Abstract
The utility model discloses a water temperature and water level sensor for solar water heater, which comprises a circuit board, stainless steel sleeve pipes, a thermoplastic pipe and a stainless steel outer sleeve pipe. A water temperature and water level sensing operating circuit is arranged on the circuit board; the stainless steel sleeve pipe is sheathed on the outside of the circuit board with intervals and is communicated with the operating circuit; the thermoplastic pipe is connected between two stainless steel sleeve pipes; the inner parts of the stainless steel sleeve pipe and the thermoplastic pipe are fully filled with epoxide resin in which the circuit board is enclosed. In the using and working process of the sensor of the utility model, water can not soak into the circuit board no matter weather the thermoplastic pipe is aged or damaged, thus the utility model has the advantages of making the water temperature and water level sensing working circuit keep normal work, increasing stability and reliability, avoiding the sensor out of order and ensuring normal service life.
Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of water-temperature water-level sensor that is used on the solar water heater.
Background technology
The water-temperature water-level sensor of solar water heater is arranged in the water tank, be used to detect water temperature and water level in the water tank, its structure comprises wiring board, stainless steel sleeve pipe, thermoplastic tube and stainless steel outer sleeve pipe, stainless steel sleeve pipe spacer sleeve is outside and be connected with water-temperature water-level induction operating circuit on the wiring board at wiring board, and thermoplastic tube is connected between adjacent two stainless steel sleeve pipes.Because long-term the immersion in the water tank, be subjected to that water temperature just changes, water quality Acidity of Aikalinity variation etc. influences, the thermoplastic tube oxidation rate of being made by rubber in the sensor is fast, easily wear out or distortion, thereby make water infiltrate sensor internal from the binding site of thermoplastic tube or it and stainless steel sleeve pipe, make wiring board work malfunctioning, shorten serviceable life.
Summary of the invention
The purpose of this utility model is to propose a kind of solar water heater water-temperature water-level sensor that has reliable and stable serviceability, can guarantee its serviceable life.
For achieving the above object, the utility model solar water heater comprises wiring board, stainless steel sleeve pipe, thermoplastic tube and stainless steel outer sleeve pipe with water-temperature water-level sensor, described wiring board is provided with water-temperature water-level induction operating circuit, described stainless steel sleeve pipe spacer sleeve is connected in described wiring board outside and with described operating circuit, described thermoplastic tube is connected between adjacent two stainless steel sleeve pipes, expire epoxy resin at described stainless steel sleeve pipe and inner filling of thermoplastic tube, described epoxy resin with described wiring board sealing within it.
Because the utility model water-temperature water-level sensor is expired epoxy resin at stainless steel sleeve pipe and inner filling of thermoplastic tube, wiring board is closed, thereby in thermoplastic tube water temperature just changes in the water tank because of being subjected to, water quality Acidity of Aikalinity variation etc. influences oxidation, under the situation of aging or distortion, water can not penetrate into wiring board inside yet, thereby can guarantee the operate as normal of water-temperature water-level induction operating circuit, the stability and the reliability of its induction testing have been guaranteed, avoid working sensor malfunctioning, guarantee the serviceable life of sensor.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the inner structure synoptic diagram of solar water heater with water-temperature water-level sensor.
Embodiment
As shown in Figure 1, solar water heater comprises wiring board 1, stainless steel sleeve pipe 2, thermoplastic tube 3, stainless steel outer sleeve pipe 4 and brass bush 5 with water-temperature water-level sensor, wiring board 1 is provided with water-temperature water-level induction operating circuit, stainless steel sleeve pipe 2 has four, spacer sleeve is in wiring board 1 outside, and is connected with water-temperature water-level induction operating circuit.Thermoplastic tube 3 is made by elastomeric material, and it is used to connect adjacent two stainless steel sleeve pipes 4, is provided with brass bush 5 in the outside of thermoplastic tube 3, and the outside of brass bush 5 is overlapped a thermoplastic tube 3 again.Offer inlet opening 6 on the stainless steel outer sleeve pipe 4, be used for contacting between water and the operating circuit in the water tank.In the inside of stainless steel sleeve pipe 2 and thermoplastic tube 3, fill full epoxy resin 7 with injection system, epoxy resin 7 is with wiring board 1 sealing within it.
