[0002] Electric water pumps have high output efficiency and can achieve precise flow control. Therefore, they are widely used in household appliances, automobiles, and industrial equipment. For example, household appliances such as air conditioners, water-heated mattresses, and humidifiers are increasingly equipped with electric water pumps to achieve precise quantitative liquid circulation / discharge functions.
[0003] Drain pumps are an important application of electronic water pumps. They can drain liquids from structures such as water tanks and troughs to other places. For example, some types of air conditioners are equipped with drain pumps to help drain condensate.
[0004] An electric water pump contains a rotor assembly and an impeller to drive the flow of liquid media. When the rotor assembly and the impeller rotate, mechanical vibration occurs. In addition, when the liquid media flows in the pump chamber of the electric water pump, water flow pulsation occurs, which in turn causes the pump chamber of the electric water pump to vibrate. When the electric water pump is used as a drainage pump in an air conditioner, the above-mentioned vibration is transmitted through the housing of the electric water pump to the housing / mounting bracket of the air conditioner, causing the air conditioner to vibrate as well, affecting the air conditioner's quietness, operational stability and service life.
[0005] In conclusion, providing a reasonable and reliable vibration damping structure for electronic water pumps has become one of the urgent problems to be solved. Utility Model Content

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This embodiment provides a vibration damping structure for an electromechanical device, which is applied to the electromechanical device 10.
[0021] Specifically, the electromechanical device 10 is a device that will experience mechanical vibration after being powered on, such as an electric water pump, fan, turbine fan, axial flow fan, motor, and air pump.
[0022] Please see Figures 1-3 The electromechanical device 10 includes at least a mounting foot 101 with a mounting hole 104.
[0023] Specifically, the mounting foot 101 can be configured on the housing of the electromechanical device 10 (either integrally formed with the housing of the electromechanical device 10 or independently installed on the housing of the electromechanical device 10), or it can be configured on the mounting bracket of the electromechanical device 10 (again, either integrally formed with the mounting bracket of the electromechanical device 10 or independently installed on the mounting bracket of the electromechanical device 10).
[0024] The mounting hole 104 is a hole-like structure that is formed at the mounting foot 101 of the electromechanical device 10 and passes through the mounting foot 101.
[0025] The electromechanical device vibration damping structure of this embodiment includes a vibration damping component 20 and a fastener 30.
[0026] The damping component 20 is made of one of the following materials: rubber, silicone, or flexible plastic, which makes the entire damping component 20 elastic and its outer contour is roughly ring-shaped.
[0027] The fastener 30 is one of screw, bolt and rivet, and has an end 301 and a rod-shaped body. In this embodiment, the fastener 30 is a screw.
[0028] The vibration damping component 20 is embedded in the mounting hole 104 of the electromechanical device 10. After the fastener 30 passes through the vibration damping component 20, it is fixed at the fixing object 40. In this way, the mounting foot 101 of the electromechanical device 10 is fixed at the fixing object 40.
[0029] It should be noted that the aforementioned fixing object 40 specifically refers to the fixing object 40 at the equipment on which the electromechanical device 10 is applied, such as the equipment's casing, internal support, or frame.
[0030] One end face of the damping member 20 abuts against the fixed object 40 so that the mounting foot 101 of the electromechanical device 10 makes flexible contact with the fixed object 40; the other end face of the damping member 20 abuts against the end 301 of the fastener 30 so that the mounting foot 101 of the electromechanical device 10 makes flexible contact with the fastener 30.
[0031] This configuration provides a reliable mounting structure for the electromechanical device 10, while allowing the mounting feet 101 of the electromechanical device 10 to flexibly contact both the fixed object 40 and the fastener 30. After the electromechanical device 10 is powered on, the mechanical vibrations generated are isolated by the vibration damping component 20, preventing them from being directly transmitted to either the fixed object 40 or the fastener 30. Without altering the original mounting structure of the electromechanical device 10, this improves the vibration / resonance phenomenon of the electromechanical device 10 and the equipment using it, thereby enhancing the quietness, operational stability, and service life of the electromechanical device 10 and the equipment using it. Furthermore, it effectively prevents the fastener 30 from gradually loosening under vibration, improving the reliability of the electromechanical device 10 during installation.
[0032] Please refer to the following: Figure 3 Specifically, the two end faces of the damping member 20 are respectively configured as a fixing contact portion 201 and a fastener contact portion 203. In fact, the fixing contact portion 201 and the fastener contact portion 203 are annular rib-shaped structural features integrally formed on the two end faces of the damping member 20. The fixing contact portion 201 of the damping member 20 protrudes outward beyond the mounting hole 104 of the electromechanical device 10 and abuts against the fixing object 40. The fastener contact portion 203 of the damping member 20 protrudes outward beyond the mounting hole 104 of the electromechanical device 10 and abuts against the end 301 of the fastener 30.
[0033] Furthermore, the sidewall of the damping member 20 is concave to form an annular groove 202. In fact, the annular groove 202 is an annular groove structure integrally formed in the middle of the damping member 20. The inner wall of the mounting hole 104 of the electromechanical device 10 protrudes outward to form a retaining rib 105. In fact, the retaining rib 105 is an annular rib structure integrally formed in the mounting hole 104. When the damping member 20 is embedded in the mounting hole 104 of the electromechanical device 10, the retaining rib 105 of the electromechanical device 10 is engaged in the annular groove 202 of the damping member 20. In this way, the damping member 20 and the mounting hole 104 of the electromechanical device 10 are integrated into one unit, reducing the operation steps of adding the damping member 20 during the installation of the electromechanical device 10.
[0034] Furthermore, the mounting foot 101 of the electromechanical device 10 includes: an extension 102 extending from the electromechanical device 10, and a planar contact portion 103 connected to the free end of the extension 102 and adapted to fit against the fixing object 40; in fact, the extension 102 and the planar contact portion 103 are configured as an integrally formed structure; by providing the extension 102, the planar contact portion 103 is moved away from the body of the electromechanical device 10, increasing the operating space of the electromechanical device 10 during installation; by providing the planar contact portion 103, the mounting foot 101 can fit against the fixing object 40, improving the reliability of the electromechanical device 10 during installation.
[0035] This embodiment also provides an electronic water pump, which includes the above-described electromechanical device vibration damping structure.
[0036] It is understood that in this embodiment, the electronic water pump is the electromechanical device 10. When the electronic water pump is used as an air conditioner drain pump, the fixing object 40 is the air conditioner's outer casing, top plate, internal support, or frame.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
