Flow detection device and method for bathroom

Abstract

The invention relates to a flow detection device for a bathroom. The flow detection device is arranged in a pipeline of a bathroom accessory and connected with a power generator in the pipeline of thebathroom accessory, and comprises a controller, a power supply circuit and a flow detection circuit; the power supply circuit is connected with the power generator and the controller separately for supplying electric power generated by the power generator to the controller, the flow detection circuit includes a frequency signal collection circuit for collecting rotation frequency signals of the power generator and a voltage signal collection circuit for collecting output voltage signals of the power generator, the frequency signal collection circuit and the voltage signal collection circuit are both connected between the signal collection end of the power supply circuit and the signal input end of the controller, and the flow detection circuit obtains the rotation frequency signals and voltage signals of the power generator and transmits the signals into the controller so that the controller can obtain water flow data through calculation. By means of the flow detection device for thebathroom, the obtained water flow data is more accurate, and the utilization rate of the power generated by the power generator is high.

Description

Technical field [0001] The invention relates to a flow detection device for sanitary ware. The invention also relates to a flow detection method of the flow detection device. Background technique [0002] When using sanitary equipment, the flow of water can be displayed in time, so that users can adjust the flow accurately. In order to ensure safe use and save energy at the same time, a device capable of self-generation for flow display has appeared in the prior art. For example, the Chinese invention patent application "a shower with light feedback flow" with application publication number CN102698898A (application number 201210185033.9), in which the disclosed shower is provided with an impeller in the water cavity, and the water flow enters the water outlet cavity and impacts the impeller to rotate , The impeller rotates to make the power generation circuit generate electricity, and at the same time, the flow data is obtained according to the speed of the impeller. On the on...

AI Technical Summary

Problems solved by technology

On the one hand, the rotational speed of the impeller is related to the speed of the water flow, but the relationship between the speed and the flow rate is not stable

On the other hand, the inertia of the impeller during the movement will also affect the correct display of the flow rate

In addition, the shower cannot generate electricity when the water flow stops. Correspondingly, the data in the memory will be lost due to the power failure after the water is cut off. After the user turns on the shower again, the flow rate before the water is turned off cannot be displayed, and the bathing process cannot be known accordingly.
