Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of solar water heater water-temperature water-level sensor.
Background technology
The solar water heater controller that is used to show and controls solar water container water level and water level is generally accepted by the user at present, and its performance quality directly has influence on user's life.Played important role therein as the sensor that detects the water tank water-temperature water-level.The sensor long-term work is in high-temperature water tank, and its serviceable life is all shorter always for various reasons.The sealing problem of high temperature, incrustation scale and sensor self is the difficult problem that sensor is difficult to overcome always.And the water quality of China various places differs, mountain portion area water quality is pure especially, this has also reduced the accuracy of detection of sensor unavoidably, and some sensor even detect less than water level in those zones has had a strong impact on development and the popularization of solar water heater controller in above-mentioned area.
Summary of the invention
The purpose of this utility model is intended to invent and a kind ofly effectively prevents incrustation scale, and accuracy of detection higher solar energy water heater temperature level sensor.
To achieve these goals, the technical solution of the utility model is: a kind of novel water-temperature water-level sensor, the inner core of sensor is by little stainless-steel tube I (13), water temperature detecting element (11), water level detecting element (1,2,3,4) and water-temperature water-level common port (5) constitute, water level detecting element (1,2,3,4) and water temperature detecting element (11) be welded in stainless steel compressing tablet (6 respectively, 7,8,9,10) on, and be connected to each other to water-temperature water-level common port (5) stainless steel compressing tablet (6 simultaneously by stainless steel wire (12), 7,8,9,10) be attached on the little stainless-steel tube I (13) by stainless steel wire (12).
Utilize insulation silica gel (14,16,18,20,22) and electric silica gel (15,17,19,21) to carry out separation seal respectively in the outside of the sensor inner core.The big stainless-steel tube II (25) that also has a groove with holes in the silica gel outside is provided with support member (23) and (24) on insulation silica gel (16) and (20), big stainless-steel tube II (25) is not directly contacted with electric silica gel (15,17,19,21).
Water-temperature water-level sensor of the present utility model is provided at an outer portion with the stainless-steel tube II that has hole slot, and stainless-steel tube II and inner silica gel utilize support member to be spaced from each other.When water-temperature water-level detected, water storage entered stainless-steel tube II inside by hole slot, made electric silica gel and outside stainless-steel tube II conducting, carried out water level detecting thus.Above-mentioned design has increased the conductive area of sensor, is playing positive effect aspect the opposing incrustation scale.The water-temperature water-level detecting element of sensor of the present utility model is welded in respectively on the stainless steel compressing tablet, utilize stainless steel wire to be interconnected to the water-temperature water-level common port between each stainless steel compressing tablet, and invest on the inner stainless-steel tube I, form the sensor inner core, and utilize electric silica gel and insulation silica gel separation seal in the inner core outside.Above-mentioned design utilizes stainless steel wire as internal connection line, and the signal transmission is more reliable, and the detection sensitivity of sensor is higher, can adapt to purer water quality area and use, and helps the further popularization of solar water heater.
