Description

A kind of province's penstock of water-closet tank

Technical field

The utility model relates to a kind of province's penstock of water-closet tank.

Background technology

Because modern society's population is concentrated toward the urban district, caused the daily water yield in urban district to feel not enough gradually, this is the present common trend in each important city in the world.And in the resident's daily water consumption of city, have 30% to be to be used for the lavatory bath approximately, so if the discharging quantity of water that can save toilet then can be improved the water resource supply predicament of difficulty day by day, the while also can reduce the construction of reservoir indirectly and avoid ecological environment to be destroyed.Traditional type toilet flush capacity is about the 12-16 litre, if do not add the water-saving device, disposablely during use all washes very waste off.

The water-saving mode of tradition water-closet tank mainly is divided into the stepless bath, three kinds of modes of two-part bath and composite type bath.Stepless bath refers to that discharging quantity of water controlled by the time length of pressing pressure handle, when pinning pressure handle and do not put, continue bath, and stop bath when decontroling pressure handle immediately, No. 292654, TaiWan, China patent " the simple and easy province of flush toilet water controller " for example, be that the valve top part that has air chamber in the bottom adds the buoyancy of Yi Disk Ti ， Disk body weight greater than air chamber, therefore when decontroling pressure handle, valve is closed immediately, forms the stepless bath; M249979 number " structure-improved of water-closet tank ball float " of Taiwan patent China then is that the air chamber with the valve bottom tamps, so valve do not have buoyancy fully, and forms the stepless bath; The bath of this stepless, no matter water what, all need press the pressure handle long period, use inconvenience.

Two-part bath be with discharging quantity of water be divided into many, two kinds less, during a small amount of the bath, only go out the part water yield, to reach the water-saving purpose, during a large amount of the bath, then whole water yields are gone out, for example TaiWan, China patent No. 294225 " single-grip multifunctional closestool water economizers " is that a ball float respectively is set on two drag-lines, control what of discharging quantity of water respectively, just do not give and mentioning for the structure of control ball float position; The principal character of TaiWan, China patent No. 454776 " two-part water-saving closet ball float micromatic settings " is that the device of fine-tuning ball float position is a cylindrical shell; TaiWan, China patent No. 474343 " water tank water-saving device " then is to place a ball float on the drag-line in two drag-lines, and with clip control floating ball device, an air access hole is set on the air chamber in addition, and does not give explanation for the structure of clip; What of discharging quantity of water are No. 553249, TaiWan, China patent " the sealing valve block structure improvement of water tank water-saving device " then control respectively by two drag-lines; make valve lose buoyancy the air discharge by access hole during a small amount of the bath; the position that it is characterized by access hole can be adjusted; so that air comparatively fast or is more slowly arranged light; this two-part bath; usually comparatively waste time and energy on changing the outfit, and its part is complicated, price is expensive.

As for the composite type bath, be the characteristics of comprehensive stepless and two-part bath, only go out the part water yield when promptly washing by water on a small quantity, belong to the one-part form bath, the pressure handle long period is then pressed in a large amount of baths, belongs to the stepless bath; This composite type is washed by water, and is therefore easy than the stepless bath as long as let go after pressing pressure handle when washing by water on a small quantity, and a large amount of bath can all be washed water in the water tank off, and toilet rinses can decontrol pressure handle, therefore can the ten minutes water-saving.For example TaiWan, China patent No. 491314 " overturning closet water tank tap structure " (as Fig. 6) can be adjusted the size of air chamber below arc-shaped slot, controlled water flow enters the speed of air chamber, and force the air in the air chamber in pore, comparatively fast or more slowly to be discharged, cause valve early or than slow loss of buoyance to be closed, and reach the purpose of a small amount of when bath water-saving, but when initial the installation, need overturn valve and by air chamber below the size of regulation and control arc-shaped slot, more bothersome; TaiWan, China patent No. 539018 " the Pneumatic-control type toilet is economized the water management structure " (as Fig. 7) is characterized by the through hole that is provided with on the air chamber of valve bottom and can be adjusted to different angles position (α), the air velocity of discharge is controlled in different angles position by through hole, COS (α) value is bigger, valve is closed later, because COS (α) value is also non-linear, so during initial the installation, adjusting angle position (α) needs test repeatedly more bothersome; No. 433306, TaiWan, China patent " water-closet tank collude floating water-saving device " (as Fig. 8) for another me is colluded version institute by a floating block and and is constituted, my TaiWan, China patent M245229 number " the big tail folder water-saving device of water-closet tank " (as Fig. 9) is made of a floating block and a big tail folder, and my TaiWan, China patent M248813 number " the crocodile clip formula water-saving device of water-closet tank " (as Figure 10) be made of a floating block and a crocodile clip, more than three patents be useful for and do not have a valve of air chamber.Further investigate again and test through the inventor, be mainly used in valve with air chamber, in the air chamber bottom one exhaust opening is set highly suitably, when valve is pulled up Hou, only can allow the part air discharge, and the buoyancy that allows remaining air produce is slightly less than the weight of valve in water, therefore valve is pulled up Hou and can't floats, control the position of floating of a floating block in addition with a locator, utilize the buoyancy of floating block can hold the valve that opens, and reach the water-saving purpose of a small amount of bath, wherein adjustment can be given in the position of locator, set what of a small amount of when bath water yield, and since in the air chamber buoyancy that remaining air produces less than the weight of valve in water, so valve weight in water to offset this buoyancy Hou very little, the buoyancy of required relatively floating block can reduce, therefore can reduce the volume of floating block, and reduce cost.

