Embodiment 1

[0030] Filter element life indicator device with automatic water cut-off function, such as Figure 1-Figure 8 As shown, it also includes a controller 320, a water shut-off solenoid valve 1 and a filter element life indicator 3 connected to the filter element 2. The filter element life indicator 3 is provided with a flow collection device 31, and the filter element life indicator 3 includes an indicator upper cover 314 and The indicator lower cover 315, the flow collection device 31 is located between the indicator upper cover 314 and the indicator lower cover 315, the indicator upper cover 314 is provided with a display screen connected to the controller 320 and used to indicate the life of the filter element 2, and the control The controller 320 controls the display screen to display the service life of the filter element 2 according to the received flow signal. A battery slot 316 is provided at the bottom of the indicator lower cover 315, and a battery 317 for power supply i...

Embodiment 2

[0042] The flow acquisition device 31 also includes a counting chip and a frequency-current conversion circuit. The frequency-current conversion circuit is used to convert the pulse signal generated by the preamplifier into an analog current to obtain an instantaneous flow value. The counting chip is used to accumulate the instantaneous flow value. Get the cumulative flow value. The pulse signal is sent to the frequency current conversion circuit, the pulse signal is converted into an analog current, and then the instantaneous flow value is indicated, and the accumulated flow value obtained by the low-power counting chip is accumulated, and the accumulated flow value obtained by recording is displayed on the LCD frequency.

Abstract

The invention relates to water purification equipment, and discloses a filter element life indicating device with an automatic water cut-off function. The filter element life indicating device comprises a controller (320), a water cut-off electromagnetic valve (1) and a filter element life indicator (3) connected with a filter element (2); a flow collecting device (31) is arranged in the filter element life indicator (3) and used for collecting the actual water flow of the filter element (2) and sending a collected flow signal to the controller (320), and the controller (320) is used for processing the received flow signal, comparing the received flow signal with a flow upper limit value set in the controller and controlling the water cut-off electromagnetic valve (1) according to a comparison result. According to the filter element life indicating device, whether the filter element life is expired or not is judged by collecting the actual water flow of the filter element, and the purified water consumption of a user can be intelligently reflected; meanwhile, when the filter element life is expired, a water source can be cut off in time, and the machine is stopped to stop water production; the advantages of being low in cost and capable of effectively ensuring safe water usage of the user.

Description

technical field [0001] The invention relates to water purification equipment, in particular to a filter core life indicating device with automatic water cut-off function. Background technique [0002] Due to the pollution and deterioration of China's water quality, the demand for household water purifiers for RO machines is increasing, and many non-electric and pump-free water purifiers are increasing, especially some non-electric UF ultrafiltration machines and some simple filter systems. There are problems such as no record of water volume, and some products with records only use the date and time of use to calculate the time for the next replacement of the filter element, which cannot reflect the actual water flow of the filter element. As a result, the life of the filter element has been greatly exceeded, and the user continues to drink, so that a large amount of unsafe drinking water is misused, and the use of the water purifier seriously affects the health of the peopl...
