Abstract

The utility model relates to a wash-free lower water box; a water sac is arranged in the water box, a water inlet and a water outlet of the water sac are directly connected to inlet water and outlet water by the water inlet and the water outlet of the water box. Water directly enters into the water sac and operates in the totally-enclosed environment. In this way, the water is completely isolated from the medium such as ambient air, and the like, which completely prevent sundries such as dust, and the like, from entering into water and polluting water quality. At the same time, a filter is arranged at the water inlet to keep the water in the water sac clean and avoid the regular cleaning work for the water tank as the water quality is guaranteed to be free from influence of pollution, sundries, etc.

Description

A kind of water tank

One: technical field

The present invention relates to a kind of in supply and drain water system, use exempt to clean water tank, particularly a kind of lower water box that is installed on low level.

Two: background technology

Lower water box in the prior art is because it is in a kind of open architecture, water in the water tank can not be isolated fully with media such as outside airs, thereby make the water electrode that stores in the water tank be vulnerable to secondary pollution, dust and foreign material etc. also enter in the water easily simultaneously, time has deposited a lot of sediments etc. in long water tank, in order to guarantee the cleaning of water tank, the water tank of this structure must regularly clean in the process of using, so just cause the consumption of lot of manpower and material resources, in the process of cleaning, also must cut off the water 1-2 days simultaneously, influence people's normal life order.

Three: summary of the invention

The objective of the invention is to: design a kind of totally enclosed lower water box, it need not be cleaned, stop water pollution once again, and install simply, health safe in utilization is reliable.

The following structure of this novel employing realizes above-mentioned purpose, water tank comprises: tank shell, water pocket, the water pouring device, liquid level sensor, air inlet and outlet device, strainer, motor operated valve etc., on the shell of water tank, have and the import of intaking and being connected, water inlet is connected with motor operated valve, motor operated valve is connected with strainer, on the shell of water tank, also have the mouth of pipe that is connected with water outlet and water draw-off, water pocket is installed in the tank shell, on water pocket, have simultaneously the effluent pipe mouth that is connected with water outlet, this mouth of pipe is connected with delivery port and pressure relief device by the effluent pipe mouth of water tank, on water pocket, open and also have the water inlet pipe mouth that is connected with water inlet, this mouth of pipe is connected with water inlet by the water inlet pipe mouth of water tank, liquid level sensor is installed in the water pocket by water tank, at the top of water tank air intake and exhaust system is installed.

Adopt as above structure, because water pocket has been installed in water tank, the intake-outlet of water pocket directly is connected with Inlet and outlet water by the intake-outlet of water tank, water directly enters in the water pocket, water is in the environment of totally-enclosed and moves, like this water just and medium such as outside air isolate fully, thoroughly having stopped dust and other impurities enters in the water, cause pollution to water quality, simultaneously strainer also has been installed at water inlet, make the water that enters in the water pocket be in clean state, avoided the timing that water tank carries out being cleaned because of the influence that guarantee that water quality is not contaminated, foreign material etc. enters.

Five: the specific embodiment

Exempt to clean lower water box; comprise: water tank 1; water pocket 2; rush down pressure device 3; one way valve 4; liquid is sensor 5; air intake and exhaust system 6; strainer 8; motor operated valve 13 etc.; Fig. 2 is this novel enforcement user mode figure; water tank 1 has water inlet 7 and is connected with one way valve 4; the other end of one way valve 4 is connected with motor operated valve 13; the other end of motor operated valve 13 is connected with strainer 8; the other end of strainer 8 is connected with water inlet pipe (not marking among the figure); water pocket 2 is installed in the water tank 1; the water inlet 11 of water pocket 2 is connected with the water inlet 7 of water tank 1; water just can enter in the water pocket 2 like this; when water enters in the water pocket 2; water pocket 2 expands automatically increases the storage level of water; because water pocket 2 is in air-tight state; water has just been avoided and the contacting of media such as outside air; avoided the secondary pollution of water quality; water tank 1 also has delivery port 10; the mouth of pipe 12 that delivery port 10 is connected with user's outlet pipe (not marking among the figure) respectively; with be connected with pressure relief device 3; because one way valve 4 is installed at water inlet 7 places; water can only flow to the user by delivery port 10; avoided water in the water pocket 2 by water inlet 7 backflow phenomenons; water pocket 2 shrinks automatically water is flowed freely during user's water; exhauster device 6 is connected with water tank 1 simultaneously; air when water pocket 2 expands or shrinks between water pocket 2 and the water tank 1 sucks or discharges; avoid water tank 1 to damage unusually because of vacuum etc. occurring; liquid level sensor 5 is installed in the water pocket 2 by connecting hole 9; control motor operated valve 13 is opened for water pocket 2 moisturizings when the water level in the water pocket 2 is low like this; when water pocket 2 middle water levels are in high water level, close motor operated valve 13 and stop into water; delivery port 10 is connected with pressure relief device 3; when surpassing the high water level setting value, opens automatically the water level of water pocket 2; water in the water pocket 2 is emitted by pressure relief device 3 by delivery port 10; protection water pocket 2 and water tank 1 are not damaged; at the water inlet end of water tank 1 strainer 8 has been installed; the water that has guaranteed to enter in the water pocket 2 does not have impurity to enter; it is airtight that whole water supply process is in fully; move in the free of contamination environment; avoided cleaning a large amount of manpowers that consumed because of roof tank water quality pollutes; the waste of material resources, the while has also guaranteed the safety of people's waters; clean; health.
