The data of flowmeter between core, determine before double discharging type water purifier domestic water water outlets respectively the service life of filter core and
The service life of filter core after domestic water water outlet improves the life tests efficiency of double discharging type filter element of water purifier and accurate
Degree, enables water purifier user to replace filter core in time when filter core service life expires, reduces the failure rate of water purifier, improves
The water quality safety of water purifier improves user and uses the experience of double discharging type water purifiers.
Fig. 3 is the flow diagram of the life detecting method of another filter element of water purifier provided in an embodiment of the present invention, such as
Shown in Fig. 3, on the basis of embodiment shown in Fig. 1, step 102 can specifically include following steps:
S1021, judge whether water flow is greater than setting flow threshold.
Wherein, setting flow threshold can be determined according to the water quality for user's water outlet of living when different water flows.Setting stream
Threshold value is measured, such as can be 3600 liters.
S1022, when water flow is greater than setting flow threshold, before determining in water purifier the first filter core and the first filter core
The service life of filter cores at different levels has expired.
It,, can be with if water flow is less than setting flow threshold when filter core plugging fault occurs in water purifier in the present embodiment
The problem of service life of filter core at different levels has expired before excluding the first filter core and the first filter core, determining filter core, there are quality to ask
There are other problems for topic or water purifier.
S1023, judge water flow velocity whether be greater than zero and be less than setting flow rate threshold, and judge water purifier water pump whether
It is in running order.
In the present embodiment, the life detecting device of filter element of water purifier can while obtaining the data of flowmeter in real time,
Obtain the state of the water pump of water purifier.Sensor etc. can be installed, for detecting the state of water pump on water pump.
S1024, it is greater than zero in water flow velocity and is less than setting flow rate threshold, and when water pump is in running order, determines water purification
The service life of the second filter core has expired in device.
In the present embodiment, as shown in Fig. 2, flowmeter water flow=pure water goes out water flow when water pump is in running order
Amount+waste water drain discharge, this 3 flows of the water purifier of normal work are basicly stable, and as the third level filter core RO service life is reduced,
Flow can gradually become smaller, if flow so indicates the third level filter core RO longevity continuously less than setting flow rate threshold (such as 1L/min)
Life has expired, and user is reminded to change core.
Further, it is zero that the method, which can also include: in water flow velocity, and when water pump is in running order, is obtained
The state for the water supply device being connect with water purifier；When water supply device is in running order, water supply device failure is determined, control is net

On；First filter core is the filter core before domestic water water outlet；Second filter core is the filter core after domestic water water outlet；In water flow
When greater than setting flow threshold, the service life of filter core at different levels has been arrived before determining the first filter core in water purifier and the first filter core
Phase；It is greater than zero in water flow velocity and is less than setting flow rate threshold, and when water pump is in running order, determines the second filter core in water purifier
Service life have expired；In filter core overdue there are service life, prompt information is sent to water purifier user, prompts water purification
Device user replaces filter core, so as to which according to the data for the flowmeter being arranged between the first filter core and the second filter core, difference is true
Before fixed double discharging type water purifier domestic water water outlets after the service life of filter core and domestic water water outlet filter core use
Service life improves the life tests efficiency and accuracy of double discharging type filter element of water purifier, enables water purifier user in filter core
Filter core is replaced when service life expires in time, reduces the failure rate of water purifier, improves the water quality safety of water purifier, improving user makes
With the experience of double discharging type water purifiers.
Fig. 4 is a kind of structural schematic diagram of the life detecting device of filter element of water purifier provided in an embodiment of the present invention.Such as Fig. 4
