Background technique

The utility model relates to water-saving closet applied technical fields, it is almost different from traditional toilet bowl structure, relate generally to me before in China: Publication No. CN 102864830A was announced on January 9th, 2013, with Publication No. CN102720256A, in the two domestic patent applications that on October 10th, 2012 announces, the present invention is the improvement to the closet applied before me, announced.

In toilet where existing closet, it usually can all place the wastepaper basket of a plastic material, a polybag usually can be also covered on wastepaper basket, the use of polybag, there is pollution certainly to environment, and, plastic paper basket is certain to messy after a period of time, since wastepaper basket is usually not fixed, compare light, and special use environment, the dirty inconvenient cleaning of wastepaper basket, and wastepaper basket is plastic material, so wastepaper basket service life is shorter, the wastepaper basket service life especially between public places sanitary is shorter, so service life shorter plastic material wastepaper basket is unfavorable for toilet and keeps preferable hygienic conditions, toilet wastepaper basket higher operating costs simultaneously.

Hand basin is usually also had in existing toilet.

The above two tank for excrement pan of my application, can be small than conventional water tank, but also to occupy certain space certainly, while water tank can be separated with closet body.

Summary of the invention

Tank for excrement pan of the present invention mainly reduces the component part of some tank for excrement pan, and structure is very simple.

Tank for excrement pan mainly includes the valve on seal-off pressure cylinder barrel (54), piston (55), pitch brace (56), cylinder barrel water-in and water-out pipeline and pipeline, there are the first water inlet line (52.), the second water inlet line (50), outlet conduit (40) outside the seal-off pressure cylinder barrel (54) of piston cylinder (55) and cylinder barrel wall composition, pitch brace is connected with piston, across cylinder barrel one end, have on second water inlet line valve (461), also there are valve (46) on outlet conduit.

Two water inlet line of closet, it is connected with closet seal-off pressure cylinder barrel (54), two pipelines are located at piston cylinder two sides, wherein the first water inlet line (52) is also cylinder barrel outlet conduit, the first water inlet line Inlet and outlet water function alternate application simultaneously.

First water inlet line is communicated with pressure water inlet major trunk roads (53), and the second water inlet line is connected to by first pressure control valve (461) with major trunk roads (53).First, second water inlet line is connection, and tank for excrement pan piston cylinder two sides cavity and the first, second water inlet line, the valve (461) in pipeline (50) are a linkers when opening.

In cylinder barrel inner piston two sides, since wherein piston side is connected with pull rod (21) and pull rod passes through water tank, so when cylinder barrel inner piston is by water pressure, the pressure area for having pressure piston to have pull rod side by water does not have pull rod side by the pressure of water with piston Power area is compared, the circular section area of the pitch brace across water tank is just lacked, when water tank the second water inlet line valve (461) is opened, two water inlet lines have identical high pressure water flow, if water tank piston not in piston side water tank bottom lesser by pressure, that is, when pitch brace is not pierced by water tank completely, it is mobile that water flow just will push piston, so that pull rod is pierced by water tank completely, then piston rest, is located at one side bottom of cylinder barrel.The pull rod of water tank of the present invention has the function of controlling the movement of water tank piston.

Water tank of the present invention, does not need bracing wire, and the pull rod for stretching out water tank is not acted on by spring, and water tank does not go out the pipeline of water flow to water tank outlet, and water tank overall structure is simple, compared with most water tank, it is convenient to omit multinomial component element.

There is flow valve on water tank water intake pipeline (50), can control flows per unit time when tank for excrement pan adds water, realize when being no more than water tank maximum amount of water, facilitates the time to realize waters different to water tank addition for different.

The pressure valve of closet GRAVITY CONTROL of the present invention reduces bracing wire, the outer conducting tube of gravity, and structure is simple, and pressure needed for valve is much smaller in control pressure ratio background technique scheme needed for control valve.

The opening pressure valve A of two GRAVITY CONTROLs of closet of the present invention, pressure valve B is closed, is open and close state valve opposite always when being mounted on closet.

