[0030] In an alternative embodiment, the electric appliance is a cooling fan, which comprises:

[0031] A machine body;

[0032] A water tank;

[0033] A water pump installed on the machine body; the water pump and the water tank are connected through the connecting pipe.

[0034] Beneficial effect: The water pump of the cooling fan is installed on the machine body, which is more convenient for taking and disassembling the water tank than the way of installing on the water tank, but it is easy to leak water when taking the water tank.

In the connection process, the first sealing cavity avoids water leakage before the water flow channel is connected, and the two seals of the first sealing cavity and the second sealing cavity improve the sealing reliability of the water flow channel after being connected.

[0035] In an alternative embodiment, the connecting pipe comprises a flexible pipe.

[0036] Beneficial effects: compared with the rigid pipe, the flexible pipe as the connecting pipe greatly reduces the vibration and noise, improves the user experience, and prolongs the service life of the equipment.

[0037] In an optional embodiment, the first end of the connecting pipe connected to the water pump is provided with a damping structure, which is suitable for buffering and absorbing the vibration energy of the water pump to avoid the transmission of the vibration energy along the connecting pipe.

[0039] In an optional embodiment, the damping structure comprises:

[0040] a damping cavity arranged on the outer periphery of the connecting pipe.

[0041] Beneficial effects: the cavity structure plays a role in consuming and absorbing vibration and noise. The air or other filling medium inside the cavity structure has friction and viscous effect with the structure wall, which can dissipate vibration energy, 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 stress distribution of the structure is more uniform, and local stress concentration caused by strong vibration can also 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 the sound wave enters the cavity structure, reflection, refraction and interference phenomena will occur in the cavity, and the incident sound wave and the reflected sound wave will interfere with each other and cancel out, thereby reducing the propagation and radiation of sound, and thus reducing noise. Moreover, the damping cavity has a simple structure.

The connecting 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 alternative embodiment, the docking pipe further comprises:

[0048] A partition rib is arranged between the inner pipe and the outer pipe to divide the damping cavity into multiple cavities.

[0049] Beneficial effect: The damping cavity is divided into multiple cavities by the partition rib, improving the damping effect. Dividing the damping 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 helping to more effectively absorb and convert vibration energy; on the other hand, it can disperse the vibration transmission path: multiple independent small cavities can change the propagation mode of the vibration wave, so that the vibration energy is reflected and refracted multiple times, ultimately leading to faster energy attenuation and reducing the vibration intensity transmitted to other components; on the other hand, a 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 damping performance.

[0050] In an alternative embodiment, the electrical appliance further comprises:

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

[0052] Beneficial effect: The water pump is mounted on the fuselage through the mounting bracket, ensuring the stability and durability of the electrical appliance.

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

[0055] A second accommodating portion connected to the first end of the first accommodating portion and adapted to support the docking pipe in communication with the water pump.

[0056] Beneficial effect: The pumping assembly is arranged in the first accommodating portion of the bracket body, and the docking pipe is arranged in the second accommodating portion of the bracket body. The pumping assembly and the docking pipe in communication therewith can be firmly fixed through the mounting bracket at the same time, improving the connection reliability of the pumping device and the durability and stability of long-term use. Even when the pumping assembly is external to the liquid storage container, the durability and stability of the device can still be ensured.

[0057] In an alternative embodiment, the first accommodating portion comprises:

[0058] A first limiting wall;

[0059] A second limiting wall symmetrically arranged with the first limiting wall; the first limiting wall and / or the second limiting wall is / are provided with a clamping portion at the second end away from the first end of the first accommodating portion.

[0060] Beneficial effects: the pumping assembly can be limited in the specific installation space (the first accommodating part) by the symmetrically arranged first limiting wall and the second limiting wall, ensuring installation reliability; the clamping part is arranged, further improving connection reliability.

[0061] In an alternative embodiment, the clamping part comprises:

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

[0063] Beneficial effects: the clamping part comprises a plurality of clamping ribs, which can increase the friction coefficient between the pumping assembly and the mounting bracket, improving connection reliability.

