Abstract
The utility model discloses a underneath-type water temperature and water level sensor. The sensor comprises a water temperature and water level sensing circuit, sensing electrodes, an insulating segment and a flange end. Each sensing electrode sleeves an outer portion of the water temperature and water level sensing circuit with intervals and is conductively connected with the water temperature and water level sensing circuit respectively. The insulating segment is a hard plastic pipe. And the hard plastic pipe is fixedly connected between the two adjacent sensing electrodes respectively. Each sensing electrodes and the internal portion of the hard plastic pipe are filled with silica gel. The flange end is fixedly connected to the hard plastic pipe of an innermost side end. The water temperature and water level sensing circuit passes through the flange end. The sensor of the utility model can keep a straight working condition, working is stable and reliable and the service life is long.
Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, specifically a kind of underlying sensor for detection of water-temperature water-level in water heater especially solar water heater water tank.
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.Underneath type water temperature-level sensor upwards stretches into water tank inside from bottom, its structure generally comprises water-temperature water-level sensing circuit, induction electrode, insulating segment and flange end, induction electrode spacer sleeve is also connected with circuit turn-on respectively in water-temperature water-level sensing circuit outside, and insulating segment is connected between adjacent two induction electrodes.Because insulating segment generally all adopts silica gel material, make, belong to flexible material, water-temperature water-level sensor easily bends at this place.Meanwhile, the insulating segment of flexible material also makes sensor can not keep straight state always, has influence on the accuracy of working sensor.In addition, because induction electrode generally all adopts stainless-steel tube, use is easily responded to the insensitive phenomenon even losing efficacy because of surface dirt long afterwards, and then has influence on the steady operation of water-temperature water-level sensor.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of energy and keeps straight duty, and working stability is reliable, the underneath type water temperature-level sensor of long service life.
For solving the problems of the technologies described above, a kind of underneath type water temperature-level sensor of the utility model comprises water-temperature water-level sensing circuit, induction electrode, insulating segment and flange end, described each induction electrode interval is placed on described water-temperature water-level sensing circuit outside and is connected with the conducting of described water-temperature water-level sensing circuit respectively, described insulating segment is hard plastic tube, described hard plastic tube is fixedly connected on respectively between adjacent two described induction electrodes, described each induction electrode and hard plastic tube inside are full of silica gel, described flange end is fixedly linked with the described hard plastic tube of medial extremity, described water-temperature water-level sensing circuit is through described flange end.
Above-mentioned a kind of underneath type water temperature-level sensor, it also includes conduction sebific duct, and described conducting resinl pipe box is located at the outside of described each induction electrode, interference fit mutually between the two, one end of described conduction sebific duct and one end of described hard plastic tube are fixedly linked.
Above-mentioned a kind of underneath type water temperature-level sensor, convexes with respectively step on the inside pipe wall of the both sides of described hard plastic tube, the side of described induction electrode is against on described step.
The utility model is owing to having adopted technique scheme, insulating segment has adopted hard plastic tube, has both played the effect that induction electrode is separated in insulation, can not make again sensor bend at this position, use and also can not produce crack long afterwards, guaranteed the serviceable life of sensor.Meanwhile, the hard plastic tube of usining also makes sensor can keep straight state as insulating segment always, has guaranteed working sensor quality.In the outside of induction electrode, connect conduction sebific duct, can induce dual guarantee effect to water level, even if use long afterwards, also can, because induction electrode surface dirt causes responding to insensitive even inefficacy, not guarantee the job stability of water-temperature water-level sensor.
Accompanying drawing explanation
Fig. 1 is the external structure schematic diagram of the utility model underneath type water temperature-level sensor;
Fig. 2 is the syndeton schematic diagram of induction electrode in Fig. 1, insulating segment and conduction sebific duct.
Embodiment
As shown in Figure 1, the utility model underneath type water temperature-level sensor comprises water-temperature water-level sensing circuit 5, induction electrode 1, insulating segment 2, conduction sebific duct 3 and flange end 6, and each induction electrode 1 interval is placed on water-temperature water-level sensing circuit 5 outsides and is connected with 5 conductings of water-temperature water-level sensing circuit respectively.Insulating segment 2 is hard plastic tube, is fixedly connected on respectively between adjacent two induction electrodes 1, and each induction electrode 1 and hard plastic tube 2 inside are full of silica gel.Conduction sebific duct 3 is sheathed on the outside of each induction electrode 1, interference fit mutually between the two, and conduction one end of sebific duct 3 and one end of hard plastic tube 2 are fixedly linked by gummed mode.Induction electrode 1 comprises public electrode and water level induction electrode, and public electrode is positioned at outermost side, and its medial extremity is closely connected with conduction sebific duct 3 interference fit.Flange end 6 is fixedly linked with the hard plastic tube 2 of medial extremity, and water-temperature water-level sensing circuit 5 is through flange end 6.
As shown in Figure 2, convex with respectively step 21 on the inside pipe wall of the both sides of hard plastic tube 2, the side of induction electrode 1 is against on step 21, has both been convenient to assembling, also can guarantee the steadiness connecting.Between induction electrode 1 and hard plastic tube 2, can be fixedly linked by gummed mode.
