Description

Technical Field

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

[0002] In air conditioning systems, hydraulic systems, water treatment systems and chemical production, it is common to encounter the docking of liquid storage containers with pipelines, the docking of liquid storage containers with each other, or the docking of liquid storage containers with pumping devices, so as to facilitate the transportation and circulation of media or raw materials.

[0003] The joints of the above devices are generally sealed with seals. Due to the wear and aging of the seals themselves, or the influence of installation and assembly deviations and the operating environment, the joints are prone to water leakage. Taking the cooling fan as an example, when a water pump is installed outside the water tank, the joints between the water tank and the water pump are prone to water leakage, affecting the reliability of the cooling fan. Summary of the invention

[0004] In view of this, the present invention provides a sealing structure, a fluid device and an electrical device to solve the problem of water leakage at the joints between a liquid storage container and a pipeline, other liquid storage containers or a pumping device.

[0005] In a first aspect, the present invention provides a sealing structure, comprising:

[0006] A first docking valve, comprising a first valve body and a first valve core;

[0007] 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;

[0008] a first sealing member, mounted on the inner ring of the second valve body;

[0009] The second sealing member is installed on the outer ring of the second valve body.

[0010] 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.

[0011] 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.

[0012] 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 pushed open; 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.

[0013] In an optional embodiment, the first sealing member comprises:

[0014] 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;

[0015] The sealing burr is formed on the periphery of the first sealing ring.

[0016] Beneficial effect: the first sealing ring can be reliably installed on the outer peripheral side of the inner ring of the second valve body through the annular groove, and when the first sealing ring contacts the first docking valve, the sealing burr can block the fitting gap, further improving the sealing effect.

[0017] In an optional embodiment, the second sealing member includes:

[0018] A mounting portion, clamped and sleeved on the upper edge of the outer ring;

[0019] The sealing portion is formed by axially extending the mounting portion and is located in the sealing ring groove.

[0020] 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.

[0021] In a second aspect, the present invention further provides a fluid device, comprising:

[0022] a first docking member;

[0023] a second docking piece, the second docking piece being connected to the first docking piece through a docking pipe;

[0024] According to the sealing structure described in any one of the above items; the first docking valve is installed at the bottom end of the first docking piece, and the second docking valve is installed at the top end of the docking pipe. The first docking piece and the second docking piece are double-sealed and assembled through the sealing structure.

[0025] Beneficial effect: Since the fluid device includes the sealing structure of the present invention, it has the same technical effect as the sealing structure, which will not be described in detail here.

[0026] In an optional embodiment, the first docking member is a liquid storage container, and the second docking member is a pumping device.

[0027] Beneficial effects: The liquid storage container and the pumping device are connected through a docking pipe, and a double sealing connection is achieved through two docking valves, thereby avoiding water leakage at the docking point between the liquid storage container and the pumping device, achieving a good sealing effect and improving the user experience.

[0028] In a third aspect, the present invention further provides an electrical device, comprising any of the fluid devices described above.

[0029] Beneficial effect: Since the electrical equipment includes the fluid device of the present invention, it has the same technical effect as the fluid device, which will not be described in detail here.

[0030] In an optional implementation, the electrical device is a cooling fan, and the cooling fan comprises:

[0031] body;

[0032] Water tank;

[0033] A water pump is installed on the fuselage; the water pump is connected to the water tank through the docking pipe.

[0034] Beneficial effect: the water pump of the cooling fan is installed on the fuselage, which is more convenient to take and disassemble the water tank than installing it on the water tank, but it is also prone to water leakage when taking the water tank. The present invention provides two docking valves at the connection between the water tank and the docking pipe, and realizes double sealing through two sealing members. During the docking process, the first sealing cavity is used to avoid water tank leakage before conduction. After the docking is completed, the two seals of the first sealing cavity and the second sealing cavity are used to improve the sealing reliability after the water flow channel is connected.

[0035] In an optional embodiment, the docking pipe includes a flexible pipe.

[0036] Beneficial effects: Compared with rigid pipes, the use of flexible pipes as docking pipes can greatly reduce vibration and noise, improve user experience, and extend the service life of the equipment.

