AI Technical Summary

Technical Problem

Traditional liquid fragrance containers cannot dynamically adjust the amount of evaporation according to environmental needs or human activities, resulting in uncontrollable fragrance concentration, small diffusion range, inconvenience of use, and lack of intelligent management.

Method used

Infrared sensors are used to detect human activity, and a microcontroller controls the pump to spray fragrance. A variable-speed fan adjusts the diffusion range, and an electric heating wire heats the liquid fragrance, achieving controllability of range and concentration. A servo motor adjusts the spray direction.

Benefits of technology

It enables controllable range and concentration of fragrances, avoids waste, provides intelligent air freshening management, and adapts to different scenario needs.

Abstract

The present application relates to the field of deodorant, in particular to a liquid spray container with controllable range, which comprises a liquid storage seat, the inside of the liquid storage seat is provided with liquid fragrance, a plurality of reserved openings are formed on the top of the liquid storage seat, a cover is screw-connected to the top end of the liquid storage seat, a pump body is installed below the cover, an atomizing nozzle is fixed to the top surface of the cover, the pump body sucks the liquid fragrance in the liquid storage seat and delivers it to the atomizing nozzle for spraying, a mounting bracket two is fixedly connected to the surface of the liquid storage seat, and an infrared sensing assembly is fixedly arranged in the mounting bracket two; the beneficial effects are that the reserved openings are covered or exposed by the rubber cover, the fragrance volatilization switch is manually controlled, and different scene requirements are adapted; the infrared sensing assembly detects human activity, triggers the pump body to accurately spray, and avoids invalid volatilization; the timer controls the spraying time length, and prevents repeated triggering and waste.
