Filtering device for automobile water tank

Abstract

The invention discloses a filtering device for an automobile water tank, and belongs to the technical field of automobile parts. The filtering device comprises a shell and an end cover which are pressed into a whole through external force. A filtering part enabling the water outlet pipe and the water inlet pipe to be communicated is arranged in the cavity in the end cover. Springs in a compressed state are arranged at the bottom of the filtering part and the top of the water outlet pipe. A gap is formed between the bottom surface of the filtering part and the upper surface of the water outlet pipe by the springs. Cooling water to be filtered enters the filtering part through the water inlet pipe, is filtered outwards along the radial direction of the filtering part, enters the water outlet pipe through the gap between the bottom surface of the filtering part and the upper surface of the water outlet pipe, and flows out of the filtering device. The springs in the compressed state are mounted at the bottom of the inner side of the shell, so that the filter screen and other filter components can be tightly pressed and prevented from loosening under the action of water pressure or bumping vibration, and the service life of the filtering device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a filtering device for an auto water tank. Background technique [0002] The cooling water tank of the car is an important device for cooling the heat generated during the running of the car. The cooling device generally includes components such as a shield, a filter screen, a magnet, and an overflow valve. The filter is generally installed at the water inlet end of the car heater tank. The engine can produce solid impurities due to its own casting or during operation. The filter intercepts these solid impurities through its own filter screen and other filter components. However, during the use of the car filter device, the following problems were found: [0003] 1. During the long-term use of the car, due to water pressure, bumps and vibrations, etc., the filter screen and other components built in the outer shell will become loose, thereby reducing the filter...