Two pressure valves of the GRAVITY CONTROL of squatting pan, it is following to be separately mounted to closet basin two sides foot position, people is at one's leisure, bipod can directly or indirectly step on two valve gravity conductive plates, to be opened by GRAVITY CONTROL pressure valve, it closes, valve respectively includes closet gravity conductive plate (42, 421), connecting rod (43, 431), spring (44, 441), inlet and outlet pipe lines, valve plug (45, 451), valve cavity (46, 461), two valve plugs are located in its cavity, valve plug central upper portion is connect with connecting rod, connecting rod passes through valve cavity upper wall, connecting rod top is connect with conductive plate, there is spring pocket on connecting rod between conductive plate and cavity upper wall, valve plug has and cavity inner wall angle, shape, the same outer surface of structure is corresponding with cavity inner wall surface, valve plug is by spring force or human body weight Under power effect, valve plug surface corresponding with cavity can be covered, plugging valve water inlet line or outlet conduit or cover valve realization closing when blocking water-in and water-out pipeline simultaneously；When valve plug is far from cavity inner wall, valve, which is realized, to be opened.Valve

Pressure valve whole water-in and water-out pipeline or whole water inlet lines or whole outlet conduits can be covered and be blocked by valve valve plug simultaneously with valve cavity connecting tube road junction, realize that valve is closed, it is on the contrary, pressure valve whole water-in and water-out pipeline or whole water inlet lines or whole outlet conduits can not covered and be blocked by valve valve plug simultaneously with valve cavity connecting tube road junction, realize that valve is opened.Pressure valve whole water-in and water-out pipeline or whole water inlet line or whole outlet conduits and valve cavity connecting tube road junction position are located within the scope of valve valve plug can cover and block, the water-in and water-out pipeline of valve can be one respectively, if it is one or more, so every group of water-in and water-out pipeline will be evenly distributed on around valve plug and cavity, make valve plug in the process that moves up and down the uniform water-in and water-out pressure by around.

Valve plug and covered with it and the two sides of valve cavity inner wall that block can be frustum cone side structure, each valve plug side with The angle of its axis, it is identical as valve cavity inner wall side and inner wall axis angle, so valve plug and valve cavity inner wall are salable under pressure tight, the more press the more tight.Valve plug and cavity inner wall structure can also be cylindrical body, ellipsoid, triangle body, polygonal body or other irregular body structures, valve plug can also be both ends ring installation or O shape cushion rubber, intermediate slightly thin structure and cavity cooperate, as long as valve plug can move up and down under the drive that the connecting rod being attached thereto moves up and down, realize the inlet and outlet pipe lines of valve plug covering and plugging valve cavity inner wall and the circulation of opening valve inlet and outlet pipe lines, so that it may realize control of the human bady gravitational to closet valve.

Two pressure valve valve plug upper and lower surfaces of GRAVITY CONTROL have through-hole (47,471), and when number of openings is more than one, all through-holes are evenly distributed on valve plug axis.During valve plug moves up and down, especially start the moment moved down in valve (461) valve plug (451), through-hole can make valve plug, and water flow easily circulates up and down, greatly reduces the mobile resistance of valve plug.

It is realizing except the range between the valve plug and corresponding cavity inner wall that valve inlet and outlet pipe lines are covered and blocked, certain gap or groove, recess can be set, and cancel the through-hole on valve plug, when valve plug and inner wall covering, being adjacent to, the water above and below valve plug can be circulated by gap or groove.

Valve cavity bottom has axle sleeve (49,491), and a bit of shaft (48,481) are arranged at valve plug lower part, and shaft lower end is located in axle sleeve, and shaft axis and valve plug axis are in same straight line or parallel.

Shaft is together with the connecting rod on valve plug, increase valve plug can be played to move up and down, reach concentricity when upper and lower rearmost position, simultaneously, the presence of shaft, piston bottom can be made to be reduced area identical with shaft cross-sectional area by water pressure area, when valve has pressure flow, valve plug can be reduced in the intracorporal shaft direction of valve cavity, that is the area of the suffered hydraulic pressure in valve plug bottom, it is exactly that valve plug can reduce suffered water pressure upwards, valve shaft, it can reduce valve pressure conductive plate, connecting rod active force applied to valve and have the function that control valve plug and move down, compared with pressure valve does not have shaft, lesser pressure can be passed through, it plays similarly to the effect of pressure valve control, closet is used if it is the lesser child of weight, the control to closet pressure valve can also be realized very well.

