Abstract
The utility model discloses a thermistor temperature sensor for a healthcare tea set. The thermistor temperature sensor comprises a shell, a thermistor body, outgoing lines and connectors, wherein the thermistor body is connected with the connectors through the outgoing lines, is arranged in the shell, and is packaged by epoxy resin. The thermistor temperature sensor is characterized in that: the shell has a cylindrical structure; an annular lug boss is arranged on the outer wall of a barrel; and the barrel is 10mm long. The power of the healthcare tea set is times higher than that of an ordinary tea set, and correspondingly, the geometric dimension of the healthcare tea set is larger, so that the temperature control accuracy and safety performance of the healthcare tea set are important. Improvement is made in a metal part shell, and the conventional hardware shell is prolonged by 3mm, so that the high reliability of response to temperature is achieved. Temperature tolerant thermally conductive silicone with high thermal conductivity is coated outside the insulated thermistor, so that response is quickened.
Description
Technical field
The utility model relates to a kind of household electrical appliances and uses thermistor temperature sensor, specifically is a kind of thermistor temperature sensor that is used for the health protection tea set.
Background technology
Existing thermistor temperature sensor; Have following shortcoming: because of the more common tea set power of health tea set is big several times, so the physical dimension of this stove is also corresponding bigger, so its temperature-controlled precision and security performance are important unusually; If with traditional thermistor temperature sensor; Because the length of shell is shorter, and is so the accuracy of temperature detection is relatively poor, safe and reliable inadequately; Because the response speed of traditional thermistor temperature sensor is slow, thus the temperature of hot water can not in time be fed back, thus cause the too high problem that causes hot water always seething with excitement of Yin Wendu.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of safe and reliable, thermistor temperature sensor that is used for the health protection tea set that response speed is fast.
To achieve these goals, the technical scheme of the utility model employing is:
The thermistor temperature sensor that is used for the health protection tea set; Include shell, thermistor body, extension line and connector, the thermistor body is connected with connector through extension line, and said thermistor body is located in the shell; And use epoxy encapsulation; It is characterized in that: said shell is the cylinder assembling structure, and the outer wall of its cylindrical shell is provided with annular boss, and the length of cylindrical shell is 10mm.
The surface of said thermistor body is provided with one deck Kapton, and the surface of Kapton scribbles one deck heat-conducting silicone grease.
Said extension line is provided with protective sleeve.
The beneficial effect of the utility model: because of big several times of the more common tea set power of health tea set; Therefore the physical dimension of this stove is also corresponding bigger; Therefore its temperature-controlled precision and security performance are important unusually; The metalwork shell has been done improvement,, realized high reliability thermotonus with the original handware shell 3mm that extended; Heatproof and the good heat-conducting silicone grease of heat conduction are smeared in resistive element outside after insulation, to improve response speed.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, shell; 2, thermistor body; 3, extension line; 4, connector; 5, epoxy resin; 6, cylindrical shell; 7, annular boss; 8, protective sleeve.
Embodiment
As shown in Figure 1, be used for the thermistor temperature sensor of health protection tea set, include shell 1, thermistor body 2, extension line 3 and connector 4; Thermistor body 2 is connected with connector 4 through extension line 3, and thermistor body 2 is located in the shell 1, and with epoxy resin 5 encapsulation; Said extension line 3 is provided with protective sleeve 8; Said shell 1 is the cylinder assembling structure, and the outer wall of its cylindrical shell 6 is provided with annular boss 7, and the length of cylindrical shell is 10mm.The surface of thermistor body 2 is provided with one deck Kapton, and the surface of Kapton scribbles one deck heat-conducting silicone grease.
The utlity model has following characteristics:
Health tea set in this project adopts high-power heating system, possesses good constant heat dissipation environment in the design, and is higher to the reliability requirement of NTC temperature sensor.This project is carried out the research and development of reliability requirement from the resistive element prescription; In to manganese (50%-65%)-nickel (20%-30%)-iron (20%-30%) system, adding trace elements such as copper, bismuth, neodymium, niobium; Carry out doping vario-property, develop the resistive element of the NTC temperature sensor of highly reliable resistivity-temperature characteristics.2) according to the volume production mould of client's Demand Design handware shell, existing at present client is with my department reach an agreement die sinking trial-production and small lot batch production.3) because of the more common tea set power of health tea set is big several times, so the physical dimension of this stove is also corresponding bigger, so its temperature-controlled precision and security performance are important unusually.For guaranteeing its security performance, the NTC temperature sensor has adopted the 3mm that on original handware shell, extends, and has realized the high reliability to thermotonus.4) health tea set is relatively more difficult with the installing and locating of high reliability NTC sensor module, and we assist the client to solve installation question, let health tea set be immersed in the water with the temp probe of high reliability NTC sensor module, realize the accuracy of temperature detection.5) response speed was fast: less than 10 seconds.For accurately collecting temperature of boiler fast, we have adopted Kapton or the tubing of dielectric strength height and heatproof as the insulation lapping, and the resistive element outside after insulation smears heatproof and the good heat-conducting silicone grease of heat conduction, to improve response speed.6) high conformity, temperature-controlled precision is high: for improving the temperature detection precision, at first thermistor is screened pairing in high precision constant temperature oil groove, guarantee that the consistent performance of sensor is good.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection domain of the utility model.