[0037] 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.

[0038] 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 generated during the operation of the water pump, reducing noise, improving equipment durability and reliability, and improving user satisfaction.

[0039] In an optional implementation, the damping structure includes:

[0040] The vibration-damping cavity is arranged on the outer peripheral side of the butt-jointed pipe.

[0041] 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.

[0042] In an optional embodiment, the first end of the docking pipe includes:

[0043] an inner pipe connected to the water pump;

[0044] An outer tube is arranged at intervals on the outer peripheral side of the inner tube;

[0045] A groove is formed between the inner tube and the outer tube to constitute the vibration-damping cavity.

[0046] 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.

[0047] In an optional embodiment, the docking pipeline further includes:

[0048] The partition ribs are arranged between the inner tube and the outer tube to divide the vibration-damping cavity into a plurality of cavities.

[0049] 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.

[0050] In an optional implementation, the electrical device further includes:

[0051] A mounting bracket, through which the water pump is mounted on the fuselage.

[0052] Beneficial effect: The water pump is installed on the machine body through the mounting bracket, ensuring the stability and durability of the electrical equipment.

[0053] In an optional embodiment, the mounting bracket includes a bracket body, and the bracket body includes:

[0054] A first accommodating portion, adapted to accommodate a water pump;

[0055] The second accommodating portion is connected to the first end of the first accommodating portion and is suitable for supporting a docking pipe connected to the water pump.

[0056] Beneficial effects: The pumping assembly is arranged in the first accommodating part of the bracket body, and the docking pipe is arranged in the second accommodating part of the bracket body. The pumping assembly and the docking pipe connected thereto can be firmly fixed by the mounting bracket at the same time, thereby improving the connection reliability of the pumping device and improving the durability and stability of long-term use. Even when the pumping assembly is placed outside the liquid storage container, the durability and stability of the equipment can still be ensured.

[0057] In an optional embodiment, the first accommodation portion includes:

[0058] A first limiting wall;

[0059] 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.

[0060] 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.

[0061] In an optional embodiment, the clamping portion includes:

[0062] A plurality of clamping ribs are vertically arranged on a side where the first limiting wall and the second limiting wall face each other.

[0063] Beneficial effect: The clamping portion includes a plurality of clamping ribs, which can increase the friction coefficient between the pumping component and the mounting bracket and improve the connection reliability.

[0064] In an optional embodiment, the second accommodation portion includes:

[0065] 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;

[0066] A limiting ring is arranged at an end of the second accommodating portion away from the first accommodating portion.

[0067] 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.

[0068] In an optional embodiment, the support body further includes:

[0069] The connection structure is arranged on the support body and is suitable for firmly assembling the support body carrying the water pump to the fuselage.

[0070] 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0106] In the description of the invention, it should be noted that, unless otherwise specified, the meaning of "plurality" is two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0107] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0108] In the related art, the water pump of the cooling fan is usually installed on the water tank, which makes it extremely inconvenient for users to take the water tank and is not convenient for maintenance, affecting the water quality and heat dissipation. If the water pump is externally installed, there is a problem of water leakage at the joint: the water pump will vibrate during operation, and the water in the water tank will also have a certain impact and friction on the seal. After long-term use, the single seal will gradually age, reduce elasticity, and reduce sealing performance. At the same time, the relative movement between the water pump shaft and the seal will also cause the seal to wear and gap, so that water can easily leak out, which will not only cause a waste of water resources, but also may damage other components of the cooling fan, and even cause electrical failures, affecting the user experience.

[0109] In addition, the external water pump will generate vibrations during operation. If it is not installed firmly, the vibrations will be transmitted to the surrounding environment, generating noise, affecting the user experience. It may also cause the fixing parts of the water pump to loosen, further affecting its stability. The connection between the water pump and the pipeline usually adopts a rigid connection. This connection method further increases the transmission of vibration and noise, which not only affects the user experience, but may also cause damage to the equipment. Although some prior arts have attempted to use soft materials to reduce vibrations, the effect is not significant, and the durability and stability of long-term use need to be improved. In view of this, the present invention is proposed.

