Probe structure of multi-contact water sensor

Abstract

The invention discloses a probe structure of a multi-contact water sensor. The probe structure comprises a shell with a sealed head. At least two rows of small holes are vertically arranged in the surface of the shell; a probing sheet is mounted on each small hole; the probing sheets are mounted on the small holes of the shell in a reverse sealed bearing manner; the probing sheet and the shell can be insulated and sealed by using an insulating material; at least two probing conductors are packaged inside the shell; the outer part of each probing conductor is subjected to insulating treatment and is mounted corresponding to one row of small holes; and each probing conductor and the inner surface of the probing sheet near the probing conductor are in contact and get conducted. The probe structure of the multi-contact water sensor provided by the invention can be used for probing a plurality of water levels through one probe, and can select liquid difference of a plurality of different water levels according to demands; and a user can finely adjust the probing sheets at the upper parts of the different small holes, so that the using range is wider, and the length limitation of the probing probe can be avoided.

Description

technical field [0001] The invention relates to a water sensor probe structure, which belongs to the field of sensor elements and is specifically applied to detecting the water level of automobile water tanks and machine tool coolants. Background technique [0002] The probe structure of the liquid level sensor in the prior art is just a solid metal probe structure. Usually, a probe can only detect one liquid level data. If multiple liquid level data needs to be detected, multiple sensors must be used for detection. However, for a product with a certain structure such as an automobile water tank, it is obviously unrealistic to add additional openings to install sensors. The advanced sensor probe will provide a good choice for the transformation and improvement of the car. [0003] The existing probe structure generally can only detect a specific water level fixedly, and the standard for detecting the water level cannot be adjusted as required. [0004] In the prior art, th...
