Abstract

The invention discloses an external additive feeding device. A filtering structure is detachably arranged on a water inlet pipeline, connected with an external water source, of the water inlet end of the external additive feeding device. The filtering structure can effectively filter out impurities such as scale in water, so that the smoothness and cleanliness of water flow entering the additive feeding device are guaranteed, and then the cleaning effect of clothes is effectively guaranteed. The filtering structure is detachably arranged, so that the filtering structure can be conveniently replaced or cleaned at regular intervals, the phenomenon that the filtering effect of the filtering structure is affected due to accumulation of a large amount of impurities after the external additive device is used for a period of time is prevented, the filtering efficiency of the filtering structure is better guaranteed, and the practicability and durability of the external additive device are enhanced.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an external additive injection device. Background technique [0002] Many existing washing machines have external additive injection devices, which are generally installed on the pipeline between the tap water connector and the water inlet valve of the washing machine. The additive injection devices include injection pumps and various types of additives stored inside In the additive liquid storage box, the water flows into the external additive injection device, and the additive in the liquid storage box is sucked out by the injection pump and injected into the pipeline, and flows into the washing machine together with the water. However, since the water contains various impurities, after a period of use, the pipeline of the external additive injection device is easily blocked or polluted, resulting in slow water intake or impurities entering the washing ...