The double force control valve door of closet, it is controlled without bracing wire, structure is simple, moreover, because closet of the present invention is super water-saving, valve inlet and outlet pipe lines and the pipeline opening internal diameter on valve can easily be controlled within 5 millimeters, valve plug maximum gauge is can be controlled within 12 millimeters, valve cavity inner height is can be controlled within 20 millimeters, so two valves are not only simple in structure, and small and exquisite.

There are also flushing pressure control valve C on tank for excrement pan outlet conduit, valve includes valve cavity (39), third valve plug (36), water inlet line (29, 30, 31), second outlet conduit (2), connecting rod (34), cross bar (32), spring (35), bracket (33), there are two symmetric inlet pipelines (29 on the outside of valve, 30), one water inlet line (31) are arranged at top, there are also two symmetrical outlet conduits (2) on the outside of valve, outer pipeline opening of two groups of inlet and outlet pipe lines on valve cavity of valve is in same level, valve leave unused static closing when two groups of pipeline openings by valve plug side while covering and blocking, valve plug central upper portion is connected with connecting rod (34), Connecting rod passes through at the top of valve cavity, connecting rod also extends through at the top of bracket (33) simultaneously, a cross bar (32) are further fixed on connecting rod (34), there is spring (35) to be sleeved on connecting rod between cross bar top and bracket lower part, water inlet line (31) passes through cross bar (32), valve plug (36) further include one horizontal through valve plug axis intake tunnel (37) and one horizontal through valve plug axis exhalant canal (72), two channel (37 on valve plug, 72) it is connected in same level, when valve plug is located at cavity extreme higher position, the connection corresponding with the inlet and outlet pipes road junction on the outside of valve respectively of the passway of two access ways, each group of symmetrical inlet and outlet pipe lines on the outside of valve can only retain one, it is exactly valve outside by two outlet conduits (2) that valve plug covers and blocks, water inlet line (29, 3 0), can be retain one therein, two pipelines of every group go out, water inlet line.Only in this way when water enters valve cavity, valve plug will receive the water pressure of the water inlet covered by valve plug, and it is mobile to be unfavorable for valve plug.Valve plug also passes through the through-hole (38) of valve plug upper and lower surface, and number of openings is greater than for the moment, and through-hole is evenly distributed on valve plug axis, and through-hole cannot cannot intersect with the disengaging aquaporin on valve plug, be connected to.The water that through-hole can play the role of valve plug or more can circulate, and valve can also cancel through-hole, on two surfaces of valve plug and the sliding contact of valve cavity inner wall, gap or groove is arranged, the water energy of valve plug or more is made enough to circulate.

Valve water inlet line (31), just pass perpendicularly through cross bar (32), pipeline (31) is in bracket (33) with inner part, it is axle sleeve structure with the hole passed through on cross bar by it, when valve valve plug, connecting rod, cross bar move up and down together, pipeline (31) can guarantee that valve plug cannot rotate in valve cavity relative to cavity, guarantee inlet and outlet pipes road junction when valve plug reaches highest point on the outside of valve plug Inlet and outlet water channel alignment valve.

Flushing pressure control valve C on tank for excrement pan outlet conduit, the disengaging aquaporin (37 on valve plug can also be cancelled, 72), as long as valve plug can rise enough height under the action of water pressure, it covers valve plug no longer and blocks inlet and outlet pipe lines (29, 2), if eliminating the disengaging aquaporin on valve plug, the structure setting that cross bar (32) pass through pipeline (31) can be cancelled, simultaneously, control valve can also cancel water inlet line (29) simultaneously, water inlet line (30), control valve valve plug wants that enough height spaces can be risen, when valve working and when valve plug is located at cavity extreme higher position, the outer outlet conduit (2) of valve is no longer covered and is blocked by valve plug, water inlet line (31) outlet conduit (2) connection, it is not being covered and is being blocked by valve plug.

Valve A control water tank adds water, and valve B controls water tank hydroblasting closet, and valve C controls the sequence of closet a part bath.

Pass through the water of valve B by tank pipe (40) outflow, it is a part of first by branch's outlet conduit (27), toilet stool washing is carried out rapidly, a part is again through valve C, through by valve outlet conduit (2) after a period of time of setting, realize toilet flushing work, valve C realizes the sequence of control closet a part bath by Time Delay Opening.
