The small and medium-sized parts of the full-automatic feeding mixer are easy to be damaged, so we must take care of them carefully when using them. What are the reasons for the failure of the horn of the full-automatic feeding mixer? After reading the following, we will understand how to take care of the horn:

1、电磁线圈端子接触不良：有些喇叭内部电磁线圈漆包线端子接头是铝金属铆钉压接连接的，非牢靠焊接连接，如果端头漆包线上的绝缘漆处理不净或铆钉压接不牢靠很容易产生虚接故障，导致喇叭工作不良。此种故障是喇叭质量原因，无法修，只能换上新的零件。

1. Poor contact of solenoid coil terminals: the terminal joints of solenoid coil enamelled wire inside some horns are crimped and connected by aluminum metal rivets, which are not firmly welded. If the insulating paint on the end enamelled wire is not treated cleanly or the rivets are not firmly crimped, it is easy to produce virtual connection fault, resulting in poor operation of the horn. This failure is due to the quality of the horn and cannot be repaired. Only new parts can be replaced.

2、密封不严易受潮：虽然小型全自动上料搅拌机喇叭内部是密闭的，但如果密封不严清洗全自动上料搅拌机时进入雾气或内部空间空气中有水蒸气，水蒸气很容易导致触点受潮无法正常工作。

2. Poor sealing and easy to be affected by moisture: Although the interior of the horn of the small full-automatic feeding mixer is sealed, if the sealing is not tight, when cleaning the full-automatic feeding mixer, it enters the fog or there is water vapor in the air of the internal space, which is easy to cause the contact to be affected by moisture and cannot work normally.

3、触点烧蚀：如果长时间按喇叭易造成喇叭触点烧蚀而产生阻抗，流过电磁线圈的电流减弱，小型全自动上料搅拌机电磁吸力下降无法吸引衔铁带动膜片正常振动，导致发音沙哑、甚不响。但不断按喇叭时，若瞬间强电流通过阻抗依然能正常工作，所以会时好时坏。

3. Contact ablation: if you press the horn for a long time, it is easy to cause the horn contact ablation and produce impedance, the current flowing through the electromagnetic coil is weakened, the electromagnetic suction of the small automatic feeding mixer is reduced, and the armature cannot be attracted to drive the diaphragm to vibrate normally, resulting in hoarse pronunciation or even no sound. However, when the horn is constantly sounded, if the instantaneous strong current passes through the impedance, it can still work normally, so it will be good and bad from time to time.

当我们了解了这些会使机器出现故障的原因后，我们在使用它时一定要保护好它的喇叭，避免以上的问题。小型全自动上料搅拌机在启动的时候偶尔按一下喇叭，仔细听喇叭发出来的响声。

When we understand the causes of these failures, we must protect its horn when using it to avoid the above problems. When the small automatic feeding mixer is started, occasionally press the horn and listen carefully to the sound made by the horn.
