Description

Technical Field

[0001] This utility model relates to the field of anti-bed mattress technology, and in particular to an anti-bed mattress with automatic identification and voltage control. Background Technology

[0002] Current mattresses all use a fixed input voltage power supply method, and the internal components are AC steering motors and AC inductor air pumps. They are low in cost and have a long lifespan. However, these motors or air pumps are designed for a specific voltage and cannot achieve a wide voltage operating mode. As a result, the voltage needs to be customized according to the mains power in the user's area. This can easily lead to damage due to mains voltage mismatch, resulting in unnecessary losses.

[0003] To achieve a wide voltage operating mode, a frequency converter circuit needs to be added, and the increased cost is unacceptable compared to similar products. If a DC motor or DC air pump is used, then the following problems arise:

[0004] a: If a DC brushed motor is used, the brushed motor has a very short lifespan (about 600 hours) due to the presence of brushes. However, mattresses are basically in a state of long-term operation, so the lifespan of this type of motor cannot meet the requirements.

[0005] b: DC brushless motor. This type of motor is inherently more expensive, but it also requires a separate drive circuit, so it cannot be used in similar products due to cost considerations. Utility Model Content