[0110] Combine the following Figures 1 to 12 , describing an embodiment of the present invention.

[0111] According to an embodiment of the present invention, on the one hand, Figure 1 and Figure 3 As shown, a sealing structure is provided, comprising:

[0112] The first docking valve 1 comprises a first valve body 11 and a first valve core 12;

[0113] 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;

[0114] A first sealing member 3 is mounted on the inner ring of the second valve body 21;

[0115] The second sealing member 4 is mounted on the outer ring of the second valve body 21 .

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In some embodiments, Figure 2 and Figure 4 As shown, the first sealing member 3 comprises:

[0120] 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;

[0121] The sealing burr 32 is formed on the periphery of the first sealing ring 31 .

[0122] 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.

[0123] In some embodiments, Figure 2 and Figure 4 As shown, the second sealing member 4 comprises:

[0124] The mounting portion 41 is clamped and sleeved on the upper edge of the outer ring;

[0125] The sealing portion 42 is formed by axially extending the mounting portion 41 and is located in the sealing ring groove.

[0126] 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 closed cavity 20, thereby improving the sealing reliability.

[0127] According to an embodiment of the present invention, on the other hand, a fluid device is provided, comprising:

[0128] a first docking member;

[0129] A second docking piece, the second docking piece is connected to the first docking piece through a docking pipe 200;

[0130] Sealing structure; the first docking valve 1 is installed at the bottom end of the first docking member, and the second docking valve 2 is installed at the top end of the docking pipe 200. The first docking member and the second docking member are assembled in a double seal through the sealing structure.

[0131] Since the fluid device includes the sealing structure of the present invention, it has the same technical effect as the sealing structure, which will not be described in detail here.

[0132] In some embodiments, the first docking component is a liquid storage container and the second docking component is a pumping device.

[0133] The liquid storage container and the pumping device are connected via a docking pipe 200, and a double sealing connection is achieved through two docking valves to avoid water leakage at the docking point between the liquid storage container and the pumping device. The sealing effect is good and the user experience is improved.

[0134] According to another aspect of an embodiment of the present invention, an electrical device is provided, including a fluid device.

[0135] Since the electrical equipment includes the fluid device of the present invention, it has the same technical effects as the fluid device, which will not be described in detail here.

[0136] In some embodiments, the electrical device is a cooling fan, and the cooling fan includes:

[0137] body;

[0138] Water tank;

[0139] The water pump is installed on the fuselage; the water pump is connected to the water tank through a docking pipe 200.

[0140] The water pump of the cooling fan is installed on the fuselage. Compared with the method of installing it on the water tank, it is more convenient to take and disassemble the water tank, but it is also prone to water leakage when taking the water tank. The present invention sets two docking valves at the connection between the water tank and the docking pipe 200, and realizes double sealing through two seals. During the docking process, the first closed cavity 10 is used to avoid water tank leakage before conduction. After the docking is completed, the two seals of the first closed cavity 10 and the second closed cavity 20 are used to improve the sealing reliability after the water flow channel is connected.

[0141] In some embodiments, the docking duct 200 comprises a flexible duct.

[0142] 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.

[0143] 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.

[0144] 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 .

[0145] 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 generated during the operation of the water pump, reducing noise, improving equipment durability and reliability, and improving user satisfaction.

[0146] In some embodiments, Figure 5 and Figure 6 As shown, the damping structure includes:

[0147] The vibration-damping cavity 500 is disposed on the outer peripheral side of the docking pipe 200 .

[0148] 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.

[0149] In some embodiments, Figure 6 and Fig.10 As shown, the first end of the docking pipe 200 includes:

[0150] The inner tube 201 is connected to the water pump;

[0151] The outer tube 202 is disposed at intervals on the outer circumference of the inner tube 201;

[0152] The groove is formed between the inner tube 201 and the outer tube 202 to form a vibration-damping cavity 500 .

[0153] 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.

[0154] 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.

[0155] In some embodiments, the docking pipeline 200 further includes:

[0156] 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 .

[0157] 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, on the one hand, increase the damping resistance: the presence of a plurality of separation ribs 203 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: 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.

[0158] 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.
