Abstract

The utility model relates to an automatic flushing cistern which comprises a cistern body, a drainage pipe and a drainage valve. The drainage pipe is used for draining water in the cistern body, the drainage valve is mounted at the inner end of the drainage pipe and used for controlling the water in the cistern body to enter the drainage pipe, a working chamber is arranged on the drainage valve and used for enabling the drainage valve to be in the open/close state by the action of the water pressing a valve core when the water flows in and relieving the pressure of the water on the valve core to enable the drainage valve to be in the close state when the water flows out, and a drainage structure used for the water to flow into and flow out of the working chamber is arranged on the drainage valve. The automatic flushing cistern is characterized in that the drainage structure comprises a two-way water pump capable of discharging the water in the working chamber and filling water into the working chamber, and the two-way water pump is provided with two end openings which are communicated with the working chamber and an inner chamber of the cistern body respectively. The two-way water pump arranged on the drainage valve is used for discharging the water in the working chamber and filling water into the same, therefore, the working states of the drainage valve can be controlled by the water pump, and the service life of each functional element in the flushing cistern is prolonged while using performance of the flushing cistern is guaranteed as the two-way water pump cannot move in the cistern body in action processes.

Description

Automatically case falls into water

Technical field

The utility model relates to the bath articles technical field, relates in particular to a kind of case that falls into water automatically.

Background technology

At present; Drowning case in the bath articles on the market adopts siphon principle to make the subsequent use water outflow of deposit in the water tank more; For example application number is 97222169.7 the disclosed a kind of controlled siphon epithelium formula water saving lower water box of Chinese utility model patent; Be equiped with the siphon epithelium formula draining valve that is used to discharge the subsequent use water in the water tank on the casing of this water tank; This siphon epithelium formula draining valve comprises the hollow valve body that sets up on the inner of gutter and gutter on the sidewall that is located in casing, and this hollow valve body constitutes by being located at the underframe that is provided with between the shelly top cover on the end opening in the gutter and top cover and the gutter, and described underframe is provided with and is used for the water inlet that the inner chamber with the inner of gutter and casing is communicated with; And in hollow valve body, be equiped with the middle part and be sealed on the epithelium that the interior end opening of gutter separates with interior end opening and the water inlet on the underframe with gutter; The edge of described epithelium is fixed on the hollow valve body, and can move in the elasticity harmomegathus of axially doing of gutter in the middle part of epithelium, promptly when the epithelium rising; The interior end opening of gutter is communicated with water inlet on the underframe of hollow valve body, so that siphon epithelium formula draining valve is in conducting state; When epithelium was withdrawn, the middle part of epithelium was sealed on the interior end opening of gutter, so that the interior end opening of gutter and the water inlet on the underframe are separated, made siphon epithelium formula draining valve be in the partition state.In addition, on siphon epithelium formula draining valve, be equiped with and be used for drainage tube that the hollow working chamber between top cover and the epithelium is communicated with gutter, wherein; The inner of drainage tube is communicated with hollow working chamber, and the outer end is communicated with gutter, and the middle part of influent stream pipe offers breach; Therefore when water logging there was not drainage tube, water can flow into hollow working chamber through the inner of drainage tube so that epithelium is in retracted mode, and block up through the breach of plugging device with the drainage tube middle part this moment; And the interior outer end that makes drainage tube is when being communicated with; Drainage tube is in the siphon state, discharges thereby the water in the hollow working chamber is introduced gutter, thereby makes the pressure in the hollow working chamber descend; The pressure reduction of the both sides up and down of epithelium increases; So that the water of epithelium downside makes epithelium be in the rising state epithelium jack-up that makes progress, and water can be flowed into discharge pipe and discharged by the water inlet of offering on the underframe this moment.But because after drainage tube does not have in the entry; Plugging device makes before the inside and outside two ends of drainage tube are communicated with, water can be always outer end through drainage tube be introduced into gutter and be discharged from, and this part current because impact force is little; Can not play the effect of flushing; Thereby caused the waste of water, increased the water supply volume of flushing process, and since the outer end of drainage tube need be in casing frequent movement to realize control to the duty of siphon epithelium formula draining valve; Thereby make the outer end of drainage tube damage easily, and when the generation of the outer end of drainage tube is damaged, will cause whole drowning case to leak.

The utility model content

The utility model provides a kind of case that automatically falls into water, be intended to solve the damaged easily problem of drainage tube that the drainage tube frequent movement of prior art decline water tank causes.

The technical scheme of being somebody's turn to do the case that falls into water automatically is following:

Automatically case falls into water; The gutter that comprise casing, is used for the water in the casing is discharged and the inner installing of gutter be used to control the draining valve that water in the casing gets into gutter; Have on the described draining valve and be used for compeling the spool action so that draining valve is in conducting state, when water flows out, separates the compressing that dewaters to spool so that draining valve is in the working chamber of partition state through hydraulic pressure in that current are fashionable; Described draining valve is provided with the flow guiding structure that is used to supply water and flows into working chamber and flow out from working chamber; Described flow guiding structure comprises the two way water pump that the water that is used for discharging in the working chamber again can water filling in working chamber, and described two way water pump has the both ends open that is communicated with the inner chamber of working chamber and casing respectively.

Control connection is useful on the controller of control of pump work on the described water pump.

The described case that falls into water automatically also comprises the inlet control device that is used to control the casing water inlet.

Described inlet control device comprises the water inlet electromagnetic switch valve that is used to control casing; Control connection is useful on the controller that control water inlet electromagnetic switch valve opens and closes on the described water inlet electromagnetic switch valve; Be connected with the liquid level sensor that is used for height of water level in the measuring point casing, also opens and closes through controller control water inlet electromagnetic switch valve on the described controller, described water inlet electromagnetic switch valve passes through controller and water inlet electromagnetic switch valve control connection.

Described inlet control device comprises and being used for through height of water level in the mensuration casing with the float valve of the water inlet of control casing.

The utility model through the two way water pump that is provided with on the draining valve come in discharging working chamber water and to the working chamber water filling; Therefore water pump not only can be realized the control to the draining valve duty; And owing to can't in casing, move in its course of action; Thereby improve the application life of each function element of the case that falls into water, ensured the functional performance of drowning case.
