Problems solved by technology

[0003] The realization of the above functions requires the flow detection to achieve fast detection speed and high detection accuracy, otherwise the excessive detection error will cause serious deviations in the calculation of the life of the filter element, and then cause malfunctions
If it is used for value-added services, it also affects the user experience
As for the detection speed, if the detection speed is slow, when the user wants to know the real-time traffic information, it cannot be displayed in time, making the user wait, which will also affect the user experience

Abstract

The invention discloses a flow detection method, a flow detection device and a water purification device. The flow detection method is applied to flow meters and is characterized by including the steps: detecting pulse widths of pulse signals sent by a sensor of the flow meter by a set time interval; calculating subtotal flow rates within the time interval according to the pulse widths; obtaining a total flow rate by summing up the subtotal flow rates from the time when liquid passes through the flow meter to the time when the liquid stops flowing through the flow meter. By adoption of the flow detection method, detection speed can be increased while detection precision can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of flow measurement, and in particular to a flow detection method, a flow detection device, and a water purification device provided with the flow detection device. Background technique [0002] In related technologies, a flow detection function is usually added to water purification products, mainly to assist in calculating the life of the filter element and accumulating the filtered water volume of the filter element. In today's intelligent home appliances, in intelligent water purification products, the detection of the purified water flow used by users is also used to provide users with value-added services, such as statistics of users' daily purified water consumption and total water consumption. [0003] Realizing the above functions requires the flow detection to achieve fast detection speed and high detection accuracy, otherwise the excessive detection error will cause serious deviations in ...
