Abstract

The utility model relates to a novel toilet flushing device which is suitable for a toilet and a squatting type closet, which is composed of a sealed air chamber 1 used for storing water and a water feeding and discharging device which is arranged at the lower part of the air chamber and controlled by pressure lever 17 and a interlocking bar 16. The air chamber has no water when nobody uses the toilet, water can continuously enter the air chamber once the pressure lever is applied with force; the water storing quantity can be decided according to the using time of the users. The water in the air chamber can be discharged automatically to flush the toilet when people leave. The device has simple structure and low cost, which can thoroughly avoid the waste of water.

Description

Toilet flushing device

The utility model belongs to a kind of urinal flusher in lavatory, is applicable to sitting urinal and crouching formula urinal.

Existing sitting urinal and crouching formula urinal flusher kind are a lot, early for the public known and widely use hand pulling type flusher, batch (-type) flusher arranged.The flusher of this class formation is all in the waste that can cause big water gaging in varying degrees, and maintenance is frequent.Recently, by China's application number is 86209756, and the patent specification that name is called ' feces of toilet automatic flushing device ' discloses a kind of a kind of New-type toilet flusher of being made up of the controlling organization that has water tank, plug and the plug lifting at the mouth of a river down, float-type water level water inlet control valve etc.It brings convenience to the user, has reduced the waste of water.But the flusher of this structure, and though still exist urine or greatly after an action of the bowels water what, all want the disposable defective that the water tank water has been put.During unmanned at ordinary times in addition the use, water is arranged always in the water tank, advancing, when outfall is not tight, also running water can occurring, cause the waste of water like this.

The utility model purpose is, designs a kind of novel automatic washing device for urinal, change known in the past water tank and advance, discharge structure, when unmanned the use, water not in the case is along with the length of service time changes inflow, reach water as required, the phenomenon of the water of thoroughly putting and ending to waste.And simple in structure, cost is low.

The urinal flusher comprises a closed type air chamber (1) that is used for water, and air chamber (1) bottom assembling lever that is stressed (17) and gangbar (16) are controlled advances, drainage mechanism.

Water intake mechanism by one with intake chamber (2), compression spring (3), the sealing mat (4) of water inlet pipe mouth (9) UNICOM and be connected compression spring (3) and the spring strut (6) of pressure lever (17) is formed.Be closed above the intake chamber (2) with air chamber (1) and isolate, there is a water inlet with air chamber (1) UNICOM the bottom surface

Drainage mechanism is made up of with the valve rod (12) that is connected valve head (10) and gangbar (16) A end valve head (10).

The C end of the pressure lever of sitting type closet (17) joins with gangbar (16) B end, and medium position has an axle center hole (18), is assemblied in by movable axis in the axis hole (19) on bedpan rear side edge, and the D end links to each other with foot rest connecting rod (20); The pressure lever of Crouching type bed-pan (17) extends on the foot position by being installed in ground fulcrum (23), can move up and down with foot-operated active force.

The utility model is compared with prior art, and its obvious advantage is a water not at ordinary times in the air chamber (1), when having only use, water successively, and can according to length decision service time water what, the waste of fundamentally having stopped water.Simple in structure in addition, to make easily and keep in repair, cost is low, and is easy to use, and a very important person just leaves and can wash automatically.Because air chamber is airtight, and room air is compressed behind the water-filling, produce certain pressure simultaneously, the impact force in the time of strengthening draining makes ight soil be able to effective flushing, reaches tangible hygiene effect.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 be the urinal flusher air chamber and advance, the drainage mechanism schematic diagram.

Fig. 2 is a sitting type closet flusher assembling schematic diagram, also is one of the utility model embodiment.

Fig. 3 is a Crouching type bed-pan flusher assembling schematic diagram, also is one of the utility model embodiment.

Fig. 1 hollow gas chamber (1) top is a dome head, it is with dismountable plug sealing that intake chamber (2) is gone up front cover, the compression spring (3) of interior dress, the upper end is fixed on the end face of intake chamber (2), the lower end is connected with sealing mat (4), when unmanned the use, be pressed on the water inlet (5) on intake chamber (2) bottom surface, block water and do not enter air chamber.Following of sealing mat (4) connects spring strut (6), passes water inlet (5), sealing mat (7), has an end socket (8) of mouth, is connected with pressure lever (17).

Gangbar (16) A end is nested together mutually with movable axis (13) on the valve rod (12), the middle part fits together by axle center hole (15) and the FE Tiler (14) that is assemblied on the sewer pipe, and gangbar (16) B end is connected with pressure lever (17) C end with removable pin.

Fig. 2 is a sitting type closet flusher assembling schematic diagram.Air chamber (1) face of binding is a ball shape, advance, on drainage control mechanism is contained in air chamber (1) lower bottom cover, when people need defecate, as long as be sitting on the bedpan seat (22), will make pressure lever (17) D hold stressed decline, the C end moves up owing to leverage, promote to move on the connected spring strut (6), compressed compression spring (3), water inlet (5) is opened, and land and water is continued enter in the air chamber (1).When water inlet was opened, pressure lever (17) also drove simultaneously on gangbar (16) the B end and moves, because leverage moves down gangbar (16) A end, affected valve rod (12) that valve head (10) is descended, and closed outfall (11).Leave seat after an action of the bowels the people, pressure lever (17) D holds stressed releasing, under compression spring (3) elastic force effect, make pressure lever (17), gangbar (16) resets into the state before stressed, and at this moment water inlet (5) is closed, and dewatering outlet (11) are opened and reached the purpose of flushing.Equally, when people urinate,, reach same flushing purpose as long as the foot rest that tramps with one's feet (21) by foot-operated link rod (20) pulling, makes pressure lever (17) be subjected to above-mentioned same active force.

Fig. 3 is a Crouching type bed-pan flusher assembly drawing, air chamber (1) is the sphere tubular structure that binds, the water inlet controlling organization is assemblied in air chamber (1) lower sides position, drainage mechanism is on air chamber (1) bottom surface, pressure lever (17) extends on the foot position by device fulcrum (23) on the ground.When people stool or urine, slam pressure lever (17), with after leave and will produce and the above-mentioned same developing result of basin flusher of sitting.

Each member of the present utility model can be with metal or plastics manufacturing, and its hollow gas chamber and bottom also can be made with pottery.