[0064] In an alternative embodiment, the second accommodating part comprises:

[0065] A support part is arranged at one end of the second accommodating part close to the first accommodating part, and a concave support groove is formed on the support part.

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

[0067] Beneficial effects: the concave support groove can support the butt joint pipeline, improving the connection reliability of the butt joint pipeline and the pumping assembly; the limiting ring can limit and guide one end of the butt joint pipeline away from the first accommodating part, realizing reliable connection between the butt joint pipeline and the liquid storage container.

[0105] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0106] In the description of the utility model, it needs to be explained that, unless otherwise specified, the meaning of "multiple" is two or more than two; The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0107] In the description of the utility model, it also needs to be explained that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; It can be mechanical connection, or electrical connection; It can be directly connected, or indirectly connected through an intermediate medium. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0108] In the related art, the water pump of the cold fan is usually installed on the water tank, which causes great inconvenience to the user when taking the water tank, and is not convenient to maintain, affects the water quality, and also affects the heat dissipation. If the water pump is externally connected, the connection place is easy to leak: the water pump will vibrate when running, and the water in the water tank will have a certain impact and friction on the sealing place. After long-term use, the single sealing element will gradually age, the elasticity will decrease, and the sealing performance will decrease. At the same time, the relative movement between the water pump shaft and the sealing element will also cause the sealing element to wear and tear, resulting in gaps, so that water can easily leak out, not only causing waste of water resources, but also possibly damaging other parts of the cold fan, even causing electrical failure, and affecting the user's experience.

[0109] In addition, the external water pump will vibrate when running, and if it is not installed firmly, the vibration will be transmitted to the surrounding environment, producing noise and affecting the user experience, and at the same time, it may also cause the fixed parts of the water pump to loosen, further affecting its stability. The connection between the water pump and the pipeline usually adopts rigid connection, which further increases the transmission of vibration and noise, not only affecting the user experience, but also possibly damaging the equipment. Although some existing technologies try to use soft materials to reduce vibration, the effect is not significant, and the durability and stability of long-term use need to be improved. In view of this, the utility model is proposed.

[0110] The embodiments of the utility model will be described below in combination with Figures 1 to 12 , the description of the embodiments of the utility model.

[0114] a first sealing member 3 installed on the inner ring of the second valve body 21;

[0115] a second sealing member 4 installed 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 docking position of the first docking valve 1 and the second docking valve 2, forming double sealing, thereby improving the docking reliability of the first docking valve 1 and the second docking valve 2; when the sealing structure of the utility model is applied to the docking position of a liquid storage container and a pipeline, between liquid storage containers or between a liquid storage container and a pumping device, the occurrence of water leakage at the docking position can be avoided, and the reliability of fluid devices and electrical equipment can be improved. 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, which facilitates the formation of a first sealing barrier between the first valve body 11, the second valve body 21 and the first sealing member 3, and the formation of a second sealing barrier between the first valve body 11, the second valve body 21 and the second sealing member 4, and the structure is simple and the reliability is high.

[0118] When the two butt joints are connected, the first sealing member 3 is first contacted with the first butt joint valve 1 during the butt joint process, and a first closed cavity 10 as a first sealing barrier is formed between the first valve body 11, the second valve body 21 and the first sealing member 3, so that water leakage is prevented before the valve core is opened; and when the two butt joints are connected, the first valve body 11, the second valve body 21 and the second sealing member 4 form a second closed cavity 20 as a second sealing barrier, and the sealing effect is further enhanced under the double sealing action of the first sealing member 3 and the second sealing member 4, so that water leakage is prevented after the first butt joint valve 1 is connected with the second butt joint valve 2. Therefore, when the sealing structure is applied to the butt joint between the liquid storage container and the pipeline, the liquid storage container or the liquid storage container and the pumping device, the water leakage at the butt joint can be avoided, and the reliability of the electrical equipment is improved.

