Water cup capable of automatically judging water drinking amount

Abstract

In order to improve the detection precision of the water drinking amount, the invention provides a water cup capable of automatically judging the water drinking amount. The water cup comprises a water cup body, and further comprises a plurality of pressure sensors, a plurality of liquid level sensors, a three-dimensional acceleration sensor, a horizontal sensor, a plurality of infrared sensing units and a water drinking amount computing unit, wherein the plurality of pressure sensors are arranged on the bottom and the side walls of the water cup body; the plurality of liquid level sensors are arranged on the side walls of the water cup body; the three-dimensional acceleration sensor is arranged on the bottom of the water cup body; the horizontal sensor is arranged on the bottom of the water cup body; the plurality of infrared sensing units are arranged on the top and the side walls of the water cup body; the water drinking amount computing unit is arranged on the bottom of the water cup body, and the water drinking amount is obtained according to the detection results of the pressure sensors, the liquid level sensors, the three-dimensional acceleration sensor, the horizontal sensor and the infrared sensing units.

Description

technical field [0001] The invention relates to the technical field of daily necessities, more specifically, to a water cup for automatically judging the amount of drinking water. Background technique [0002] Water plays an important role in maintaining our life. With the popularization of health knowledge and the improvement of people's awareness of health preservation, people pay more and more attention to the amount of drinking water and the health of drinking water, especially the health effect of warm boiled water. The planning and management of the long-term intake of water puts forward higher requirements for the real-time temperature of the daily intake of water and the actual intake of water. [0003] The publication number is CN104367121A, and in the patent titled the water cup measuring system for detecting the amount of drinking water, a gravity sensing sheet is set at the center of the bottom of the water cup body to measure the weight in the cup, and the meas...

Problems solved by technology

[0003] Publication No. CN104367121A, in the patent titled Water Cup Measuring System for Detecting Drinking Water, the center of the bottom of the water cup body is provided with a gravity sensing sheet to control the amount of water in the cup. The weight of the cup is measured, and the measurement result is sent to the mobile phone for collection. However, when the cup is slightly tilted, the pressure sensor at the bottom of the cup has a large error. Collecting wrong data for a long time, accumulating over time, can easily cause a series of health problems

[0004] The publication number is CN203506280U, and the name is a patent for a water cup for detecting the amount of drinking water. There is a through hole in the center of the bottom of the cup body, and the water depth sensor is placed in the hole. Precisely cooperate with the hole, the water level sensor is used to detect the amount of water in the cup. When the cup is tilted, the height of the water in the cup is relatively low. The water level sensor located in the center of the cup body cannot sense this part of the water, and will not be able to absorb this part of the water. Measured out, there are also hidden dangers that lead to health problems

[0005] That is to say, the measurement errors of the existing drinking water cups are relatively large
