Description

Technical Field

[0001] This invention belongs to the field of water pump technology and relates to a vortex pump. Background Technology

[0002] Most existing pumps rely on heat dissipation fins for conventional heat dissipation, but the effect is not very good. To improve the heat dissipation, they are usually equipped with an air-cooling structure, which mainly involves setting a fan at one end of the pump body and adding flow holes on the end cover to enhance airflow at the heat dissipation fins. However, in actual use, in order to reduce the entry of impurities into the fan end, a filter structure is usually set to filter impurities. However, the filter structure affects the fan's airflow guiding effect. At the same time, the airflow will overflow after flowing through part of the pump body shell, causing a difference in heat dissipation efficiency between the front and rear ends of the pump body. Therefore, even when equipped with a heat dissipation fin structure, the heat dissipation effect is still not good, thus failing to meet the usage requirements. Summary of the Invention

[0005] In the aforementioned vortex pump, the pump body has a second convex ring portion that protrudes radially outward and slides in cooperation with the first convex ring portion on its outer peripheral wall connected to the first convex ring portion.

[0006] In the aforementioned vortex pump, an inclined surface is provided on the rear end of the sliding cover, and a sealing ring is provided between the sliding cover and the protective cover, which is embedded in the sliding cover.

[0013] like Figure 1As shown, this vortex pump includes a pump body 2 with an electrical control box 1 and a fan body. The pump body 2 has an output shaft for mounting and rotating the fan body. The pump body 2 also has several heat dissipation fins connected to and spaced apart along its circumference, with heat dissipation channels between adjacent fins. The output shaft is a dual-shaft structure. The pump body 2 has a protective cover 3 connected to and protecting the fan body. The front end of the protective cover 3 has several air inlets for airflow, and the rear end of the protective cover 3 has several air outlets for airflow. The protective cover 3 has a sliding cover 4 that slides with it. The inner circumferential wall of the sliding cover 4 at its rear end has a radially outward protrusion that... The pump body 2 has a convex ring 5 that slides on its outer peripheral wall. Several plugs 6 connected to the convex ring 5 and used to seal the vent holes are provided on the inner wall of the convex ring 5 at the corresponding vent hole. A moving unit connected to the convex ring 5 and used to control the axial reciprocating movement of the sliding cover 4 is provided on the pump body 2.

A heat dissipation unit connected to the heat dissipation channel and also to the convex ring 5 is provided on the pump body 2 at the heat dissipation channel to ensure heat dissipation. A second convex ring 7, radially protruding and slidingly fitted with the convex ring 5, is provided on the outer peripheral wall of the pump body 2 connected to the convex ring 5. A [missing information - likely a design feature] is provided on the rear end of the sliding cover 4. On the inclined surface, a sealing ring is provided between the sliding cover 4 and the protective cover 3, embedded in the sliding cover 4 or the protective cover 3. A sealing ring can also be provided between the first convex ring 5 and the second convex ring 7. The number of such sealing rings can be multiple. The moving unit includes a push rod motor with an output rod. The push rod motor is mounted on and connected to the water pump body 2, and the push rod motor is controlled to open and close through the aforementioned electrical control box 1. The output rod in the push rod motor is connected to the sliding cover 4. The heat dissipation unit includes a hollow heat dissipation rod 8, and several heat dissipation holes are provided on both sides of the heat dissipation rod 8 at intervals along its length.
