Description

Technical Field

[0001] This utility model relates to the field of water pumps, and in particular to a water pump with heat dissipation function. Background Technology

[0002] A water pump is a mechanical device that transfers the mechanical energy of a prime mover or other external energy to a liquid, thereby increasing its energy. Water pumps are mainly used to transport various liquids.

[0003] Existing water pumps typically include a pump body, a rear cover, and a heat dissipation assembly. The rear cover is installed at the end of the pump body, and the heat dissipation assembly is placed on the rear cover, thereby allowing the heat dissipation assembly to cool the interior of the pump body.

[0004] Heat dissipation components typically include a built-in cooling fan and a heat sink. The heat sink is located at the end of the back cover, and the cooling fan is placed inside the back cover. The cooling fan and heat sink can dissipate heat from the inside of the water pump body. However, the heat sink on the water pump body is usually exposed to the outside. As a result, when the water pump is not in use, external dust and other contaminants can continuously enter the inside of the water pump body from inside the heat sink on the back cover. This causes dust to adhere to the cooling fan and other components, affecting the cooling efficiency of the cooling fan. Furthermore, it is not convenient to cover and protect the heat sink on the back cover when the water pump is not in use, which has certain limitations. Utility Model Content

[0024] 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.

[0025] This utility model provides, for example Figure 1-5 The water pump shown includes a water pump body 1, a rear cover 2 installed on the side of the water pump body 1, and a heat dissipation groove 3 opened on the side of the rear cover 2, which is conducive to heat dissipation of the interior of the water pump body 1.

[0026] Furthermore, the rear cover 2 is provided with a shielding mechanism 4 for sealing the interior of the heat dissipation slot 3. The shielding mechanism 4 includes a shielding cover 41, a positioning rod 44, and a positioning seat 413. The shielding cover 41 can be rotated to overlap with the side of the rear cover 2, thereby protecting the interior of the heat dissipation slot 3 on the rear cover 2 when the water pump body 1 is not in use, preventing external dust and other contaminants from continuously entering the interior of the water pump body 1 through the interior of the heat dissipation slot 3. The positioning rod 44 cooperates with the positioning seat 413 to facilitate the rotation of the shielding cover 41 to expose the interior of the heat dissipation slot 3. The cover 41 is fixed in place to limit the heat dissipation slot 3 for normal use and heat dissipation. The cover 41 is provided with a fixed shaft 42, which is beneficial for supporting the cover 41 and making it easy for the cover 41 to rotate in a circle around the fixed shaft 42 for storage or use. The cover 41 is rotatably set on the side of the rear cover 2 through the fixed shaft 42. The positioning rod 44 is slidably set on the cover 41, and the positioning seat 413 is located on the side of the cover 41. The positioning rod 44 and the positioning seat 413 are used to lock the rotation position of the cover 41.

[0027] Furthermore, the end of the fixed shaft 42 is fixedly connected to the rear cover 2, and the outer wall of the fixed shaft 42 is rotatably connected to the cover 41. The end of the fixed shaft 42 is slidably connected to the limit cap 43, which helps to limit the position of the cover 41 and facilitates the installation and removal of the cover 41. An operating plate is provided on the outside of the limit cap 43, which helps to pull the mounting rod 46. The outside of the limit cap 43 is provided with a first circular groove, and the inner cavity of the first circular groove is slidably connected to the mounting rod 46, which helps to control the position of the limit cap 41. The relative position of the fixed shaft 42 and the fixed shaft 42 is defined to facilitate the installation and removal of the limit cap 43. The fixed shaft 42 has an installation hole on its outside that mates with the mounting rod 46. The end of the mounting rod 46 is fixedly connected to the operating plate. The limit cap 43 has a second circular groove on its outside. An elastic rope 47 is fixedly connected to the inner wall of the second circular groove. The tension of the elastic rope 47 helps the operating plate to move the mounting rod 46 and then return it to its original position, which facilitates repeated operation of the mounting rod 46. One end of the elastic rope 47 is fixedly connected to the operating plate.

[0028] Specifically, the side of the cover 41 has a third circular groove that mates with the positioning rod 44. The positioning seat 413 is fixedly connected to the outside of the rear cover 2. The positioning rod 44 is slidably inserted into the inner cavity of the positioning seat 413. A fixing cylinder 45 is fixedly connected to the side of the cover 41, which facilitates horizontal guidance and support for the sliding of the positioning rod 44 and the pulling rod 48. A pulling rod 48 is slidably inserted into the side of the fixing cylinder 45, which facilitates pulling the positioning rod 44 to move and makes it easy to pull the positioning rod 44. The end of the pulling rod 48 is threadedly inserted into the positioning rod 44. A sliding plate 49 is fixedly connected to the outer wall of the positioning rod 44, which helps to limit the position of the positioning rod 44 and also helps to drive the second magnet 411 to move. A first magnet 410 is symmetrically fixedly connected to the side of the inner wall of the cylinder 45. The first magnet 410 and two of the second magnets 411 are used to limit the position of the sliding plate 49, so as to limit the positioning rod 44 hidden inside the cover 41. The two sides of the sliding plate 49 are fixedly connected to the second magnets 411, and the opposite magnetic poles of the two first magnets 410 and the second magnets 411 are opposite to each other. A magnet ring 412 is embedded in the inner cavity of the fixed cylinder 45, which is convenient to connect with the other two second magnets 411 to limit the connection position of the positioning rod 44 and the positioning seat 413, so as to limit the position of the positioning rod 44 and prevent the positioning rod 44 from sliding randomly. The other two second magnets 411 and the magnet ring 412 are opposite to each other.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
