The purpose of this utility model provides a kind ofly can regularly carry out filtering reverse osmosis purifying of drinking water device in limited time.

The purpose of this utility model realizes by following technical scheme, reverse osmosis purifying of drinking water device has fore filter in limited time, reverse osmosis filter, water purification storage narrow-necked earthen jar, it is characterized in that also having and make the water timing controller in limited time, it comprises the timing relay that is connected on the power supply and by the magnetic valve in the water inlet pipe that is connected in fore filter or reverse osmosis filter of this timing relay control.

Water timing controller on also have controlled source socket said the system in limited time, between magnetic valve and fore filter or reverse osmosis filter, also have pressure pump.

The filtering water of desire enters fore filter or reverse osmosis filter by normally closed solenoid valve, water purification is introduced water storage storage narrow-necked earthen jar, when having wanted empty in the narrow-necked earthen jar, pull timing relay by the people, look the one customization water time limit of situation setting in the narrow-necked earthen jar, magnetic valve is opened, can carry out filtration work, then valve cuts out, filtration stops, and water purification storage narrow-necked earthen jar also reaches suitable capacity, has therefore saved and has set up water storage narrow-necked earthen jar certain pressure in the former scheme to close the into process of water, so can shorten working hours, remove the phenomenon of the waste water resource of a large amount of dischargings of condensed water in this process from.Simultaneously, because the pressure water storing tank is not established in its reverse osmosis filter back, make reverse osmosis membrane pressure at both sides difference stable, this pressure difference raises along with water storing tank pressure and reduces unlike existing procucts, cause and produce the water decrease in efficiency, thereby improved product water efficient, also reduced the waste of water resources.

Below, in conjunction with the accompanying drawings and embodiments reverse osmosis purifying of drinking water device in limited time of the present utility model is explained in detail.

Fig. 1 is the prescribe a time limit structure iron of reverse osmosis purifying of drinking water device of the utility model;

Fig. 2 is this schematic circuit of timing controller of reverse osmosis purifying of drinking water device in limited time.

As Fig. 1, reverse osmosis purifying of drinking water device in limited time of the present utility model comprises fore filter 1, reverse osmosis filter 16, it can be that the copper plug also can be a flow control valve for an osmosis filtration Pressure Control Unit 18, the inlet of fore filter connects former water, the inlet of reverse osmosis filter 16 connects the outlet of fore filter, between fore filter 1 and reverse osmosis filter 16 or at the inlet of fore filter 1, be provided with and make water timing controller 5 in limited time, fore filter 1, reverse osmosis filter 16, timing controller 5 can be loaded on the common underframe 12, but also lays respectively, has pipeline to be connected between them, pure water inlet at strainer 16 is connected to water purification storage narrow-necked earthen jar 17, water intaking water tap 13 is arranged on the storage narrow-necked earthen jar 17,, also have liquidometer on the storage narrow-necked earthen jar so that water intaking is used.
