[0168] In some embodiments, the electric appliance is a cooling fan, the pumping assembly 300 includes a water pump, and the liquid storage container includes a water tank, and the water pump and the water tank are connected in communication through the docking pipeline 200.

[0169] Since the cooling fan adopts the pipeline connection structure 601 of the present application, the water pump and the docking pipeline 200 are reliably assembled through the mounting bracket 600, the connection reliability between the water pump and the docking pipeline 200 and the water tank is high, the durability and reliability of the cooling fan are improved, and the user's satisfaction is improved.

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

[0171] Compared with the use of a rigid pipeline, the use of a flexible pipeline as the docking pipeline 200 greatly reduces vibration and noise, improves user experience, and at the same time can prolong the service life of the equipment.

[0172] It should be noted that the docking pipeline 200 can be made of flexible material as a whole, or at least the part connected with the vibration source can be made of a flexible pipeline.

[0173] In some embodiments, the docking pipeline 200 is provided with a damping structure at the first end connected with the water pump, and the damping structure is suitable for buffering and absorbing the vibration energy of the water pump to avoid the transmission of vibration energy along the docking pipeline 200.

[0174] The damping structure is arranged at the first end of the connecting pipeline 200 close to the water pump, and the damping structure buffers and absorbs vibration energy, so that the vibration energy is not transmitted to the second end of the connecting pipeline 200 along the connecting pipeline 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 the satisfaction of the user.

[0175] In some embodiments, as shown in Figure 9 The damping structure includes:

[0176] The damping cavity 500 is arranged on the outer circumferential side of the connecting pipeline 200.

[0177] 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 effects 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; 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 occur in the cavity, and 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, thereby reducing noise. Moreover, the damping cavity 500 has a simple structure.

[0178] In some embodiments, the first end of the connecting pipeline 200 includes:

[0179] The inner tube 201 is adapted to be connected to the vibration source;

[0180] The outer tube 202 is arranged at the outer circumferential side of the inner tube 201 at intervals;

[0181] The groove is formed between the inner tube 201 and the outer tube 202, and constitutes the damping cavity 500.

[0182] The first end of the connecting pipeline 200 includes the inner tube 201 and the outer tube 202, and the groove as the damping cavity 500 is formed between the inner tube 201 and the outer tube 202. The connecting pipeline 200 is connected to the vibration source through the inner tube 201, and 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 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 connecting pipeline 200, the depth of the groove can be reasonably selected according to the arrangement space size of the connecting pipeline 200 and the vibration source, and in addition, the material properties of the connecting pipeline 200 should also be considered.

[0184] In some embodiments, the docking pipe 200 further comprises:

[0185] The partitioning ribs 203 are arranged between the inner pipe 201 and the outer pipe 202, and divide the damping cavity 500 into a plurality of cavities 501.

[0186] By dividing the damping cavity 500 into a plurality of cavities 501, the damping effect is improved. Dividing the damping cavity 500 into a plurality of small cavities 501 can increase the damping resistance on the one hand: the presence of a plurality of partitioning ribs 203 increases the resistance, thereby improving the energy consumption efficiency, which helps to more effectively absorb and convert vibration energy; 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, ultimately leading to faster energy attenuation, reducing the vibration intensity transmitted to other components; on the other hand, a reasonable layout of the partitioning 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 damping performance.

[0187] It should be noted that, in some embodiments, as shown in Figure 11 The partitioning ribs 203 can be a plurality of ribs arranged between the inner pipe 201 and the outer pipe 202 and arranged axially along the damping cavity 500, and the plurality of ribs divide the damping cavity 500 into a plurality of cavities 501 extending axially along the docking pipe 200. In other embodiments, the partitioning ribs 203 can also be honeycomb walls that divide the damping cavity 500 into honeycomb-shaped cavities.

[0188] As shown in Figures 1-10 The utility model discloses a cold fan, adopts the mode that water pump is external to water tank, and water pump is installed on the body of cold fan instead of traditional water tank, which is convenient for user to take water tank, and water pump is connected with second docking valve 2 through docking pipe 200 and installed at the predetermined position on the body of cold fan, to ensure that it is stable and has good sealing performance. First docking valve 1 is installed on the water tank, to ensure that it is stable and has good sealing performance, and first docking valve 1 and second docking valve 2 all include valve body, valve core and spring. First sealing piece 3 (first sealing ring 31) and second sealing piece 4 (second sealing ring) are assembled at second docking valve 2.

[0189] When the user installs the water tank on the machine, 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 element 3 first contacts the first docking valve 1 during assembly, forming a first closed cavity 10 to ensure that no water leaks before the valve core assembly is lifted open. As the water tank is further installed in place, the valve core assemblies are lifted open and the waterway is opened. At the same time, the second sealing element 4 forms a second closed cavity 20 with the first docking valve 1 to ensure the sealing of the entire connection 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 the problem of water leakage during assembly, and simplifies the user's operation steps.

[0190] The water pump of the cold air fan is fixed on the machine by the mounting bracket 600, and a sponge pad is arranged 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, and the water pump is indirectly contacted by a silica gel pipe and a sponge to be fixed on the machine, so that the damping performance is improved. At the end of the water pump away from the docking pipe 200, a sponge material with sound absorption and damping function is used for close wrapping. The mounting bracket 600 should be made of rust-proof and high-strength material to ensure the stability during long-term use. The docking pipe 200 is made of silica gel pipe, and high-quality silica gel material is selected to make the pipe, so that it has good elasticity and durability. The end of the silica gel pipe close to the water pump is designed as a hollow groove to increase the elasticity and reduce the vibration transmission. The silica gel pipe is connected between the water pump and the second docking valve 2, so that the connection is tight and leakage-free. Then, the water pump is fixed on the machine by the mounting bracket 600, and it is confirmed whether the parts are installed in place to ensure that the system operates normally and the damping and noise reduction effect is significant.

[0191] The utility model is suitable for various cold air fan products, especially in the scene that needs to frequently replace or clean the water tank. Through the external water pump and the double-sealing design, the utility model can significantly improve the market competitiveness of the cold air fan, and bring more convenient and reliable use experience to the user.

[0192] Although the embodiments of the utility model are described in combination with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the utility model, and such modifications and variations all fall within the range defined by the present application.
