Smart toilet seat and method for analyzing user's body composition

Abstract

The invention discloses an intelligent toilet lid and a method for analyzing body compositions of a user. The intelligent toilet lid comprises a seat ring, a plurality of detection electrodes arrangedclose to the front end of the seat ring, an amplification circuit, and a controller. The plurality of detection electrodes are in two groups, to be corresponding to two legs of a user. The pluralityof detection electrodes are used to detect impedance on two sides of a thigh of the user, to output a potential difference signal. A first input end of the amplification circuit is connected with onegroup of the two groups of detection electrodes. A second input end of the amplification circuit is connected with the other group of the two groups of detection electrodes. The amplification circuitis used to perform amplification processing on the potential difference signal, to output a first potential amplifying signal and a second potential amplifying signal. The controller is connected withan output end of the amplification circuit. The controller is used to obtain impedance on two sides of a thigh of the user according to the first potential amplifying signal and the second potentialamplifying signal. Thus, under the condition that a toilet habit of a user is not changed, impedance on two sides of the thigh of the user is accurately detected.

Description

technical field [0001] The invention relates to the technical field of living equipment, in particular to an intelligent toilet cover and a method for analyzing a user's body composition based on the intelligent toilet cover. Background technique [0002] As the popularity of smart toilet seats increases in China, people pay more and more attention to their basic functions and extended functions. Combined with the 2030 Healthy China plan, going to the toilet is a necessary behavior in daily life, and it is very useful to obtain the user's health parameters when the user goes to the toilet. [0003] The related technology proposes a technical way to directly obtain the impedance on both sides of the thigh through two electrode sheets, but the existing problem is that due to the influence of contact impedance, the measurement result is not accurate enough, and at the same time, because the impedance on both sides of the thigh itself is relatively small , so that the contact i...

Problems solved by technology

[0003] The related technology proposes a technical way to directly obtain the impedance on both sides of the thigh through two electrode sheets, but the existing problem is that due to the influence of contact impedance, the measurement result is not accurate enough, and at the same time, because the impedance on both sides of the thigh itself is relatively small , so that the contact impedance has a greater influence on the output result

[0004] The related technology also proposes a technical way to directly obtain the impedance on both sides of the thigh through four electrode sheets, but the existing problem is that one or two electrode sheets will be installed on the armrest, and the measurement process needs to change the user's Toilet habits, measurement is not convenient enough
