Description

Absolute temperature and humidity sensor with novel structure Technical Field The application relates to the field of sensor technology, in particular to an absolute temperature and humidity sensor with a novel structure. Background The absolute humidity sensor and the absolute temperature sensor are accurately monitored and dynamically regulated in household and commercial high-temperature cooking equipment (such as ovens, steaming ovens, air fryers and the like), so that the cooking effect and the energy efficiency are obviously improved. The absolute temperature sensor detects the temperature of the cavity in real time, avoids uneven heating or overshoot caused by the traditional temperature difference, ensures the food to be heated stably, is especially important to the scenes needing strict temperature control such as baking, baking and the like, and intelligently adjusts the steam quantity or hot air circulation in the steaming, baking or air frying process by analyzing the steam content, so that the humidity inside the food can be maintained, crisp crust can be formed, and the taste and the efficiency are both considered. The cooperative work of the two supports the automatic operation of equipment, reduces manual intervention, reduces energy consumption by optimizing a heating and humidity strategy, prolongs the service life of the equipment, meets the requirements of accuracy, safety and energy conservation in a high-temperature environment, and provides reliable technical support for modern intelligent cooking. The utility model discloses (bulletin) No. CN220854724U, which discloses an absolute humidity sensor, comprising a shell, a bottom cover, a non-sealing thermistor component and a sealing thermistor component, wherein the bottom cover is connected with the bottom of the shell, a cavity is formed between the bottom cover and the shell, the non-sealing thermistor component and the sealing thermistor component are arranged in the cavity between the bottom cover and the shell, two sides of the shell are respectively provided with a first mounting plate, a first mounting hole is formed in the first mounting plate, two sides of the bottom cover are respectively provided with a second mounting plate, a second mounting hole corresponding to the first mounting hole is formed in the second mounting plate, and two ends of a mounting bolt are respectively connected with a mounting nut in a threaded manner. The shell and the bottom cover are spliced together, the mounting bolts penetrate through the first mounting holes and the second mounting holes, the two mounting nuts are respectively mounted at two ends of the mounting bolts, the shell is fixed with the bottom cover, when the shell is required to be separated from the bottom cover, the mounting nuts are separated from the mounting bolts when the parts in the sensor are overhauled and maintained, the sensor is convenient to detach, and the practicability is high.
