Problems solved by technology

[0004] However, the design of existing sensors is not without flaws, for example, in order to achieve their qualified indicators, the mechanical structure of existing sensors makes their size relatively large
Due to the trend of miniaturization of the volume of household appliances, this kind of pressure sensor is inconvenient to be installed in the limited space of household appliances
In addition, the arrangement of components inside the existing sensor is not suitable for reducing the size of the sensor

Abstract

The present invention discloses a pressure sensor. The sensor comprises: a housing comprising an upper housing and a lower housing, wherein a cavity is formed between the upper housing and the lower housing through the arrangement of the upper housing and the lower housing; a vibrating diaphragm arranged between the upper housing and the lower housing and configured to divide the cavity into an upper cavity and a lower cavity; a magnetic core moving with the motion of the vibrating diaphragm, wherein the vibrating diaphragm comprises a support body and thin skin arranged around the support body, the thin skin is extended from the edge of the support body, and the magnetic core is supported by the support body. The pressure sensor is small in volume and convenient to mount and dismount.

Description

technical field [0001] The present application relates to a sensor, in particular a pressure sensor for detecting operating parameters of household appliances. Background technique [0002] In some household appliances, such as washing machines, some operating parameters should be sensed in use to ensure the correct operation of the household appliance, such as sensing the uniformity of distribution of the clothes to be washed in the washing machine basket, and the pressure of the water supply and / or water level, etc. [0003] Pressure sensors are used in the prior art for sensing water pressure and / or water level. Pressure sensors generally include a rigid housing that houses a deformable membrane that is sensitive to air pressure; a pressure sensor also includes a magnetic core made of ferromagnetic material and operatively engaged with the membrane in response to movement due to deformation of the membrane; the coil is fixed to the housing, causing the coil to form a va...
