump to prevent the vibration energy from being transmitted along the docking pipe.

[0063] Beneficial effect: A damping structure is set at the first end of the docking pipe close to the water pump, and the damping structure buffers and absorbs vibration energy to prevent the vibration energy from being transmitted along the docking pipe to the second end of the docking pipe, thereby reducing the propagation of vibration and noise generated during the operation of the water pump, improving the durability and reliability of electrical equipment, and improving user satisfaction.

[0064] In an optional implementation, the damping structure includes:

[0065] The vibration-damping cavity is arranged on the outer peripheral side of the butt-jointed pipe.

[0066] Beneficial effects: The setting of the cavity structure 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 a vibration-damping cavity has a simple structure.

[0067] In an optional embodiment, the first end of the docking pipe includes:

[0068] an inner tube adapted to be connected to the vibration source;

[0069] An outer tube is arranged at intervals on the outer peripheral side of the inner tube;

[0070] A groove is formed between the inner tube and the outer tube to constitute the vibration-damping cavity.

[0071] 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.

[0165] The mounting portion 41 is clamped and sleeved on the upper edge of the outer ring;

[0166] The sealing portion 42 is formed by axially extending the mounting portion 41 and is located in the sealing ring groove.

[0167] The second sealing member 4 is clamped and sleeved on the upper edge of the outer ring of the second valve body 21 through the mounting portion 41, and is reliably connected to the second valve body 21 to avoid falling out during the installation process; the sealing portion 42 extended from the mounting portion 41 can be sealed and matched with the first docking valve 1 in the sealing ring groove, thereby forming a second sealing cavity 501, thereby improving the sealing reliability.

[0168] In some embodiments, the electrical device is a cooling fan, the pumping assembly 300 includes a water pump, the liquid storage container includes a water tank, and the water pump and the water tank are connected via a docking pipe 200.

[0169] Since the cooling fan adopts the pipe connection structure 601 of the present invention, the water pump and the docking pipe 200 are reliably assembled through the mounting bracket 600, and the connection reliability between the water pump, the docking pipe 200 and the water tank is high, thereby improving the durability and reliability of the cooling fan and improving user satisfaction.

[0170] In some embodiments, the docking duct 200 comprises a flexible duct.

[0171] Compared with the use of rigid pipes, the use of flexible pipes as the docking pipes 200 can greatly reduce vibration and noise, improve user experience, and extend the service life of the equipment.

[0172] 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.

[0173] In some embodiments, a damping structure is disposed at the first end of the docking pipe 200 connected to the water pump, and the damping structure is suitable for buffering the vibration energy of the adsorption water pump to prevent the vibration energy from being transmitted along the docking pipe 200 .

[0174] A damping structure is provided at the first end of the docking pipe 200 close to the water pump, and the vibration energy is buffered and absorbed by the damping structure to prevent the vibration energy from being transmitted along the docking pipe 200 to the second end of the docking pipe 200, thereby reducing the propagation of vibration and noise generated during the operation of the water pump, improving the durability and reliability of the electrical equipment, and improving user satisfaction.

[0175] In some embodiments, Fig. 9 As shown, the damping structure includes:

[0176] The vibration-damping cavity 500 is disposed on the outer peripheral side of the docking pipe 200 .

[0177] The setting of the cavity structure 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 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 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 vibration reduction cavity 500 is used, which has a simple structure.

[0178] In some embodiments, the first end of the docking pipe 200 includes:

[0179] The inner tube 201 is suitable for connecting to a vibration source;

[0180] The outer tube 202 is disposed at intervals on the outer circumference of the inner tube 201;

[0181] The groove is formed between the inner tube 201 and the outer tube 202 to form a vibration-damping cavity 500 .

[0182] 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.

[0183] 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.

[0184] In some embodiments, the docking pipeline 200 further includes:

[0185] 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 .

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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 vibration reduction and noise reduction effect is significant.

[0191] 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.

[0192] 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.