The specific embodiment

As Fig. 1, the utility model is made of a valve 10, a floating block 15 and a locator 20, valve 10 is a rounded valve gap 101, its front side, top is provided with a lug 102, for the socket collar 107, valve 10 top rear are provided with two support arms 103, each support arm is provided with a circular hole 104, hang on the lifting lug 40 of overflow pipe 30 two bottom sides in the water tank for cover, valve gap 101 bottoms are provided with an air chamber 105, its bottom, front side is provided with an exhaust opening 106, it is characterized by the above buoyancy that air produced in exhaust opening 106 tops less than the weight of valve 10 in water; The collar 107 is connected the drag-line that is connected into by a plurality of connection straps 108 and ball 109.

The structure of floating block 15 is mainly a buoyancy aid 151, and the proportion of its material is less than 1, and the central authorities of buoyancy aid 151 are provided with a valve opening 152, and the diameter of valve opening 152 can pass through for ball 109 and connection strap 108 greater than ball 109.

Locator 20 be configured to a flat board 201, be provided with a finedraw 202 in the middle of the one side, finedraw 202 tail ends then are expanded into a small sircle hole 203, the opposite side of small sircle hole 203 positions deflection dull and stereotyped 201, these finedraw 202 width are suitable with connection strap 108, can pass for connection strap 108, finedraw 202 arrival ends are horn-like, and connection strap 108 is passed; Small sircle hole 203 diameters can stop that less than ball 109 diameters ball 109 passes through; Dull and stereotyped 201 opposite side both sides respectively are provided with one and pinch plate 204, can pinch with two fingers for setter, conveniently advance or step back locator 20.

As Fig. 2, locator 20 is positioned at the appropriate location on the

connection strap

108, and 15 of floating blocks withstand on locator 20 belows, and valve 10 is because water pressure then is closed condition.As Fig. 3, when a small amount of bath is desired in the urine back, let go after then pressing pressure handle, because pressure handle has affected the drag-line that is connected into by a plurality of connection straps 108 and ball 109 and pull-up valve 10, this moment valve 10 bottom sides air chamber 105, be immersed in the water and no longer communicated with air, and after the discharge of the air more than exhaust opening 106 tops, the air more than remaining exhaust opening 106 tops in air chamber 105 only, because the buoyancy that remaining air produced is less than the weight of valve 10 in water, so valve 10 former should sinking and recover closed condition, but buoyancy because of floating block 15, valve 10 still is opening, and current continue bath, and water level descends gradually in the water tank.As Fig. 4, when water level is lower than floating block 15, floating block 15 loss of buoyance, so valve 10 closes, current no longer flow out, and reach the water-saving purpose of the discharge section water yield.

In addition, by Fig. 3, Fig. 4 and above-mentioned bath state as can be known, need only the height that changes locator 20 position on connection strap 108, when drawdown, can make floating block 15 morning or slow loss of buoyance, thereby change discharging quantity of water, promptly high more when floating block 15 positions, discharging quantity of water is few more, otherwise, the position is low more, and discharging quantity of water is many more.As for the height that changes locator 20 position on connection strap 108, its method is as long as pinch plate 204 with two fingers, pull back and to withdraw from locator 20 from connection strap 108, and then in predetermined connection strap 108 positions locator 20 is pushed ahead by finedraw 202 arrival ends, promptly finish the location.

As Fig. 5, when a large amount of bath, then continue to pin pressure handle and do not put, pressure handle affected the drag-line pull-up and held valve 10 this moment, and current begin bath, and ordinary water level is reduced to floating block 15 when following, because of valve 10 is still held by drag-line, so current continue to go out, and are rinsed in the user sees toilet, then decontrol pressure handle at any time, valve 10 is closed, bath stops, and the water yield is directly proportional with the time length of pinning pressure handle when promptly washing by water in a large number, long more discharging quantity of water remaining sum of time many (belonging to the stepless bath).By Fig. 5 also as can be known, in a large amount of water-rinsing processes, floating block 15 will reduce and descend along with water level, cause floating block 15 to be away from the below of locator 20, this moment, locator 20 was pinched plate 204 1 sides because be partial to the position of small sircle hole 203, was central point with small sircle hole 203 therefore, the finedraw 202 of the center of gravity deflection opposite side of locator 20, thereby locator 20 is towards finedraw 202 lopsidedness, so locator 20 can not drop in a large amount of water-rinsing processes.
