Description

Technical Field

[0001] The utility model relates to air pump technology, in particular to a waterproof air pump used for fishing. Background Art

[0002] When fishing, the fish need to be supplied with oxygen to keep them fresh. Usually, an air pump is used to supply oxygen. Because fishing is mostly done outdoors and is affected by the environment and climate, the probability of the air pump falling into the water or getting wet is very high. Therefore, fishing pumps used outdoors must have high waterproof requirements.

[0003] However, the air pump currently used is a leather cup air pump, which presses the leather cup through the principle of alternating magnetic field; the air cavity of the leather cup air pump on the market is usually set inside the shell of the electromagnetic device, causing the air cavity and other functional components inside the shell to be mixed in the same space. In order to ensure that the air flow enters the air cavity in the shell, the shell is provided with an air intake grille to keep the air cavity and the external space connected. Such a design destroys the overall sealing of the shell, and the air flow and water flow will pass through the air intake grille into the interior of the shell. In this way, when used outdoors, the electromagnetic device and circuit set inside the shell are at risk of being immersed in water.

[0004] In order to solve the above problems, it is necessary to develop an air pump with a shell that is sealed and waterproof, and an air inlet and outlet that are independent of the shell, so as to improve the waterproof function of the device. Utility Model Content
