Thermistor sensor used in small appliances
Various NTC thermistor products used in small home appliances have passed the authoritative international product certification: CQC mark certification, UL, C-UL, TUV safety certification. Temperature measurement NTC series thermistors have passed the above-mentioned international product certifications. Among them, MF52, MF51, and MF58 series products have passed AEC-Q200 testing. MF58 series products have passed 100,000 endurance tests in the UL standard. NTC thermistor enterprise management system: The ISO9001 quality management system, TS16949 quality management system, ISO14001 environmental management system, GB/T29490-2013 intellectual property management system, and the integrated management system of industrialization and industrialization are under effective control and efficient operation. The stable performance and reliable quality of NTC thermistor series products have been widely recognized and favored by users.
The utility model discloses a special-shaped NTC thermistor temperature sensor used for water dispensers and small household appliances. Including shell, thermistor body, lead wire and connector. The thermistor body is connected to the connector through a lead wire. It is characterized in that: the thermistor body has an elliptical structure, and the thermistor body is arranged in the shell and is in close contact with the tapered surface at the bottom of the shell, and is encapsulated with epoxy resin. Due to the above-mentioned structural form, the high thermal conductivity encapsulation resin is adopted, the pressing thickness of the thermally conductive aluminum metal piece on the contact surface, the surface curvature of the contact surface, and the elastic force of the contact surface. Apply heat-resistant and thermally conductive silicone grease to the outside of the insulated resistor to improve the response speed. The maximum response time from temperature change-sampling-control-constant temperature action is 10 seconds; Due to the addition of a power switch, excessive temperature will trigger the physical switch action, which not only keeps the water temperature constant, but also makes the electrical equipment safer and more reliable.
Nowadays, small kitchen appliances such as cooking machines, light food machines, IH rice cookers, steam mops, handheld vacuum cleaners, sweeping robots, electric toothbrushes, cleansing instruments, massagers and other personal care appliances have become emerging consumer hotspots. Taking vacuum cleaners as an example, the retail sales of products above 3,000 yuan accounted for the largest proportion, reaching 44.7%, an increase of 10.9% over the same period last year; However, the fastest growth in retail volume is products with RMB 150-200, an increase of about 40%. The latter can already be subdivided into small home appliances for various application scenarios such as car vacuum cleaners and keyboard vacuum cleaners.
