 具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
根据图1-图10所示：
一种用于家用电器的倾斜传感器，包括固定支架1和倾斜传感器2，所述倾斜传感器2设于固定支架1顶部，所述固定支架1前端连接有压块3，所述倾斜传感器2包括磁珠组合21、磁簧管22和定点勾槽23，所述定点勾槽23开于倾斜传感器2面端，所述磁簧管22设于定点勾槽23后端，所述磁珠组合21设于磁簧管22后端。
所述固定支架1还包括线位固定柱11、斜面连片12和线绕定位柱13，所述斜面连片12设于线绕定位柱13后端，所述线绕定位柱13包括从上到下设置的对位连孔131和绕线支点132，所述线位固定柱11分别设于线绕定位柱13左右两端，包括分别开于面端的契合槽111。
因为所述压块3包括压位片一31、压位片二32和固位片33，所述压位片二32设于压位片一31底端，所述固位片33分别设于压位片二32左右两端，所述固位片33分别与契合槽111相配合，所述压位片二32包括开于内部压位连孔321，所述压位片二32通过压位连孔321和对位连孔131对孔与线绕定位柱13连接，所以当用户使用本发明时，通过对孔，使得压块3紧密的设于固定支架1面端。
因为所述磁簧管22底部分别连接有连接导线221，所述连接导线221依次设于线位固定柱11内和缠绕于绕线支点132内，且所述连接导线221分别由固位片33和压位片二32限位，所以当用户使用本发明时，所以当用户使用本发明时，通过连接导线221在依次通过线位固定柱11和缠绕于绕线支点132内，能保证了连接导线221于固定支架1内与磁簧管22的连接段不会出现线路位置四处抖动和跑偏的情况，从而影响本发明的正常使用。
因为所述磁簧管22底部还设有卡扣222，所述卡扣222包括卡扣契合勾2221和磁簧管承托臂2222，所述磁簧管承托臂2222由磁簧管22承托，所述卡扣契合勾2221与定点勾槽23相配合，所述倾斜传感器2由压位片一31限位，所以当用户使用本发明时，在磁簧管22设于倾斜传感器2后，然后向上推动卡扣222使得其与定点勾槽23相配合，从而能对磁簧管22的位置进行承托和限位，防止在使用时出现位置抖动跑偏的情况。
因为所述磁珠组合21包括从外到内设置的钢球211和磁铁212，所述磁簧管22由磁铁212导通，且所述磁珠组合21外侧还开有螺丝孔213，所述螺丝孔213内连接有丝帽，所以当用户使用本发明时，由磁簧管22和磁珠组合21组成的倾斜传感器2，作为斜度感应元件，当本发明与外部电器正立连接时(指磁珠组合21与外部电器平行状态)，磁簧管22这时接点受磁铁212磁场作用导通，当外部电器受到震动或其他一些不良移动时，这时外部电器就会反生倾斜，当斜度达到一定时，钢球211就会因为重力的原因驱动磁铁212会滑向斜面的底端，这时磁铁212与磁簧管22失去导通，实时的磁簧管接点断开。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
