[0002] A washing machine is a cleaning appliance that uses electric energy to generate mechanical action to wash clothes. According to its rated washing capacity, it is divided into two categories: household and collective use. A household washing machine mainly consists of a box body, a washing and dehydration barrel (some washing and dehydration barrels are separated), a transmission and control system, etc. Some are also equipped with a heating device. A washing machine generally refers to using water as the main cleaning liquid, different from using a special cleaning solution and dry cleaning usually carried out by a professional. A washing machine water level sensor is a sensor that does not reset, equivalent to a pressure switch.

[0003] The washing machine water level sensor is an important component for detecting the water level in the washing machine. The design and performance of its housing have a direct impact on the reliability and lifespan of the sensor. The existing housing of the washing machine water level sensor is usually made of plastic material. The plastic housing is not only easy to crack and damage, but also does not have the effect of electromagnetic shielding, which is likely to affect the lifespan of the induction components inside the housing and needs to be improved. Content of the Utility Model

[0025] The elastic component 2 includes an upper sleeve rod 21 and a lower sleeve rod 23 fixed to the outer wall of the outer waterproof layer 31. An adjusting spring 24 and a limiting rod 25 are fixedly connected inside the lower sleeve rod 23. The upper sleeve rod 21 and the lower sleeve rod 23 have the same structure. This structure can provide a certain space for "thermal expansion and contraction" when the outer casing 4 gets hot by setting the upper sleeve rod 21, the lower sleeve rod 23 and the telescopic rod 22, thereby improving the service life of the outer casing 4. At the same time, the elastic component 2 can also play the role of a reinforcing rib for the outer casing 4.

When the outer casing 4 deforms under high temperature conditions, the first anti-cracking layer 34 and the second anti-cracking layer 37 can play a certain role in anti-cracking. When the outer casing 4 is deformed by heat, the telescopic rod 22 synchronously expands and contracts between the upper sleeve rod 21 and the lower sleeve rod 23, thereby ensuring the service life of the outer casing 4.
