Summary of the invention
The purpose of this utility model provides a kind of water-saving cistern that can control water yield.
The utility model is achieved through the following technical solutions: a kind of water-saving cistern, comprise storage tank, ball float, water inlet pipe, overflow pipe and outlet pipe, described outlet pipe is contained in the storage tank bottom, the upper port place of outlet pipe is hinged with the skin plug, skin is equipped with stay cord beyond the Great Wall, the other end of stay cord links to each other with the control assembly that is contained in the storage tank outside, an arm that communicates with it is arranged on outlet pipe, arm passes the storage tank base plate, its upper port is positioned at water tank and is higher than the upper port of outlet pipe, upper port place at arm is hinged with the skin plug, and skin is equipped with stay cord beyond the Great Wall, the other end of stay cord be installed in the storage tank outside on control assembly link to each other.
Described control assembly is the knob that is contained on the storage tank outer wall.
The upper end of described arm is connected with flexible pipe, and described skin plug is hinged on the upper port place of flexible pipe, between the inwall of flexible pipe and storage tank arrangement for adjusting height is housed.
Described adjusting device comprises that one is packed in the support on the storage tank inwall, and the front end of support is hinged with pole, and pipe clamp is housed on the pole, and pipe clamp is sleeved on the upper port place of flexible pipe, between pole and the storage tank inwall adjusting rod that can regulate the flexible pipe height is housed.
Described adjusting rod is made up of positive screw mandrel, anti-screw mandrel, silk tube and locking nut, wherein positive screw mandrel one end is installed on the pole, and the other end screws in the silk tube, and an end of anti-screw mandrel is installed on the storage tank inwall, the other end screws in the silk tube, all is combined with locking nut on positive screw mandrel and anti-screw mandrel.
Adopt above-mentioned structure, owing on the outlet pipe on the storage tank, connect an arm that communicates with it, the top of arm is positioned at the storage tank body and is higher than the upper port of outlet pipe, so the user can reach the purpose of water saving according to the different situations selection waterdrainage amount of excrements.In order to reach better effect, can adorn a flexible pipe in the upper end of arm, the adjusting device that can carry out height is housed between flexible pipe and the storage tank inwall, can be by the adjusting of flexible pipe height being controlled the water yield of emitting.This water-saving cistern is compact conformation not only, but also does not take other space, just simply transforms the purpose that can reach water saving on the basis of existing water tank.
The specific embodiment
As shown in the figure, water inlet pipe 19 and overflow pipe 14 are housed in storage tank 1, float valve 13 and ball float 12 are housed on the water inlet pipe 19.Outlet pipe 18 is housed on the base plate of storage tank 1, and outlet pipe 18 is equipped with O-ring seal with the junction of base plate.Upper port place at outlet pipe 18 is hinged with skin plug 17, and stay cord 16 is housed on the skin plug 17, and the other end of stay cord 16 links to each other with knob 3 on being installed in casing 1 outer wall.The mode that skin plug 17 is opened also can on storage tank 1, cover be provided with one link to each other with stay cord 16 carry button.Being positioned on the outlet pipe 18 of storage tank 1 below has a coupled logical arm 10, and arm 10 passes storage tank 1 base plate, and its upper port is positioned at storage tank 1 and is higher than the upper port of outlet pipe 18, and arm 10 is equipped with O-ring seal with the junction of base plate.The upper end of arm 10 is connected with flexible pipe 20, and the hinged skin plug 5 in the upper port place of flexible pipe 20 is equipped with stay cord 4 on the skin plug 5, and the other end of stay cord 4 links to each other with knob 2 on being installed in storage tank 1 outer wall.The mode that skin plug 5 is opened also can on storage tank 1, cover be provided with one link to each other with stay cord 4 carry button.Adjusting device also is housed between the inwall of flexible pipe 20 and storage tank 1, and this adjusting device is to be fixed with support 7 on storage tank 1 inwall, and the front end of support 7 is hinged with pole 6, and pipe clamp 11 is housed on the pole 6, and pipe clamp 11 is sleeved on the upper port place of flexible pipe.Also be provided with the adjusting rod that can regulate the flexible pipe height between pole 6 and storage tank 1 inwall, adjusting rod is made up of positive screw mandrel 15, anti-screw mandrel 9, silk tube 8 and locking nut, and wherein positive screw mandrel 15 1 ends are installed on the pole 6, and the other end screws in silk tube 8; One end of anti-screw mandrel 9 is installed on storage tank 1 inwall, and the other end screws in silk tube 8; On positive screw mandrel 15 and anti-screw mandrel 9, all be combined with locking nut.
When people separate urine, generally do not need a lot of water just can rinse, therefore can pull knob 2 skin plug 5 is opened, the upper port place that the interior water of storage tank this moment is put into arm gets final product.When people defecate, water base in the storage tank need have been put just can rinse, can move knob 3 this moment 17 unlatchings of skin plug are got final product.
