Problems solved by technology

[0004] Since the rubber film is a flexible element, there is a gap in the movement of the magnetic core, which cannot ensure that the magnetic core moves upward in a straight line. At the same time, the water level spring has non-perpendicularity, and when the water level spring meets the washing water level requirements, the spring is in a free state at zero water level. The magnet will shake at the end when it reaches the washing water level, and it is impossible to achieve precise control of the water level

Embodiment Construction

[0086] Such as figure 1 and figure 2 and image 3 and Figure 4 As shown, the compact water level sensor includes a housing, a sealing film 3, a guide rod 4, an LC oscillating circuit mechanism, and a magnetic core 5. The interior of the housing is a cavity, and the sealing film 3 is connected to the housing and connects the housing Separated into two chambers adjacent up and down: the upper chamber and the lower chamber, the above-mentioned LC oscillation circuit mechanism is fixedly connected to the upper part of the housing, the lower end of the above-mentioned guide rod 4 is fixedly connected with the sealing film 3, and the upper end of the guide rod 4 The above-mentioned magnetic core 5 is fixedly connected to the guide rod 4. When the sealing film 3 acts on the pressure of the fluid medium, the guide rod 4 will move up and down with the sealing film 3. The above-mentioned magnetic core 5 will move up and down with the guide rod. 4. After synchronous movement, the na...

Abstract

The invention provides a compact water level sensor and belongs to the technical field of machines. The problem that in the prior art, the structure is not compact is solved. The compact water level sensor comprises a shell, a sealing film, a guide rod, an LC oscillation circuit mechanism and a magnetic core. The LC oscillation circuit mechanism comprises a connection cylinder, a coil, an electric pin and a capacitor, the connection cylinder is located on an upper shell and cylindrical, the coil is wound on the outer side of the connection cylinder, the inner end of the electric pin is located in the upper shell and connected with the capacitor, and the outer end of the electric pin extends out of the upper shell. The compact water level sensor is compact in structure.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a compact water level sensor. Background technique [0002] The prior art water level sensor for a washing machine comprises a shell, a rubber film, a coil, a magnetic core fixed outside the magnetic core seat, a spring seat fixed in the magnetic core seat, a water level spring and an adjusting bolt. [0003] There is an air duct interface on the shell, and the magnetic core seat connected to the rubber film moves with the rubber film, causing the magnetic core to produce pressure-related displacement, thereby changing the natural frequency of the coil and capacitor. The above frequency signal is passed through the washing machine. The computer chip turns into a control signal that controls the water valve. [0004] Since the rubber film is a flexible element, there is a gap in the movement of the magnetic core, which cannot ensure that the magnetic core moves upwards in a straig...
