They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] In related technologies, to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency, and to inhibit the growth of anaerobic bacteria in the water, preventing water deterioration from threatening the fish's living environment, aerators are commonly used to oxygenate fishponds. Impeller aerators are a common type of fishpond aeration equipment. Impeller aerators generally use an electric motor as the power unit. However, existing impeller aerators do not effectively solve the problem of heat dissipation during motor operation. The motor generates a large amount of heat during operation, causing it to overheat, especially in high-temperature environments during summer. If this high-temperature situation is not addressed promptly, it will result in a heavy load on the motor, leading to a shorter motor lifespan.

[0033] Therefore, this utility model provides an impeller-type aerator that can dissipate heat from the motor assembly during operation, which helps to improve the service life of the motor assembly.

[0034] Reference Figures 1 to 5 In some embodiments of this utility model, the impeller aerator includes a motor assembly and an impeller assembly. The motor assembly includes a motor and a reducer, with the reducer connected to the output end of the motor and the impeller assembly connected to the output end of the reducer. The impeller assembly includes a base 1 and multiple blades 2. The base 1 is connected to the output end of the reducer. The motor assembly can drive the base 1 to rotate. The multiple blades 2 are sequentially connected to the outer wall of the base 1 along its circumference. Each blade 2 is provided with a blade body 21, which is inclined from bottom to top in the direction of rotation towards the base 1. Therefore, when the blades 2 rotate with the base 1, they can lift the water below, allowing the water to fully contact the air and thus increasing the oxygen content in the water.

[0035] The blade 2 is also provided with a water guiding part, which is located at the upper end of the blade body 21. The water guiding part can guide at least part of the water flowing through the blade body 21 to the outer wall of the motor assembly.

[0036] The impeller aerator of this utility model has a water guide part on the blade 2, which is located at the upper end of the blade body 21. When the motor assembly drives the base 1 to rotate, the base 1 can drive the blade 2 to rotate. At this time, the blade body 21 can lift the water below upward. When the water flows through the water guide part, part of the water flow can be guided to the outer wall of the motor assembly, thereby dissipating heat from the motor assembly, reducing the operating temperature of the motor assembly, and improving the service life of the motor assembly.

[0037] Reference Figure 4It should be noted that in some embodiments of this utility model, the water guiding part is provided with a water guiding plate 22. The water guiding plate 22 extends upward along the upper end of the plate body 21 and is inclined in the direction away from the rotation of the base 1. When the blade 2 rotates with the base 1, the water flows from bottom to top along the plate body 21. When the water flows through the water guiding plate 22, since the water guiding plate 22 is inclined in the direction away from the rotation of the base 1, the water can splash out more towards the base 1 under the guidance of the water guiding plate 22.

[0038] It is understood that in some embodiments of this utility model, the water guide part is also provided with a V-shaped water guide plate 23. The water guide plate 23 is disposed at the upper end of the plate body 21 and connected to the water guide plate 22 to form a water outlet 25 with a gradually decreasing opening. When the water flows through the water outlet 25 with a gradually decreasing opening, the speed of the water flow can be increased, so that the water flow can splash higher, thereby dissipating heat to more parts of the motor assembly.

[0039] Specifically, in some embodiments of this utility model, the water guide plate 23 includes two plates 24 spliced ​​together, wherein the plate 24 closer to the base 1 is inclined towards the base 1 from bottom to top, so that when the water flows upward and splashes, more water can splash out towards the motor assembly on the base 1, thereby further improving the heat dissipation performance of the motor assembly.

[0040] It is understood that in some embodiments of this utility model, multiple water guide plates 23 are provided, and the multiple water guide plates 23 are spaced apart along the width direction of the upper end of the plate body 21, so as to guide more water flow toward the motor assembly and splash out, thereby further improving the heat dissipation capacity of the motor assembly.

[0041] Reference Figure 3 It is understood that in some embodiments of the present invention, the base 1 includes a motor mounting base 11 and a plurality of blade mounting bases 12. The motor assembly is mounted on the motor mounting base 11, and the plurality of blade mounting bases 12 are sequentially connected to the outer wall of the motor mounting base 11 along the circumference of the motor mounting base 11. The blades 2 can be detachably connected to the blade mounting bases 12.

[0042] Specifically, the motor mounting base 11 has an upwardly protruding boss 13 in the middle. The boss 13 is provided with a connecting hole 14 for connecting the motor assembly. During installation, the motor assembly is installed on the boss 13 by fasteners passing through the connecting hole 14. The upper end face of the boss 13 is higher than the bottom position of the blade mounting base 12. When the blade 2 is installed on the blade mounting base 12, the center of gravity of the blade 2 and the blade mounting base 12 can be basically level with the upper end face of the boss 13, which helps to improve the stability of the blade 2's rotation.

[0043] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments of this utility model, the blade mounting base 12 is provided with a locking hole 15, and the blade 2 is provided with a locking block 28 that is adapted to the locking hole 15. When installing the blade 2, the locking block 28 is inserted into the locking hole 15 to achieve pre-positioning, and then the blade 2 is fixed on the blade mounting base 12 by fasteners, making the installation more convenient.

[0044] Reference Figure 4 It is understandable that, in order to increase the contact area between water and air, in some embodiments of this utility model, the sheet 21 is provided with a plurality of water-lifting holes 26. The plurality of water-lifting holes 26 are arranged at intervals from bottom to top along the sheet 21. When the water flows upward along the sheet 21, part of the water flows out through the water-lifting holes 26, thereby forming more water droplets, which is beneficial to increasing the contact area between water and air, thereby increasing the oxygen content of the water.

[0045] It is understood that in some embodiments of this utility model, the blade 2 is also provided with a baffle plate 27. The baffle plate 27 is connected to the side of the blade 21 away from the base 1. The baffle plate 27 can prevent water from falling off the side of the blade 21 when it flows upward along the blade 21, so that more water can flow upward.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
