Description

A kind of portable toilet with flushing valve

Technical field

The utility model relates to a kind of portable toilet, specifically refers to a kind of portable toilet with flushing valve.

Background technology

Portable toilet is because it is easy to use, especially is suitable for special population such as old man, children, patient or traveller and liked deeply.But portable toilet is because need frequent shift position, so can not fixedly connected with the water source.Common portable toilet is outwelled the dirt in the staving earlier usually, and then adds water to the interior flushing of staving, and then sewage is outwelled.But so just there is a problem, when the dirt in the portable toilet also remains in the toilet, when the user uses toilet, because have only a staving, so very unhygienic when using.For this reason, people have developed a kind of portable toilet that volleyball association's dirt and staving are separated.This class portable toilet is divided into two parts, a part is similar to common toilet, comprise the staving, cushion, the bung that make things convenient for usefulness, people are identical with common fixed toilet to the use of this toilet at one's leisure, and different is that described staving also is provided with a water storage box that is used to wash staving outward; Another part is a dirt box, and it places the below of staving, and the dirt in the staving of the convenient back of people enters dirt box after the flushing that discharges water, topple over after dirt in the dirt box is full again.The use of the split type toilet of this class promptly conveniently has health, liked by the customer.The thing followed is that the flush valve that conventional toilet is used obviously is uncurrent in the split type portable toilet of this class.The patent No. is that the PCT application of WO9606233 discloses a kind of flushing valve that uses at this class split portable toilet specially.It comprises staving, places the water tank of staving periphery, forms the airtight cavity that holds clear water between described water tank and the staving, and the upper surface of water tank is provided with one and runs through the water tank end face and go deep into the interior water pump of water tank; One end of water pipe connects water pump, and the other end connects the bath mouth via flushing valve; Described flushing valve comprises valve seat, spool, offers the through hole that water supply stream passes through on the described valve seat, and this through hole is passed at the rear portion of spool movably, and spring housing is connected on the front end of spool.During flushing, press water pump, the water in the water tank impacts spool under the pressure of water pump, the spool extrusion spring, and length of spring compressed, passage is exposed in the spool reach, and current enter staving; Flushing finishes, and unclamps water pump, and spool is returned to the position of closed channel under the spring force effect.This flushing valve is owing to used this metalloid spare of spring, and of long duration on the one hand, the elastic force of spring can relax, and influences the accuracy of valve open and close, and on the other hand, spring use for a long time can be corroded.

Summary of the invention

Technical problem to be solved in the utility model is the situation at prior art, provides a kind of flushing valve opening and closing more flexible, accurate, and the portable toilet with flushing valve that can not be corroded.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this has the portable toilet of flushing valve, comprise water tank, staving and flushing mechanism, described water tank places the periphery of staving, and form the airtight cavity of splendid attire clear water with staving, described flushing mechanism comprises being installed in tank upper cover and running through loam cake and stretches into water pump in the water tank, place water pipe and flushing valve in the water tank, described water pipe one end connects the delivery port of water pump, the other end connects the water inlet end of flushing valve, described flushing valve comprises valve and water nozzle, water nozzle passes barrel body wall and exposes at the staving inside front, it is characterized in that: described valve comprises the valve frame of a hollow and is fixed on the interior elastic material seal of this valve frame, the water inlet end of valve frame promptly links to each other with described water pipe as the water inlet end of flushing valve, the water side of valve frame and described water nozzle water inlet end are sealedly and fixedly connected, and this water nozzle water inlet end is the water side of flushing valve.The seal of selected elastic material utilizes the material characteristics of part itself, replaces spring, makes the opening and closing of flushing valve more flexible, accurate, and has avoided the etching problem that metal spring brought.

For the ease of processing and assembling, described valve frame can comprise a hollow housing, and its inner surface front portion has one to projecting inward flange, is fixed with one on the sidewall of inner surface and holds up frame; Described seal comprises a seal head and fixing head, and seal head is connected by connection strap with fixing head; Described seal head is kept out on the flange of housing, and described connection strap passes holds up frame, keeps out at the other end of holding up frame by fixing head and fixes.Described elastic sealing element is in when water inlet, seal under the effect of the impact of current and hydraulic pressure, elastic elongation, seal head separates with flange, current enter; After bath finished, seal head restored to the original state under the effect of elastic force again, valve closing.

Preferably, described housing can adopt cylindrical, and described flange is taper, and the described frame of holding up comprises that one is fixed on the flank on the inner walls and the cylinder of the hollow of fixedlying connected with flank; Described seal head be shaped as the taper shape suitable with flange, being shaped as of connection strap is cylindrical, fixing head be shaped as taper shape; Like this sealing between seal and the valve frame with separate just more convenient and flexible.

For the convenience of installing, described cylindrical cross section can be " C " font, and like this, when mounted, connection strap can assemble very convenient from cylindrical opening part plug.

Compared with prior art, the utility model has utilized the resilient characteristic of elastic material seal itself, and the good features of shape of fitted seal performance between the taper, this flushing valve is used for portable toilet, the opening and closing of flushing valve are all very flexible, and avoided using corrosion that metalwork brought such as spring and phenomenon such as lax.
