Abstract

The utility model relates to a siphoning type flushing cistern. The utility model is characterized in that the bottom of the siphoning type flushing cistern is connected with a water outlet tube, the water outlet tube is sheathed with a siphon tube whose top surface is sealed, and the bottom of the siphon tube is provided with a water inlet. The upper opening of the water outlet tube is in horn shape, and the lower opening of the water outlet tube is provided with a throttle orifice. A positioning supporting post is arranged in the radial clearance between the water outlet tube and the siphon tube. The inner part of the cistern body can be provided with a manually controlled operating mechanism which is composed of a floating ball, a draw rod and a water discharging body. The siphoning type flushing cistern uses siphoning method to conducting water for flushing, so the utility model has not abrasion, permanent use and good water-saving effect.

Description

Siphon flushing cistern

The utility model relates to a kind of wc flushing cistern, particularly a kind of hydrocone type wc flushing cistern.

The existing wc flushing cistern that is used for lavatory, lavatory etc. roughly pulls the foundary weight formula, inhales the formula that opens, electromagnetic type, light-operated, ball float control type, valve control type or the like automatically, though this class wc flushing cistern respectively has characteristics, but all can not solve the wear problem of delivery port sealed rubber, that is, under the condition of work of flushing that frequently discharges water, the caulking gum that is located at delivery port very easily weares and teares, thereby destroy sealing and cause fault such as leak, so existing all kinds of wc flushing cisterns remain in maintenance rate height, application life shortcoming such as weak point, energy saving difference.

The purpose of this utility model is that a kind of long service life, water-saving result permanent hydrocone type wc flushing cistern good and simple in structure, with low cost will be provided.

The utility model has been broken traditional design circle, with the alternative existing rubber sealing structure of the flow guiding structure of hydrocone type Sealed casing pipe, has fundamentally solved the sealing wear problem.This programme is mainly by casing, outlet pipe and syphon are formed, casing is as storage cistern, its upside is provided with the water inlet interface that is connected with water inlet pipe, the bottom surface of casing has a pore that coincide with diameter of outflow tube, be tightly connected at the bottom of this pore of water outlet caliber and the case, the casing that is positioned at suitable for reading of outlet pipe, outside its end opening is positioned at the bottom of the case, outside the outlet pipe in casing, be with the syphon of end face sealing, siphonal bottom has some water inlets that are communicated with casing with certain altitude, siphonal height and diameter all are slightly larger than outlet pipe, that is all have certain interval between the tube wall of the suitable for reading of siphonal end face and outlet pipe and two pipes.The operating principle of this programme is when casing is filled with water to the water inlet height of syphon bottom, current will be consistent in the gap of siphonal water inlet inflow sleeve pipe and with the casing water level, when water level rise to outlet pipe suitable for reading after, because case is outward still at continuous water-filling, instantaneous vacuum partly be extruded and be produced to clearance air between the outlet pipe mouth of pipe and the syphon sealing end face will, in case, can form syphonic water flow under the compression of hydraulic pressure and flow out from the outlet pipe end opening, this syphonic water flow attack time is longer, flow is big, can satisfy rinsing requirement.After water level in the case is lower than siphonal water inlet height, vacuum breaking, siphon stops automatically.When water level in the case arrive once more outlet pipe suitable for reading after, siphon produces once more, back and forth can produce the syphonic water flow of discontinuity so successively automatically.In order to improve siphon effect, increase the uniformity and the instantaneous inflow of outlet pipe water inlet suitable for reading, outlet pipe suitable for reading can be made tubaeform, end opening outside also can be at the bottom of it is positioned at case is provided with a throttle, with its water yield of relative minimizing, guarantee that in case filled water amount hour also can normally produce syphonic water flow.In above-mentioned design, need only ball float, pull bar that configuration is used always in case and the water discharging body that is connected with pull bar and just can form a manual operating mechanism, in order to wash, reach energy-conservation purpose by the Artificial Control syphonic water flow.Feature of the present utility model is that the bottom surface of casing is connected to outlet pipe, outside the outlet pipe in casing, is with the syphon of end face sealing, and siphonal bottom has water inlet.

The utility model utilizes the air contraction principle, obtain the flushing current by siphon mode, the hermetically-sealed construction of delivery port does not need any as accessories such as rubber, valves, solved the wear problem of wc flushing cistern seal effectively, make water tank can keep permanent developing result and maintenance rate is low, long service life, water saving ability are better, have certain practical value.

Below with reference to embodiment and accompanying drawing the utility model is further described.

Fig. 1, Fig. 2 are structure principle chart of the present utility model;

Fig. 3, Fig. 4 are the schematic diagram that has manual mode operation mechanism;

With reference to Fig. 1, Fig. 2: the utility model comprises casing 1, outlet pipe 2, syphon 3, the casing upside is provided with into water interface 4, there is a pore bottom surface of casing, and outlet pipe is tightly connected with tank floor behind this pore, the casing that is positioned at suitable for reading of outlet pipe, its end opening is positioned at outside the casing, outside the outlet pipe in casing, be with the syphon of end face sealing, this siphonal bottom has some water inlets 5, present embodiment adopts the water inlet of three five equilibriums, is the tripodia shape.Suitable for reading and two pipes of syphon end face and outlet pipe radially all leave certain clearance, wherein the gap length up and down at two pipe tops is by the diameter difference decision of two pipes, generally proportional, the inflow of siphonal water inlet also matches with above-mentioned gap, usually makes water inlet produce the difference gap up and down that highly is slightly larger than two pipes.It is tubaeform that outlet pipe suitable for reading can be made into, and its end opening inwall can be provided with a throttle 6, and outer wall is connected with extension tube attached by screw thread, at outlet pipe and siphonal radial clearance place, can set positioning pillars 7, to improve the stability of outlet pipe, the width of this pillar conforms to the semidiameter of two pipes.Each above-mentioned in the present embodiment parts are welded by plastic welding rod at the bottom of outlet pipe and the case by the plastic compression molding.

With reference to Fig. 3, Fig. 4: set in the casing of present embodiment by ball float 8 commonly used, the manual mode operation mechanism that pull bar 9 and water discharging body 10 constitute, wherein ball float is connected with the water inlet interface, be fixed on the frame of casing, external current flow in the handle of ball float, when water level rises to certain altitude in the case, can close into water automatically, water discharging body can be that cystosepiment is connected with pull bar and swim in that the water surface allows in the case, when needs wash, pull bar makes cystosepiment sinking draining advance syphon as long as leave behind, can produce siphon flushing current, siphon stops after water level in the case is lower than the syphon water inlet, and enters next circulation automatically.
