Abstract
The utility model discloses an underneath type water temperature and water level sensor which comprises a water temperature and water level sensing circuit, stainless steel sensing pipes, a silica gel section and a supporting bar, wherein the stainless steel sensing pipes are sleeved outside the water temperature and water level sensing circuit with intervals and are respectively communicated and connected with the sensing circuit, the silica gel section is arranged between two neighboring stainless steel sensing pipes, the supporting bar penetrates through the inside of each stainless steel sensing pipe and the silica gel section, the inside of the stainless steel sensing pipes is filled with silica gel, and the silica gel and the silica gel section form a whole through primary die pressing, thereby sealing and wrapping the supporting bar and the sensing circuit inside. The sensor of the utility model can stably stand in a water tank when in use, and can not generate conditions of arbitrary swing or bending and falling, thereby guaranteeing high sensing precision of the water temperature and water level sensor, and the sensor has the advantages of simple structure, low manufacture cost and the like.
Description
Technical field
The utility model relates to a kind of water-temperature water-level sensor, especially a kind of underneath type sensor that is used to detect water-temperature water-level in the solar water heater water tank.
Background technology
Water-temperature water-level sensor is arranged in the water tank of solar water heater, is used to detect water temperature and water level in the water tank.The structure of existing water-temperature water-level sensor generally comprises water-temperature water-level sensing circuit, stainless steel sensor pipe, silica gel section and stainless steel sleeve pipe, stainless steel sensor pipe spacer sleeve also is connected with circuit respectively in water-temperature water-level sensing circuit outside, the silica gel section is connected between adjacent two stainless steel sensor pipes, the stainless steel sleeve pipe is located at the outside of stainless steel sensor pipe and silica gel section, and its top links to each other with the stainless steel sensor pipe of outermost side.The sealing of the sensor that has for guaranteeing that the silica gel section is connected with operating circuit during making, at the inner silica gel fluid that injects of the stainless steel sensor pipe that connects sensing circuit, suppressed with the silica gel section then, makes silica gel and silica gel section form one.But existing sensor is when using as the underneath type sensor (sensor upwards inserts in the water tank from the bottom of water tank), because of its silica gel section softer, sensor is arbitrarily swing even curved in water tank, especially all the more so when water temperature is higher in the water tank, had a strong impact on the accuracy of its water level sensing.
Summary of the invention
The underneath type water-temperature water-level sensor that technical problem to be solved in the utility model is to propose a kind ofly stably to be erected in the water tank, the sensing precision is high.
For solving the problems of the technologies described above, a kind of underneath type water-temperature water-level sensor of the utility model comprises the water-temperature water-level sensing circuit, the stainless steel sensor pipe, silica gel section and support bar, described stainless steel sensor pipe spacer sleeve also links to each other with described sensing circuit conducting respectively in water-temperature water-level sensing circuit outside, described silica gel section is located between described adjacent two stainless steel sensor pipes, described support bar is arranged in each described stainless steel sensor pipe and silica gel intersegmental part, described stainless steel sensor pipe inside is full of silica gel, described silica gel and described silica gel section form one by one-step mould, with described support bar and sensing circuit is airtight be coated in.
Above-mentioned a kind of underneath type water-temperature water-level sensor, the described silica gel section outer cover that is positioned at bottom is provided with the stainless steel supporting sleeve.
Above-mentioned a kind of underneath type water-temperature water-level sensor, the described silica gel section bottom that is positioned at bottom is the flange-like end, the outside of end and a pad crimping are fixed together.
Above-mentioned a kind of underneath type water-temperature water-level sensor, described support bar is the glass rod.
The utility model is owing to adopted technique scheme, and it is equipped with support bar in the inside of each stainless steel sensor pipe and silica gel section, thereby has improved the hardness of sensor greatly.During use, its bottom from water tank upwards inserted water tank after, can stably be erected in the water tank, can not produce random swing or curved situation of falling, thereby guarantee the high sensing precision of water-temperature water-level sensor.Abandoned the stainless steel sleeve pipe that uses in the existing product in the utility model sensor construction, and the stainless steel sensor pipe that will be positioned at both sides is not only simple in structure as public electrode, and cost of manufacture is low.The outside sheathed stainless steel supporting sleeve of sensor lower end silica gel section can further guarantee the vertical support of sensor, and when making, also can save the support bar in this section silica gel section, and technology is convenient.The silica gel section bottom of sensor lower end is adopted flange-like and is crimped with pad, can further simplify syndeton and installation procedure.
