CN2150256Y - Sealed-type flushing device for toilet - Google Patents

Abstract

The utility model relates to a sealed-type flushing device for a toilet, which is composed of a water inlet pipe, a ball-shaped current-limiting valve, a handle, a water storage pipe, a lifting rope, a piston and a water outlet pipe. The sealed-type flushing device for a toilet is characterized in that the lower part of the ball-shaped current-limiting valve is provided with the lifting rope for connecting the piston; when the current-limiting valve rotates 90 DEG, the lifting rope can hang the piston off a water outlet. Thus, water in the water storage pipe flushes to the basin of the toilet. When the water in the water storage pipe is drained, the piston can automatically plug the water outlet, and then the water storage pipe can store water again. The utility model has the advantages of simple structure, low cost, small volume, water saving, etc. The sealed-type flushing device for a toilet is especially suitable for the toilets of families.

Description

Sealed-type flushing device for toilet

The utility model relates to a kind of cleaning device, particularly a kind of lavatory flushing utensil.

Known lavatory flushing device is made up of piston, outlet pipe, connecting rod and the overflow pipe of storage tank, water inlet pipe, float-ball type Water stop valve, band stay cord.After water enters water tank from water inlet pipe, when the water level in the case rises to certain height, utilize buoyancy of water, the float-ball type Water stop valve just can stop up water inlet pipe, water level continues to raise in the case to stop, and when needing the flushing water closet pan, manages pulling or pulling connecting rod, utilize stay cord that piston is sling, the water in the case just can waltz through outlet pipe and rush in water closet pan.But the float-ball type Water stop valve of this toilet flusher, very easily break down and malfunctioning, often can't stop effectively and flow to the water of storage tank, in order to prevent the water in the storage tank, overflow around case lid, an ad hoc level height is lower than the overflow pipe of case lid in case, in case Water stop valve is malfunctioning, unnecessary water just can overflow from the delivery port of overflow pipe.Because water is when overflow pipe overflows, administrative staff are difficult for finding, thereby have caused the waste of water.

The purpose of this utility model is to provide a kind of sealed lavatory flushing device, and this toilet flusher does not have malfunctioning overflow problem without the float-ball type Water stop valve, can avoid the waste of water.

Technology contents of the present utility model (containing embodiment) is as follows: a kind of sealed lavatory flushing device, form by water inlet pipe (1), ball shape flow limit valve (2), standpipe (3) and outlet pipe (4).On the ball shape flow limit valve (2), there is one to go up logical water inlet pipe (1), the narrow waterway (5) of following logical standpipe (3), one side of ball shape flow limit valve (2) has one can make ball shape flow limit valve (2) make the handle (6) that 90 degree rotate, ball shape flow limit valve (2) is installed in the housing (8) of tool spherical hollow space (7), tap into water pipe (1) on the housing (8), under connect standpipe (3), when waterway (5) is aimed at water inlet pipe (1), water in the water inlet pipe (1), can enter standpipe (3) by waterway (5), but because waterway (5) is narrow, therefore this process is slowly, ball shape flow limit valve (2) can rotate in the spherical hollow space (7) of housing (8), and utilize each rubber washer (9) up and down, the water that stops water inlet pipe (1), flow directly into standpipe (3) by the slit between ball shape flow limit valve (2) and the spherical hollow space (7), in the lower end of standpipe (3) delivery port (10) is arranged, lower end one side in standpipe (3), the piston seat (12) that a tool right angle type decompression plate (11) is arranged, piston (13) is hollow, the one end is worn with axle and piston seat (12) and is connected together, making piston (13) is the center with the axle on the piston seat (12), can move up and down, piston (13) is in the time spent of doing that does not have external force, just in time clog delivery port (10), the other end of piston (13) is connecting an end of a corrosion resistant lifting rope (14), the other end of lifting rope (14), the aperture that passes on the right angle type decompression plate (11) is connected with the line hole (15) of ball shape flow limit valve (2) bottom, when handle (6) upwards rotates 90 when spending with ball shape flow limit valve (2), lifting rope (14) is pulled away from delivery port (10) with upwards rotating of ball shape flow limit valve (2) with piston (13) and packs in the right angle type decompression plate (11), in the top of standpipe (a 3) side a small-sized ball float mechanism is arranged, this mechanism is by ball seat (16), spheroid (17) and ball handle (18) constitute, relevant position in housing (8), an airway (19) that leads to atmosphere is arranged, spheroid (17) is connected with an end of ball handle (18), the other end of ball handle (18), link together by axle and ball seat (16), spheroid (17) is the center with the axle, can move up and down by ball handle (18), when moving upward, spheroid (17) is just in time aimed at airway (19), and airway (19) can be sealed.

Operating principle of the present utility model and using method are as follows: under normal situation, the outlet up and down of the waterway (5) of ball shape flow limit valve (2), aim at water inlet pipe (1) and standpipe (3) respectively, one end of lifting rope (14) is in bottom one side of ball shape flow limit valve (2), at this moment, piston (13) is owing to the effect of power is fallen down, and just in time clog delivery port (10), like this, from the next water of water inlet pipe (1), by the narrow waterway (5) of ball shape flow limit valve (2), flow to standpipe (3) lentamente, when the water level in the standpipe (3) raises gradually, the air in the standpipe (3), outside airway (19) discharge pipe by housing (8) bottom one side, when the pipe middle water level was raised to small-sized ball float mechanism, spheroid (17) under the buoyancy of water effect, progressively rose in pipe, and airway (19) sealing the most at last, excessive to prevent the water in the standpipe (3).When the water closet pan water, rotatable handles (6) 90 degree, at this moment because ball shape flow limit valve (2) also rotates 90 degree with handle (6), waterway (5) leaves water inlet pipe (1), lifting rope (14) simultaneously rises to top with ball shape flow limit valve (2) from the bottom, thereby piston (13) is sling and is packed in the right angle type decompression plate (11), because piston (13) hangs delivery port (10), water in the standpipe (3) just rushes at water closet pan from delivery port (10) through outlet pipe (4).The purpose of turning handle (6), piston (13) is to sling, piston (13) is once slinging, handle (6) should rotate back on the original position immediately, allow the waterway (5) of spherical flow-limiting valve (2) aim at water inlet pipe (1) again, one allows the water in the water inlet pipe (1) replenish to standpipe (3), two loosen lifting rope (14), but, because water buoyancy function, add stopping of right angle type decompression plate (11), although at this moment the upper end of lifting rope (14) resets along with ball shape flow limit valve (2) and moves down, when the water level in standpipe (3) still is higher than right angle type decompression plate (11), piston (13) will continue to float in the water and can not seal delivery port (10), have only after the water level in the standpipe (3) is lower than right angle type decompression plate (11), piston (13) has lost the support of water buoyancy, under the effect of power, just automatically leave behind, delivery port is sealed, aspect ball float mechanism, at the initial stage of drawdown in standpipe (3), spheroid (17) is owing to lose the support of buoyancy in the pipe, and fall from airway (19), make unlikely formation blank pipe in the standpipe (3) and influence the speed of bath.

Advantage of the present utility model is:

1, there is not shutoff valve malfunctioning and cause the problem of spilling water waste;

2, simple in structure, cost is low;

3, volume is little, water is economized, impulse force is big.
