Abstract

The utility model provides a domestic water-saving apparatus, which is composed of a water storage tank and a pressurizing water tank connected with the water storage tank through a water guide pipeline, wherein, the pressurizing water tank can be of a sleeve barrel type; the bottom of an inner barrel body is connected with the bottom of an outer barrel body through a spring. When the inner barrel body is pressed down, water entering the outer barrel body from the water storage tank through the water guide pipeline is discharged along a water outlet pipe under the action of pressure; at that time, the water having pressure loosens the inner barrel body and returns to the original position under the action of the spring. In addition, the pressuring water tank can also be composed of a closed water tank and an air cylinder, the bottom of the air cylinder is provided with a pipeline wit a non-return valve opening onto the closed water tank, and the non-return valve makes gases enter the closed water tank only from the air cylinder. In such a way, the utility model can pressurize the collected secondary water through pressing down the inner barrel body or pedaling down a pedal, making the secondary water have certain pressure in order to attain a favorable flushing effect.

Description

Household water saving device

Technical field: the utility model belongs to household water saving device.

Background technology: at present, freshwater resources day is becoming tight, and it is very important that water-saving technology just seems, the technology that family expenses secondary water utilizes again is a lot, but effective few conscientiously.Be made up of water storage box, outlet pipe, water valve as ZL01237383 " a kind of household water saving device ", the water storage box water inlet is provided with a tapered filter bag, and cotton rope that can be connected to water tank bottom of filter bag central bolt also is provided with one or more layers filtering material in the case.It is used further to flush the toilet after just secondary water being collected, because this secondary water does not have pressure, result of use is undesirable certainly.And another patented technology, this device of ZL99247068 " daily life sewage recovery toilet-flushing apparatus " comprises water tank, water inlet pipe and water outlet pipe, water pump and water pump control circuit composition.Though added the device of feedwater supercharging, but what utilize is water pump, though saved water, but consumed electricity, for family, do not save economically, simultaneously owing to increased by cover water saving fixtures, for the narrow and small family of living, be difficult to make this selection, this also is the reason that this product is difficult to promote.

Goal of the invention: the purpose of this utility model is, a kind of household water saving device is provided, and when increasing secondary water bath pressure, does not need consume electric power again, really reaches the purpose of water saving, saving family expense.

Technical scheme: this household water saving device is by a water storage tank, and forms by the pressurised water tank that conduit pipe links to each other with water storage tank.Water storage tank is used to store secondary water, and there is filter screen on the upper strata, is used for filtering the foreign material of secondary water, and there is blow-off pipe the bottom surface, is used to get rid of the dirt under the precipitation.Pressurised water tank can be telescopic, and the bottom of inside and outside cylindrical shell connects by spring, and aqueduct is communicated with position, outer cylinder body upper end, and outlet pipe is drawn from the outer cylinder body lower end part.When depressing inner barrel, to discharge along outlet pipe under pressure by the water that aqueduct enters outer cylinder body from water storage tank, glassware for drinking water has at this moment had pressure, unclamps inner barrel, is returned to original position under the effect of spring.In addition, pressurised water tank can also be made up of closed tank and air cylinder, and the pipeline of the band one way valve that leads to airtight water tank is arranged at the air cylinder bottom, and one way valve makes gas enter airtight water tank from air cylinder; Have an end to be fixed on the air cylinder top in the air cylinder, the other end is fixed on the spring of an end of expansion link, and expansion link is

Type, an end is connected with spring in air cylinder inside, and is fixing a patch, works the effect of calming the anger, and the other end of expansion link is a pedal in the air cylinder outside; Aqueduct is communicated with closed tank, and outlet pipe is drawn from the closed tank top.When foot pedals, expansion link drives the gas in the patch compression air cylinder, makes it to enter airtight water tank along the pipeline of band one way valve, increases discharge pressure, and when pin unclamped pedal, expansion link was returned to original position under the effect of spring.

Like this,, can give the secondary water of collecting pressurization, make it to possess certain pressure, reach good developing result by depressing inner barrel or depressing pedal.

Beneficial effect: this household water saving device is simple in structure, and cost of manufacture is low, and under the prerequisite that does not increase electricity consumption, use glassware for drinking water and be equipped with certain pressure, and the supercharging of can feeding water as required, flexible and convenient to use.

Description of drawings: Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the another kind of structural representation of the utility model pressurised water tank;

Fig. 3 is the structure chart of air cylinder among Fig. 1;

Fig. 4 is the structure chart of expansion link among Fig. 1.

Embodiment: as shown in Figure 1 and Figure 2, household water saving device is by a water storage tank 1, and forms by the pressurised water tank 2 that conduit pipe 3 links to each other with water storage tank 1, omitted water storage tank 1 among Fig. 2.Water storage tank 1 is used to store secondary water, and there is filter screen on the upper strata, is used for filtering the foreign material of secondary water, and there is blow-off pipe 5 bottom surface, is used to get rid of the dirt under the precipitation.Pressurised water tank 2 can be telescopic, sees Fig. 2, and the bottom of inside and outside cylindrical shell connects by spring 6, and aqueduct 3 is communicated with position, outer cylinder body 7 upper end, and outlet pipe 9 is drawn from outer cylinder body 7 lower end parts.When depressing inner barrel 8, to discharge along outlet pipe 9 under pressure by the water that aqueduct 3 enters outer cylinder body 7 from water storage tank 1, glassware for drinking water has at this moment had pressure, unclamps inner barrel 8, is returned to original position under the effect of spring 6.In addition, pressurised water tank 2 can also be made up of closed tank 10 and air cylinder 11, sees Fig. 1, and the pipeline 13 of the band one way valve 12 that leads to airtight water tank 10 is arranged at air cylinder 11 bottoms, and one way valve 12 makes gas enter airtight water tank 10 from air cylinder 11; Have an end to be fixed on air cylinder 11 tops in the air cylinder 11, the other end is fixed on the spring 15 of an end of expansion link 14, and expansion link 14 is Type, an end is connected with spring 15 in air cylinder 11 inside, and is fixing a patch 16, works the effect of calming the anger, and the other end of expansion link 14 is a pedal 17 in the air cylinder outside; Aqueduct 3 is communicated with closed tank 10, and outlet pipe 9 is drawn from closed tank 10 tops.When foot pedals 17, expansion link 14 drives the gas in the patch 17 compression air cylinders 11, makes it to enter airtight water tank 10 along the pipeline 13 of band one way valve 12, increase discharge pressure, when pin unclamped pedal 17, expansion link 14 was returned to original position under the effect of spring 15.
