Automobile windscreen washing pump

Abstract

The invention discloses an automobile windscreen washing pump which comprises an end shield (1). The end shield (1) is connected with the first end of an outer cover (3) through ultrasonic welding. The second end of the outer cover (3) is connected with a pump cover (6) through ultrasonic welding. A water inlet (9) and a water outlet (10) are formed in the two ends of the pump cover (6). A filterscreen (7) is arranged on the water inlet (9). A motor (2) is fixedly installed in the outer cover (3). One end of the motor (2) is provided with an electrode insertion sheet (8) extending in the endshield (1) to be connected with an automobile power source, a shaft seal (4) and an impeller (5) are installed on a motor shaft (12), extending into the pump cover (6), at the other end of the motor (2), and the shaft seal and the pump cover are sealed to form a pump chamber (11). The automobile windscreen washing pump has the beneficial effects of being simple in structure, few in installation procedure, low in cost, high in production efficiency, good in waterproof performance and the like and can be widely applied to automobile windscreen washing.

Description

technical field [0001] The invention relates to a water pump, in particular to an automobile windshield washing pump. Background technique [0002] The end cover and outer cover, outer cover and pump cover of automobile windshield washer pumps in the market mostly adopt bonding or fastening connection mode. [0003] The bonding method needs to consume bonding materials, and the bonding drying time generally takes 6 to 24 hours, and the bonding effect is affected by various factors such as bonding materials, time, temperature, humidity and the surrounding environment. This connection method takes a long time. Low efficiency and unstable bonding effect. [0004] When the fastening method is used, because there will be gaps during the fastening, some cars require a higher waterproof level of the washing pump to reach IP67 (entering 1m underwater, soaking for 30min; there is no water inside the washing pump), and the waterproof level requirements For high-end cars, if you want...

[0003] The bonding method needs to consume bonding materials, and the bonding drying time generally takes 6 to 24 hours, and the bonding effect is affected by various factors such as bonding materials, time, temperature, humidity and the surrounding environment. This connection method takes a long time. Low efficiency and unstable bonding effect

[0004] When the fastening method is used, because there will be gaps during the fastening, some cars require a higher waterproof level of the washing pump to reach IP67 (entering 1m underwater, soaking for 30min; there is no water inside the washing pump), and the waterproof level requirements For high-end cars, if you want to ensure that there is no water in the washing pump, you need to add a sealing ring at the fastening connection, which increases the cost and cumbersome process; and the fastening effect is greatly affected by manual operation skills, and cannot be accurately grasped
