Abstract
The utility model discloses a water temperature & level sensor, which comprises a line fixed plate, a water temperature induction circuit, a water level induction circuit, a signal wire thimble, and a seal rubber sleeve. The line fixed plate is a flat plate to which the water temperature and water level induction circuit is connected, and the exterior of which the seal rubber sleeve is cladded tight. The utility model is simple in structure, convenient to be manufactured and has a long performance life, etc.
Description
Technical field the utility model relates to a kind of water-temperature water-level sensor, in particular for the water-temperature water-level sensor on the solar water heater.
The general rubber that is all coated by inner core and outside sealing of the water-temperature water-level sensor of installing in the existing solar water heater water tank of background technology is formed.Inner core comprises circuit fixed head, water temperature sensor circuit and water level sensor circuit, and sensor circuit is connected on the circuit fixed head.Because the circuit fixed head of existing water-temperature water-level sensor all is T shape or cruciform (referring to shape of cross section), its amount of deflection and elasticity are relatively poor, fracture easily, thereby influence its normal serviceable life.Simultaneously, because the junction of sensor side and signal wire does not have waterproofing design (the signal wire sleeve pipe directly inserts the sensor tail end), easily infiltration.It is variable soft aging in high-temperature water tank to add rubber sleeve, makes the infiltration phenomenon more serious, thereby makes faulty sensor, and serviceable life is short.
The summary of the invention technical problem to be solved in the utility model is to propose a kind of water-temperature water-level sensor of simple in structure, easily manufactured, long service life.
For solving the problems of the technologies described above, the utility model water-temperature water-level sensor comprises circuit fixed head, water temperature sensor circuit, water level sensor circuit, signal wire sleeve pipe and sealing rubber cover, described circuit fixed head is a flat board, described water temperature, water level sensor circuit are connected on the described circuit fixed head, the airtight described circuit fixed head outside that is coated on of described sealing rubber cover.
Above-mentioned water-temperature water-level sensor, described sealing rubber cover is made by silica gel, and the side of described signal wire sleeve pipe and described sealing rubber cover is pressed into one, is suppressed with one deck layer of silica gel on the lateral wall of described signal wire sleeve pipe.
Above-mentioned water-temperature water-level sensor, described water temperature, water level sensor circuit outer cover are provided with guard tube.
The utility model has been owing to adopted above-mentioned technical pattern, changes the shape of circuit fixed head into flat board, and structure is more simple, be convenient to make and produce, the more important thing is that it has strengthened the amount of deflection and the elasticity of circuit fixed head, make its not frangibility, thereby prolonged the serviceable life of water-temperature water-level sensor.Simultaneously, because the side of signal wire sleeve pipe and sealed silicon gum cover is pressed into one, on the lateral wall of described signal wire sleeve pipe, be suppressed with one deck layer of silica gel, and be provided with guard tube in water temperature, water level sensor circuit outer cover, thereby under the effect of multiple tracks waterproof measure, can reach good percolation-proof effect, can effectively avoid faulty sensor, prolong its serviceable life.
Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.
Fig. 1 is the inner structure synoptic diagram of the utility model water-temperature water-level sensor;
Fig. 2 is the back structures synoptic diagram of the circuit fixed head among Fig. 1.
Embodiment as shown in the figure, water-temperature water-level sensor comprises circuit fixed head 1, water temperature sensor circuit 2, water level sensor circuit 3, signal wire sleeve pipe 7 and sealing rubber cover 4, circuit fixed head 1 is a flat board, its upper surface is intervally distributed with silver coating 6 (or copper plate), and the conducting that is used for 5 of water level sensor circuit 3 each resistance connects.The two ends of each spring 10 are welded on the circuit fixed head 1, and water temperature sensor circuit 2 and water level sensor circuit 3 are connected on the circuit fixed head 1.Each resistance 5 and water temperature sensor circuit outside are arranged with guard tube 11,12 respectively.Sealing rubber cover 4 is made its airtight outside that is coated on circuit fixed head 1 by silica gel.Signal wire sleeve pipe 7 is made by stainless steel, and the side of one end and sealing rubber cover 4 is pressed into one, and silica gel is pressed into the inside of signal wire sleeve pipe 7.Be suppressed with one deck layer of silica gel 8 on the lateral wall of signal wire sleeve pipe 7 in addition.Among the figure, 9 expression signal wires.
