A cleaning filter core alarm signal is displayed when the filtering speed is lower than the lower limit of the designed filtering speed. The water purifier filtering amount and filtering flow detection computer board of the utility model can detect and reflect the using status of the purifier filter core precisely and conveniently.

Description

Water purifier drainage amount, drainage flow detection computer plate

Technical field

The utility model relates to a kind of computer plate, relates in particular to a kind of water purifier drainage amount, drainage flow detection computer plate.

Background technology

Along with industrial expansion, increasing freshwater resources have been subjected to pollution in various degree, and drinking water quality is threatening human healthy.Simultaneously, along with improving constantly of human living standard, drinking water quality is had higher requirement.Therefore, various drink water purifying technology and device have appearred.But common purifier is generally pressed maximum rated water purification amount as index, does not have Presentation Function.Therefore, concerning the ordinary family user, be not easy to grasp the life span of purifier, may cause filter core to lose efficacy, worsen water quality, prestige victimization body health.Or renew cartridge more too early, cause waste.

CN2109601U discloses a kind of water purifier accumulative total timer of working, and by the rated capacity inflow, and the synchro control timer carries out timing the current that flow into water purifier, converts the cumulative throughflow of current to time counting.Mainly comprise timing piece, flowmeter and time switch, in flowmeter, put magnetic float, when reaching rated flow, float to the appropriate location on the magnetic float and open time switch, open timing piece by time switch and make it timing.The weak point of this water purifier timer is and can only works under rated flow, surpasses or can't timing during the deficiency constant flow, time of day that can't the accurate response filter core.In addition, only calculate filter element of water purifier during the life-span with flow (or time), when can not reaction source water change of water quality big to the influence of filter element life.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of water purifier drainage amount, drainage flow detection computer plate that is used for accurately, conveniently reacting the filter element of water purifier user mode.

The utility model water purifier drainage amount, drainage flow detection computer plate comprise one-chip computer and display system, be connected with circuit mode between one-chip computer and the display system, one-chip computer is collected the electric impulse signal of water purifier flow sensor transmission, and calculate water purifier and accumulate drainage amount and drainage rate, when accumulation drainage amount reaches design drainage amount, show more renew cartridge alerting signal, at the bottom of drainage rate, under the design drainage rate, show in limited time and clean the filter core alerting signal.

The utility model water purifier drainage amount, drainage flow detection computer plate adopt single-chip computer with low power consumption, and be battery-powered, and filter core, the filter element life information such as warning that expire are cleaned in LCD liquid crystal display drainage amount, clock, prompting.One-chip computer is handled as calculated to the electric impulse signal of special flow sensor output can detect water purifier drainage amount and drainage rate.The drainage amount of measuring under the good condition of water quality shows more renew cartridge alerting signal when reaching design drainage amount; Do not show cleaning filter core signal under the design drainage rate, prescribe a time limit at the bottom of the drainage rate under the condition of water quality inferiority (when the drainage amount does not reach design objective).

Embodiment

The utility model water purifier drainage amount, drainage flow detection computer plate comprises one-chip computer, display system, setting value input system etc., one-chip computer and display system, the setting value input system, connect with circuit mode between the flow sensor, one-chip computer is collected the electric impulse signal of water purifier flow sensor transmission, and according to the value of setting and electric impulse signal calculating water purifier accumulation drainage amount and drainage rate, when accumulation drainage amount reaches design drainage amount, show more renew cartridge alerting signal, at the bottom of drainage rate, under the design drainage rate, show in limited time and clean the filter core alerting signal.

The water purifier flow sensor comprises float and float limit shaft, and at least 2 little magnetic sheets are set on the float limit shaft, and float is arranged on the float limit shaft with free manner, and float can move up and down along the float limit shaft, and induction chip is set on the float.

On the water purifier flow sensor float limit shaft a plurality of little magnetic sheets are set, the induction chip that is contained on the float moves up and down along the float limit shaft with buoyancy of water, when float during through too small magnetic sheet induction chip send electric impulse signal, one-chip computer receives this electric impulse signal and determines the water yield between two magnetic sheets according to the distance between two magnetic sheets.Float rises with buoyancy of water when adding water, and the umber of pulse that induction chip sends has been represented the corresponding water yield, and one-chip computer is promptly tried to achieve accumulation amount of water (promptly as accumulation drainage amount) with the corresponding water yield addition of umber of pulse.Water purifier begins drainage after adding water, and float slowly descends with water level, sends two pulse signals during through two magnetic sheets, and one-chip computer is according to the interval time of these two signals and the water yield between two magnetic sheets calculating drainage rate.

In the water purifier flow sensor, float is that the material that proportion is lighter than water is made.The float limit shaft is that non-conductive material is made, and is column structure or tubular structure.When the float limit shaft is column structure, can be cylinder, prism etc., the float Freezone is enclosed within float limit shaft outside.When the float limit shaft was tubular structure (barrel top and bottom are provided with through hole, make the inside and outside formation of tube UNICOM), cross-sectional area can be circle, polygon etc., and float freely is placed on float limit shaft tubular structure inside.Little magnetic sheet quantity is at least 2 on the float limit shaft, is generally 4～20, is preferably 8～15, generally should evenly be fixed on the float limit shaft along float limit shaft length direction.

As shown in Figure 2, the utility model water purifier flow sensor is when user mode, and float limit shaft 8 is vertically fixed on the base plate of bucket 3 on the water purifier by axle base 11 and set bolt 12.Several flat thin magnets 5 evenly are set on the float limit shaft 8, and float limit shaft top is provided with limiting plate 4.Float 10 is set on the float limit shaft 8, induction chip 9 is arranged on the float 10, induction chip 9 be connected lead 7 and link to each other, connect lead 7 and be connected with computer plate 6, computer plate 6 receives and handles by the electric signal that connects lead 7 transmission according to setting, and realizes functions such as signal output, control, warning.Lower filter 1 and upper filter 2 are fixed on the water purifier on bucket 3 base plates.

The water purifier flow sensor has following advantage:

1, at the float limit shaft a plurality of little magnetic sheets are installed, induction chip is contained on the float with about the float Mobile, connecting line is few, and cost is low.

2, the flow sensor of many test points compositions can adapt to the operating mode that repeats to add water, and the matching computer plate can Sensed water level, drainage rate, accumulated water volume etc. utilize multi-point water level signal accurate measurement drainage amount prison Survey filter core service life.

3, simple in structure, low-cost applicable to other industry.

4, on special water purifier for drinking machine, use the genus initiative.
