Embodiment
Further details of elaboration is done to the technical solution of the utility model with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1：As shown in Figures 1 to 4, a kind of water-saving vacuum toilet, including toilet seat 1, be arranged in toilet seat 1
The toilet tanks 2 in portion and the closestool case 3 for being arranged on the side of toilet seat 1, are provided with vacuum drain valve 4 and use in the closestool case 3
The controlling switch 5 of switching, sewage draining exit 5 is provided with the bottom of toilet tanks 2 between the outlet of control vacuum drain valve 4 and entrance,
The entrance 411 of vacuum drain valve 4 is connected with the sewage draining exit 5 of toilet tanks, the outlet 412 of vacuum drain valve and the suction of vacuum handling pump
Dirty pipeline（Not shown in figure）It is connected, the outlet pipe 6 of a whole circle is circumferentially provided with along the notch of the toilet tanks 2, along described
The notch of toilet tanks 2 is circumferentially provided with multiple apopores 7 in the bottom of outlet pipe 6, and the whole side for irising out water pipe 6 connects with water inlet pipe 8
Connect.Vacuum drain valve uses Publication No. CN101349070A, and publication date discloses for the Chinese invention patent on January 21st, 2009
A kind of vacuum drain valve.When carrying out blowdown, flushing water is controlled from water inlet pipe is flowed into outlet pipe, then by blowing water pipe bottom
On multiple apopores be drained into toilet tanks and be rinsed, control flushing water to stop rinsing after the completion of flushing, then pass through control
Connected state is between the outlet of switch control vacuum drain valve and entrance, using vacuum handling pump by the dirt in toilet tanks
Outlet through sewage draining exit, the entrance of vacuum drain valve and vacuum drain valve is pumped into soil pick-up pipeline, is finally opened again by control
Close and be off between the outlet of control vacuum drain valve and entrance, complete a blowdown process.The present embodiment is changed
The structure of hydroblasting is carried out in traditional vacuum closestool using nozzle, along closestool notch circumferentially annular outlet pipe, using going out
Multiple small water holes of blowing on water pipe bottom are rinsed, and are extracted the dirt in toilet tanks out in conjunction with vacuum handling pump, so as to enter
One step reduces water consumption, saves use cost.
As shown in Figure 1, Figure 2, shown in Fig. 5 and Fig. 6, the notch of toilet tanks 2 is inner bead shape, i.e. the longitudinal section of the notch of toilet tanks 2 is
Inverted U, including positioned at the toilet tanks notch 1 close to the side of water inlet pipe 6 and the toilet tanks groove for being located remotely from the side of water inlet pipe 6
Mouth 2 212, whole water pipe 6 of irising out is arranged in the inner chamber of inverted U longitudinal section toilet tanks notch；In the present embodiment, toilet tanks groove
The girth of mouth one constitutes about 1/4 or so of toilet tanks notch overall circumference, and the girth of toilet tanks notch two constitutes about toilet tanks notch
3/4 or so of overall circumference.
Outlet pipe 6 and water inlet pipe 8 can use rubber tube, and the flexible pipe such as plastic tube, the inverted U of toilet tanks notch 1 is opened
The distance between two sides L1 is more than or equal at the inverted U inner bottom part of the toilet tanks notch 1 between two sides at mouthful
Apart from L2, outlet pipe 8 in the inner chamber of toilet tanks notch 1 with the inverted U inner bottom part of toilet tanks notch 1
Gap is left between two sides, one end of water inlet pipe 8 is connected with the outlet pipe 6 in the inner chamber of toilet tanks notch 1,
Supported hole 9 is provided with one side of toilet tanks notch 1, the other end of water inlet pipe 8 passes through the side of toilet tanks notch one

Inverted U inner bottom part at the distance between two sides L4, outlet pipe 8 in the inner chamber of toilet tanks notch 2 212 it is outer straight
Footpath is more than the distance between two sides L3 at the inverted U opening of toilet tanks notch 2 212.
From the foregoing it can be that the longitudinal section of toilet tanks notch 1 is an opening and inner chamber larger inverted U,
Therefore it is first by water inlet pipe 8 from the side of toilet tanks notch one when being again installed to water inlet pipe and outlet pipe in toilet tanks notch
The supported hole 9 on side is passed through, then by inverted U opening of the outlet pipe 6 at toilet tanks notch two by toilet tanks notch 1
In the inner chamber for being tucked into toilet tanks notch 1, using supported hole 9 to water inlet pipe 8 and at toilet tanks notch 1
What outlet pipe 6 was supported so that the outlet pipe 6 at toilet tanks notch 1 will not falling from toilet tanks notch 1
Dropped at U-shaped opening；The longitudinal section of toilet tanks notch 2 212 is that an opening is small, the big inverted U in inner chamber, therefore when installing, position
Outlet pipe 6 at toilet tanks notch two is to snap onto toilet tanks notch two at the inverted U opening by toilet tanks notch 2 212
In 212 inner chamber, after being caught in, because the overall diameter of outlet pipe 6 is larger, therefore will not be from the inverted U of toilet tanks notch 2 212
Dropped out at opening.Pass through said structure design so that the present embodiment can be pointed to the water inlet pipe at toilet tanks notch and go out
Water pipe is conveniently installed.In addition, by the longitudinal section of toilet tanks notch one be arranged to one opening and inner chamber it is larger
Inverted U and by the inverted U inner bottom part of the outlet pipe in the inner chamber of toilet tanks notch one and toilet tanks notch one two
Gap is left between side so that hand can be directly protruding into toilet tanks groove by the present embodiment when dismantling water inlet pipe and outlet pipe
In the inner chamber of mouth one, directly water inlet pipe and outlet pipe are pulled, easily dismantled.
