Automatic temperature control system for cleaning nozzle

Abstract

The invention relates to an automatic temperature control system for a cleaning nozzle, and the system comprises an infrared imager which is disposed in a pedestal of a toilet, and is used for carrying out the infrared imaging operation facing the hip of a user, so as to obtain a corresponding infrared imaging image, and outputting the infrared imaging image; a cleaning spray head, arranged in thetoilet lid and used for carrying out spray washing operation on the buttocks of the user; a body temperature analysis device, used for carrying out body temperature analysis on each to-be-analyzed slice to obtain a corresponding slice body temperature, and determining a reference body temperature based on one or more slice body temperatures corresponding to the one or more to-be-analyzed slices;a water temperature adjusting device, used for adjusting the real-time temperature of the cleaning liquid to be sprayed by the cleaning nozzle based on the reference body temperature; wherein the temperature difference between the real-time temperature and the reference body temperature is smaller than or equal to a preset temperature difference threshold value. According to the invention, the comfort level of a user using the closestool can be improved.

Description

technical field [0001] The invention relates to the field of toilet equipment, in particular to an automatic temperature control system for cleaning nozzles. Background technique [0002] The toilet cover integrates warm air drying, warm water washing, drying, and antibacterial. It can effectively reduce anal diseases and bacterial infections in the lower body of all people. It is a comfortable, hygienic, and humanized modern product. After convenience, the intelligent warm water toilet cover sprays warm water to rinse the buttocks, while washing the lower body can eliminate the hygienic troubles of women during menstruation. In winter, the toilet cover can not only heat, but also blow out warm air for drying, which is more helpful for hemorrhoid patients, the elderly, children, and pregnant women, and greatly reduces the incidence of gynecological diseases and anorectal diseases. [0003] When washing the buttocks or the lower body, the nozzle can swing back and forth, whi...

Problems solved by technology

[0004] In order to solve the technical problem in the prior art that the temperature of the cleaning nozzle in the toilet lid cannot follow the body temperature of each user's buttocks, the present invention provides an automatic temperature control system for the cleaning nozzle. On the one hand, it calculates the temperature of each pixel in each image slice The standard deviation of the hue component value is used to select high-value slices to be analyzed based on the size of the standard deviation; on the other hand, based on the body temperature statistical results of multiple slices of the infrared image, the accurate user body temperature is determined, and the spraying of the cleaning nozzle is performed. The temperature is controlled so that the temperature difference between the user's body temperature and the temperature sprayed by the cleaning nozzle is less than or equal to the preset temperature difference threshold, providing more comfortable services for toilet users
