Technical field
The utility model relates to a kind of water-temperature water-level sensor, and is specifically a kind of for detection of the water heater sensor of water-temperature water-level in solar water heater water tank particularly.
Background technology
Water-temperature water-level sensor is arranged in the water heater water tank of (comprising solar water heater), for detection of the water temperature in water tank and water level.The structure of existing water-temperature water-level sensor generally comprises water-temperature water-level sensing circuit, public electrode, water level induction section and electrically insulating silicone rubber pipeline section.Water level induction section generally comprises four sections, is respectively used to sensing 20%, 50%, 80% and 100% 4 water level, and arranges from outside to inside successively, and the outermost side of water-temperature water-level sensor is public electrode, and the water level induction section of 20% water level is positioned at the public electrode inboard.Distant due between the water level induction section of 80% and 100% water level of public electrode and medial extremity therefore in actual use procedure, tends to for the sensing of 80% and 100% water level the insufficient sensitivity that seems, affected the accuracy of water-temperature water-level sensor work.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of highly sensitive, water-temperature water-level sensor that the water level sensing accuracy is good.
for solving the problems of the technologies described above, the utility model water-temperature water-level sensor comprises the water-temperature water-level sensing circuit, public electrode, water level induction section and electrically insulating silicone rubber pipeline section, described water level induction section comprises 20% water level induction section, 50% water level induction section, 80% water level induction section and 100% water level induction section, described 20% water level induction section is positioned at the outermost side, public electrode, 50% water level induction section, 80% water level induction section and 100% water level induction section ecto-entad are successively arranged, be connected with electrically insulating silicone rubber pipeline section interval each other, described public electrode, it is outside that each water level induction section and electrically insulating silicone rubber pipeline section are coated on described water-temperature water-level sensing circuit, described public electrode is connected with circuit turn-on respectively with each water level induction section.
Above-mentioned water-temperature water-level sensor, described public electrode and each water level induction section are the electric silica gel section.
Above-mentioned water-temperature water-level sensor, it also includes the support plug, and described support plug is located at the inside of described public electrode, each water level induction section and electrically insulating silicone rubber pipeline section, and described water-temperature water-level sensing circuit is located on described support plug.
The utility model is owing to having adopted technique scheme, it is placed in public electrode the centre of each water level induction section, dwindled the distance of each water level induction section of itself and medial extremity, the sensing sensitivity for each water level in use procedure is all higher, has improved the accuracy of water-temperature water-level sensor work.Public electrode and each water level induction section adopt an electric silica gel section, can make its with the electrically insulating silicone rubber pipeline section between fine and close being connected, the junction is difficult for splitting and leaks, and has avoided water to enter sensor internal, thereby has guaranteed the stability of working sensor.Support plug (as the glass rod or put the epoxy resin rod) and can allow sensor inner core straight elevator, thereby further strengthen the reliability of its support.
