Abstract
The utility model discloses a water temperature and water-level sensor of a water heater. The water temperature and water-level sensor comprises a water temperature and water-level sensing circuit, a stainless steel common electrode tube, stainless steel water level induction pipes, insulating silica gel pipes and stainless steel fixing pipes, wherein the stainless steel common electrode tube is arranged on the outermost side end and is conducted and connected with the water temperature and water-level sensing circuit, the stainless steel water level induction pipes are sleeved outside the water temperature and water-level sensing circuit and is conducted and connected with the water temperature and water-level sensing circuit, the end parts of the insulating silica gel pipes are respectively sleeved outside side ends of the stainless steel water level induction pipes and the stainless steel common electrode tube in sealed connection, the stainless steel fixing pipes are tightly sleeved and fixed outside connecting ends, and silica gel is filled in the stainless steel common electrode tube, the stainless steel water level induction pipes and the insulating silica gel pipes. Therefore, joints of the insulating silica gel pipes, the stainless steel common electrode tube and the stainless steel water level induction pipes are not easy to crack and leak, and the water is prevented from entering into the interior of the sensor, thereby the work stability of the sensor is guaranteed, and the service life of the sensor is prolonged.
Description
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, its structure generally comprises the water-temperature water-level sensing circuit, stainless steel public electrode pipe, stainless steel water level induction tube and Silicon-On-Insulator sebific duct, stainless steel water level induction tube spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside, the Silicon-On-Insulator sebific duct is connected between adjacent two stainless steel water level induction tubes, stainless steel public electrode pipe, stainless steel water level induction tube and Silicon-On-Insulator sebific duct inside are full of silica gel, silica gel and Silicon-On-Insulator sebific duct form one.Stainless steel public electrode pipe is positioned at the outermost side, and its medial extremity closely is connected with the Silicon-On-Insulator sebific duct.In use procedure, because the two ends of Silicon-On-Insulator sebific duct are enclosed within on the outer wall of stainless steel water level induction tube and stainless steel public electrode pipe, and silica gel is softer, easily splitting and cause into water in the junction of Silicon-On-Insulator sebific duct and stainless steel sensor pipe, thereby has affected the normal work and use life-span of water-temperature water-level sensor.
Summary of the invention
Technical problem to be solved in the utility model is to propose the water-temperature water-level sensor of the water heater of a kind of good operating stability, long service life.
for solving the problems of the technologies described above, the water-temperature water-level sensor of a kind of water heater of the utility model comprises the water-temperature water-level sensing circuit, stainless steel public electrode pipe, stainless steel water level induction tube, Silicon-On-Insulator sebific duct and stainless steel stationary pipes, described stainless steel public electrode pipe is positioned at the outermost side and with the conducting of described water-temperature water-level sensing circuit, is connected, described stainless steel water level induction tube is set in described water-temperature water-level sensing circuit outside and with the conducting of described water-temperature water-level sensing circuit, is connected, described Silicon-On-Insulator sebific duct is located between adjacent two described stainless steel water level induction tubes and is reached between adjacent described stainless steel public electrode pipe and stainless steel water level induction tube, the outside also sealing of side that the end of described Silicon-On-Insulator sebific duct is sheathed on respectively described stainless steel water level induction tube and stainless steel public electrode pipe is connected, described stainless steel stationary pipes is locked and is fixed on the outside of link, described stainless steel public electrode pipe, fill with colloidal silica in stainless steel water level induction tube and Silicon-On-Insulator sebific duct.
The utility model is owing to having adopted technique scheme, it Silicon-On-Insulator sebific duct section and stainless steel public electrode pipe, stainless steel water level induction tube be connected end again the outer casing stainless steel stationary pipes overlapped and fastened, thereby the junction of Silicon-On-Insulator sebific duct and stainless steel public electrode pipe, stainless steel water level induction tube is difficult for splitting and leaks, avoided water to enter sensor internal, thereby guaranteed the stability of working sensor, extended its serviceable life.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.
