Abstract
The utility model discloses a sensor of a solar water heater, which comprises a base (1) and an induction tube (2); the base (1) comprises a plastic cover (3), a plastic sleeve (4) and a circuit board (5); the circuit board (5) is arranged between the plastic cover (3) and the plastic sleeve (4); the induction tube (2) is welded through the circuit board (5) and extends out of the base (1); a ground wire (6) is arranged in the induction tube (2); a thermosensitive resistor (8) is arranged in a thin tube of the internal ground wire (6); the circuit board (5) is provided with gears (7); four or more than four gears (7) are arranged; the circuit board (5) is provided with two devices, i.e. a device with resistor and a device without resistor; part of the plastic sleeve (4) can be thickened; the base (1) can be inserted upwards or downwards. The plastic sleeve and the steel tube or the copper tube are adopted, so the sensor can prevent water from entering, precisely test the water level and temperature without error, and has cost no more than the manufacturing cost of the prior art.
Description
Technical field
The utility model relates to a kind of sensor that is used for solar water heater, particularly a kind ofly prevents into water, water-level and water-temperature is tested accurate sensor for solar water heater.
Background technology
At present, solar water heater is widely used in fields such as hotel, family, hospital, factory, industry, respective government agencies, school, market, and common solar water heater inside is provided with sensor, and sensor can detect water level, water temperature.But, have multiplely on the present sensor for solar water heater market, main water inlet easily has water level, temperature measurement is inaccurate and maintenance is difficult shortcoming, causes the solar water heater product quality bad.Its sensor performance instability, complex process, efficient are low.
The utility model technology
For overcoming the shortcoming that prior art exists, the utility model provides a kind of sensor for solar water heater, has solved easy water inlet, to water level, the inaccurate difficult technical barrier of maintenance that reaches of temperature measurement.
For achieving the above object, the technical solution of the utility model is:
A kind of sensor for solar water heater comprises pedestal 1, induction tube 2, and pedestal 1 comprises vinyl cover 3, plastic jacket 4, circuit board 5, and circuit board 5 is arranged between vinyl cover 3 and the plastic jacket 4; Induction tube 2 is welded by circuit board 5 and stretches out pedestal 1, and it is made that induction tube 2 can adopt stainless steel or copper.Induction tube 2 inside are provided with ground wire 6, and circuit board 5 is provided with gear 7.7 fens four shelves of gear or more than four; Two kinds of devices are arranged on the circuit board 5, and a kind of have resistance, an a kind of non-resistance; But plastic jacket 4 part overstrikings, overstriking can improve performance later.
Compared with prior art, the beneficial effects of the utility model are: owing to adopted plastic jacket and steel pipe or copper pipe, sensor can prevent into water, and water-level and water-temperature is tested accurately, do not had error and cost to be no more than the manufacturing cost of prior art.
Description of drawings
For better understanding the utility model, the spy is illustrated in conjunction with the accompanying drawings.
Fig. 1 is the shape synoptic diagram of the utility model induction tube;
Fig. 2 is the structural representation of the utility model sensor;
Fig. 3 has the circuit diagram of resistance for the utility model circuit board fourth gear;
Fig. 4 is the non-resistance circuit diagram of the utility model circuit board fourth gear.
Among the figure, 1-pedestal, 2-induction tube, 3-vinyl cover, 4-plastic jacket, 5-circuit board, 6-ground wire, 7-gear, 8-thermistor.
Embodiment
In order further to understand the utility model, the spy is illustrated in conjunction with concrete embodiment, but present embodiment can not be thought restriction of the present utility model.
Referring to Fig. 1, the utility model comprises pedestal 1, induction tube 2, and induction tube 2 extends out from pedestal 1, and induction tube 2 is four pipes different in size, and this represents four different gears, and corresponding one by one with the gear 7 of circuit board 5; Among Fig. 2, pedestal 1 and induction tube 2 have been formed sensor, and pedestal 1 comprises vinyl cover 3, plastic jacket 4, circuit board 5, and circuit board 5 is arranged between vinyl cover 3 and the plastic jacket 4; Induction tube 2 is welded by circuit board 5 and extends beyond the pedestal, and it is made that induction tube 2 can adopt stainless steel or copper; Pedestal 1 can adopt plastics or pottery to be made.
This product pedestal in water heater can adopt upper plug type also can adopt down inserting type, but the also overstriking of plastic jacket 4 parts, and overstriking can improve performance later.