[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 the axial extension of 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 with the second valve body 21 to avoid being pulled out during the installation and fitting process; the sealing portion 42 formed by the extension of the mounting portion 41 can be sealed and fitted with the first butt joint valve 1 in the sealing ring groove, thereby forming the second closed cavity 20 and improving the sealing reliability.

[0127] According to the embodiments of the utility model, on the other hand, a fluid device is also provided, which comprises:

[0131] Since the fluid device comprises the sealing structure of the utility model, the same technical effects as the sealing structure are achieved, which will not be repeated here.

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

[0133] The liquid storage container and the pumping device are connected through the connecting pipeline 200 and double-sealed through the two connecting valves, so as to avoid water leakage at the connecting position of the liquid storage container and the pumping device, improve the sealing effect, and improve the user experience.

[0135] Since the electric appliance comprises the fluid device of the utility model, the same technical effects as the fluid device are achieved, which will not be repeated here.

[0136] In some embodiments, the electric appliance is a cooling fan, which comprises:

[0137] A machine body;

[0138] A water tank;

[0139] A water pump installed on the machine body; the water pump and the water tank are connected through the connecting pipeline 200.

[0140] The water pump of the cooling fan is installed on the machine body, and compared with the installation mode of the water tank, the water tank is more convenient to take and disassemble, but water leakage may occur when the water tank is taken, and the utility model sets two connecting valves at the connection position of the water tank and the connecting pipeline 200, realizes double sealing through the two sealing members, avoids water leakage of the water tank before the connection through the first closed cavity 10, and improves the sealing reliability of the water flow channel after the connection through the two seals of the first closed cavity 10 and the second closed cavity 20.

[0141] In some embodiments, the connecting pipeline 200 comprises a flexible pipeline.

[0142] The flexible pipeline is used as the connecting pipeline 200, which greatly reduces the vibration and noise compared with the rigid pipeline, improves the user experience, and prolongs the service life of the equipment.

[0143] It should be noted that the entire docking pipe 200 can be made of flexible material, or at least the part connected to the vibration source can be made of flexible pipe.

[0144] In some embodiments, the first end of the docking pipe 200 connected to the water pump is provided with a damping structure adapted to buffer the vibration energy absorbed by the water pump, so as to avoid the transmission of vibration energy along the docking pipe 200.

[0145] The damping structure is provided at the first end of the docking pipe 200 close to the water pump, which buffers the vibration energy absorbed and avoids the transmission of vibration energy 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, as shown in Figure 5 and Figure 6 The damping structure comprises:

[0147] The damping cavity 500 is arranged on the outer circumferential side of the docking pipe 200.

[0148] The arrangement of the cavity structure plays a role in consuming and absorbing vibration and noise. The air or other filling medium inside the cavity structure has friction and viscous effect with the structure wall surface, which can dissipate vibration energy, equivalent to increasing the damping of the structure; when subjected to vibration excitation, the cavity structure can disperse vibration energy to a larger area; due to the existence of the cavity, the stress distribution of the structure is more uniform, and local stress concentration leading to strong vibration can also be avoided; a 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 phenomena will occur in the cavity, and the incident sound waves and the reflected sound waves will interfere with each other and cancel out, thereby reducing the propagation and radiation of sound, thereby reducing noise. Moreover, the damping cavity 500 has a simple structure.

[0153] The first end of the adapter pipe 200 includes an inner pipe 201 and an outer pipe 202, and a groove as a damping cavity 500 is formed between the inner pipe 201 and the outer pipe 202. The adapter pipe 200 is connected to the vibration source through the inner pipe 201, and the groove is formed on the periphery of the connection to 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 limit of the width of the groove and the depth of the groove is not specifically limited here. In actual application, the width of the groove can be designed according to the diameter and length of the adapter pipe 200, and the depth of the groove can be reasonably selected according to the arrangement space size of the adapter pipe 200 and the vibration source. In addition, the material properties of the adapter pipe 200 should also be considered.
