Abstract

The utility model discloses a novel flushing device, which includes a spring, a spring seat, an inner core and a pressing cap, wherein the inner core is hollow and adopts a circular conical surface trapezoidal frame at the bottom; an air hole is formed in the side surface of the spring seat; a bulged platform is arranged at the bottom; an air guiding groove is formed in the bulged platform; and the spring, the inner core and the pressing cap are mounted in the base sequentially to form an inner water flow passage and an outer air passage, and the size of the clearance formed between the combined or separated circular conical surface and the bulged platform is adjusted along with the pressure change through the spring, and besides, external air is introduced to the water passage through negative pressure generated by the water flow to form the mixing of water and air, and the purpose of saving water is realized. Through the adoption of the novel flushing device, the water-saving percentage reaches 50% above.

Description

A kind of novel flushometer

Technical field

1, the utility model discloses a kind of water saving fixtures, relates to a kind of novel flushometer.

Background technology

2, the public place generally adopts the time-delay valve switch to flush the toilet greatly after an action of the bowels at present, because this switch discharging quantity of water is big, wastes more serious.It is more big to manage internal pressure simultaneously, and impulse force is more big, and dirt may splash, and is unhygienic.

3, I create a kind of novel aerating flushometer, so the utility model proposes through long-term observation and research.

Summary of the invention

4, at the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, and a kind of novel aerating flushometer of outstanding effect is installed on pan upper hose and time-delay valve joint portion, and water saving is more than 50%, and the splashproof effect is obvious.

5, for achieving the above object, the utility model is realized by following technology department scheme.

6, spring, spring base, inner core and pressure cap, described inner core is that hollow and bottom are the taper seat trapezium structure, there is pore the spring base side, one convex is arranged at the bottom, have air slot on the convex, spring, inner core pressure cap are installed on successively and form water flow inside passage and outside air opening in the base, and spring can be adjusted the big or small gap that taper seat is combined with convex or is separated with the variation of pressure, the negative pressure of current generation is simultaneously introduced water channel with outside air and is formed gas-vapor mix, reaches water-saving purpose.

7, further, the spring pedestal sidewall has pore, makes inner core and spring base form the air chamber body structure.

8, further, spring pedestal and inner core bonding surface place have air slot, make the cavity between inner core and the spring base form air duct, and when having current to advance in the inner core, air duct can allow outside air owing to principle of negative pressure is sneaked in the water, reaches the purpose of water saving.

9, further, inner core side and bottom have some less than 3 millimeters apertures.

10, further, the outside, spring pedestal bottom, inner core top have the vacant O RunddichtringO of ring shaped slot.

11, further, a convex is arranged at spring top, is used for being stuck in upper hose top during installation.

12, the utility model is a kind of novel aerating flushometer, can be used for squatting just between upper hose and time-delay valve, during assembling O type circle is enclosed within spring pedestal bottom and inner core top respectively, spring is placed on the spring base, inner core is placed in the spring, put pressure cap and the spring base screw thread screws, place the upper hose top of squatting just to add waterproof moat circle and time-delay valve and screw and get final product, and open an aperture (being not that requirement is concentric with spring base sidewall pore) at the upper hose opposite position.Water-saving result can reach more than 50%.

The specific embodiment

19, the utility model is described in further detail below in conjunction with accompanying drawing.

20, embodiment: see also Fig. 1 to Fig. 6, a kind of novel aerating flushometer.Comprise spring base 2, spring 3, inner core 4 and pressure cap 6, described spring base 2 inner chambers are adjusted to the hollow channel in big or small two apertures and formation one convex 20 in it, spring 3, inner core 4 and pressure cap 6 are assembled in successively and form water stream channel in the spring base, inner core 4 bottoms are provided with cone structure 40 and are adjacent to spring base 2 convexes or separate, inner core has outlet at bottom 41 and side weep hole 42, inner core all sides between outlet at bottom and side weep hole are cone structure 40, it forms the water saving runner with 20 weeks of spring pedestal convex along being adjacent to and separating, see also Fig. 3 to Fig. 5, inner core side weep hole is two of symmetry and is arranged at the inner core sidewall, outlet at bottom 41 is some weep holes, centered by one of them weep hole, other are distributed in centre bore week side, see also Fig. 2 and Fig. 6, with upper/lower positions one air inlet 43 is arranged at spring base O RunddichtringO, all sides of spring base convex have three air slots 44.

21, see also Fig. 1 and Fig. 2, inner core water inlet end perisporium be provided with the vacant O RunddichtringO 5 of cannelure and with spring base internal chamber wall mating face seal, the following end of above-mentioned cannelure, contact with spring.The spring base water side is provided with the vacant O-ring seals 1. of cannelure

22, the utility model is used in the time-delay valve jet water spout, operating principle is as follows: tap water is entered into the inner chamber of inner core during use by pressure cap by the spring base water inlet, flow out through the inner core delivery port, the pipe outer air owing to the reason of the negative pressure air inlet by upper hose enter between spring base and inner core cavity and through the conical surface of inner core and spring base convex week along between the gap enter that the formation air water mixes in the upper hose.When water flow pressure is big, current compressing inner core and spring move down the inner core conical surface and spring base convex periphery are adjacent to, thereby water yield will correspondingly reduce, and the pipe outer air enters the also corresponding minimizing of amount that mixes with water in the upper hose with the air slot on the spring base convex; When water flow pressure hour, spring reset also promotes inner core and moves up to make and become big along the gap in inner core taper seat and spring base convex week, thereby the water that enters into inner core weep hole and each weep hole of bottom from the side flows out into spring base outlet water yield and will correspondingly increase, and the pipe outer air enters the also corresponding increase of amount that mixes with water in the upper hose.
