Abstract
The utility model relates to a water and electricity conducting type sensor for water levels and water temperatures, which comprises a casing body, a thermosensitive resistor, electricity conducting silica gel and resistors, wherein, the casing body is divided into an upper part and a lower part, a water inlet hole is arranged on the lower casing body, and at least two pieces of electricity conducting silica gel which are arranged vertically and are spaced with the same distance, and the encapsulated thermosensitive resistor and a conducting wire thereof are arranged inside the lower casing body; the resistors with the quantity corresponding to the quantity of the electricity conducting silica gel are arranged inside the upper casing body, and the conducting wire is arranged on each piece of electricity conducting silica gel and is respectively connected with the corresponding resistor. The utility model has the advantages of no scale deposit, sensitive response, no water seepage, and long service life.
Description
Technical field
The utility model relates to a kind of and the supporting water-level and water-temperature sensor of water-temperature water-level intelligent controller solar water heater, especially a kind of water power conduction type water-level and water-temperature sensor.
Technical background
Solar water heater water tank is a special environment, and water temperature is sometimes cold and sometimes hot, thereby the sensitivity of the water-level and water-temperature sensor that the is placed in one major issue that become many producers to solve with serviceable life.What be used for the water-level and water-temperature sensing at present has several water-level and water-temperature sensors such as pressure type, magnetoelectric induction and water power conduction type, and pressure type sensor places water tank bottom, and summer high temperature makes the water level error in judgement after causing the water boiling easily; Magnetoelectric induction sensor is the band permanent magnet ball float that places water, following water-level lifting, make the sensing element of sensor internal produce signal, the input main frame shows SEA LEVEL VARIATION, but it when also existing the water tank water temperature higher magnetic weaken disadvantage with malfunctioning, the water tank water spray uncontrollable of element with supreme water; Existing water power conduction type water-level and water-temperature sensor, be with inside be packaged with thermistor or conventional, electric-resistance, the outside has the sensor of a plurality of hard contacts to place water tank, utilize the resistance detection water level, but after using a period of time, outside hard contact reacts malfunctioning because of scaling, and inner element is again because of infiltration short circuit reduction of service life; Though the product that has adopts electric silica gel to replace hard contact,,, infiltration still exists because of causing the problem of product shortening in serviceable life to avoid scaling.
Summary of the invention
The purpose of this utility model provides a kind of not scaling, is quick on the draw, and does not have seepage problem, the water power conduction type water-level and water-temperature sensor of long service life.
For realizing above purpose, water power conduction type water-level and water-temperature sensor of the present utility model comprises housing, thermistor, electric silica gel and resistance, described housing divides the upper and lower part, lower house is provided with the inlet opening, be provided with in the lower house upper and lower settings at interval same distance at least two electric silica gels and through the thermistor and the lead thereof of encapsulation, be provided with quantity and the corresponding resistance of electric silica gel quantity in the upper shell, have lead continuous with corresponding resistance respectively on each electric silica gel.
Described housing bottom is provided with weight.
Described housing bottom is provided with the inlet opening.
The conduction type water-level and water-temperature sensor of the utility model structure utilizes electric silica gel to solve the influence that scaling brings as conductive contact, and sensor in use is quick on the draw all the time; Especially will measure the resistor group of water level and be located at outside the water tank, prolonged the serviceable life of product greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in the figure, conduction type water-level and water-temperature sensor of the present utility model comprises housing 1, thermistor 3, electric silica gel 5 and resistance 4, housing 1 is divided into two parts up and down, the bottom of housing 1 is located in the water tank, and top places outside the water tank, and lower house is provided with inlet opening 2, be provided with thermistor 3 and lead thereof in the lower house, thermistor 3 is through the heat-conducting glue encapsulation, and it and it lead is access to the water-temperature water-level display through upper shell and shows water temperature again through the heat-shrinkable T bush encapsulation; Electric silica gel 5 also is located in the lower house, its quantity that is provided with is decided according to water level class to display, adopting more is that fourth gear water level or five grades of water levels are set, if five grades of water levels are set, just the interval same distance is provided with five electric silica gels 5 from top to bottom, is equipped with lead on the every electric silica gel 5.Resistance 4 is located at the top of housing, it be provided with quantity and electric silica gel 5 corresponding and respectively be connected electric silica gel 5 on lead link to each other, every electric silica gel place behind the water tank water intake will show one grade of water level on the water level display like this.Floating in order to prevent this sensor, be provided with weight 7 in the bottom of housing, and have inlet opening 6 in the bottom.
Claims (3)
