Abstract

The utility model disclosed a flow sensor for water purifier, which comprises floats and float spacing axles. Two small magnetic sheets are arranged on the float spacing axles. The floats can move up-and-down along the float spacing axles, and inductive chips are arranged on the floats. The inductive chips, which are arranged on the floats, can move up-and-down along the float spacing axles with rising force of water. When the floats go through the small magnetic sheets, the inductive chips produce impulse signals. The floats rise with rising force of water when water is poured into, and pulse number which is produced by the inductive chips stands for corresponding water quantity. The make-up water quantity is achieved after the plus of corresponding water quantity of pulse number. After water is poured into, water is filtered by a purifier. The floats drop slowly with the water level, and produce two impulse signals across two magnetic sheets. Filtration velocity is counted out according to interval time between two impulse signals and water quantity between two magnetic sheets. The utility model has the advantages that cost is low, flexible is wide, and structure is simple. The utility model is applicable for water purifiers and other devices.

Description

The water purifier flow sensor

Technical field

The utility model relates to a kind of sensor, relates in particular to a kind of water purifier flow sensor.

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, real work state 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 flow sensor that can accurately, conveniently react the filter element of water purifier user mode.

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

On the utility model 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, can determine 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 amount of water is promptly tried to achieve in 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, according to the interval time of these two signals and the water yield between two magnetic sheets calculating drainage rate.

The utility model water purifier flow sensor has following advantage:

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

2, the flow sensor formed of many check points can adapt to the operating mode that repeats to add water, but matching computer plate sensed water level, drainage rate, accumulated water volume etc.

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

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

Embodiment

In the utility model 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 on the float limit shaft is at least 2, is generally 4～20, is preferably 8～15, generally should be along evenly being fixed on the float limit shaft on the limit shaft length direction.

As shown in Figure 1, 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 sleeved on the float limit shaft 8 with free manner, induction chip 9 is arranged on the float 10, induction chip 9 be connected lead 7 and link to each other, connecting lead 7 and computer plate 6 links to each other with circuit mode, computer plate 6 receives and handles by the electric signal that connects lead 7 transmission according to setting program, 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.
