Abstract
The utility model discloses a water inlet valve anti-siphonage structure, which includes a water inlet pipe, a water inlet body and a lifting rod; a water-stop rubber pad is equipped at top of the water inlet pipe; an anti-siphonage structure extends at upper side of the water inlet body; an anti-siphonage rubber pad is fixed on a water outlet channel at upper part of the anti-siphonage structure, and an air inlet hole is positioned at the top the anti-siphonage structure. Since the anti-siphonage structure of the utility model is at one side of the water inlet body with adjustable height, distance between top of the water inlet valve and the anti-siphonage rubber pad is shortened to raise the water level in the water tank and increase the fall in the water tank and thus improve flushing capacity of the toilet.
Description
Technical field
The utility model is the anti-syphon structure of water intaking valve that is applied to the bathroom water tank about a kind of.
Background technology
According to the relevant standard-required of present country, the water inlet system of bathroom need be provided with anti-siphon means, avoids polluted source with this.
Existing tank intake valve of water anti-siphon means, as " a kind of anti-siphon means of water intaking valve " of Chinese utility model patent 03217430.6, it is to be provided with splitter, sealing rubber cushion and anti-siphon rubber cushion on the top of water intaking valve; Splitter is provided with mutual disconnected inlet channel, and inlet channel is communicated with water inlet pipe; The sealing rubber cushion is located at the inlet channel outlet, and anti-siphon rubber cushion covers in the splitter upper end.Promote anti-siphon, the anti counter-flowing ability of water intaking valve with this.
But the detailed water intaking valve of seeing said structure, anti-siphon rubber cushion is provided in a side of the top of sealing rubber cushion, and be positioned at the upper end of water intaking valve, then cistern water level is height-limited in this anti-siphon rubber cushion position, distance between water intaking valve top and the floating drum can't further shorten, thereby can't utilize the space of water tank as much as possible, and flood.
The utility model content
The purpose of this utility model is to provide a kind of water intaking valve to prevent syphon structure, and it can effectively shorten the distance between water intaking valve top and the anti-siphon rubber cushion, to improve the height of cistern water level, increases the height of water of water tank.
For achieving the above object, solution of the present utility model is: a kind of water intaking valve is prevented syphon structure, comprises water inlet pipe, water inlet body and arguing for the sake of arguing; The top of water inlet pipe is provided with the sealing rubber cushion; Wherein extend an anti-siphon mechanism in water inlet body top one side, be provided with intake tunnel that communicates with water inlet pipe and the exhalant canal that communicates with the water inlet body in the anti-siphon mechanism, anti-siphon rubber cushion is located in the exhalant canal on anti-siphon mechanism top, and the top of anti-siphon mechanism is provided with air inlet.
Anti-siphon mechanism comprises anti-siphon pedestal and anti-siphon lid, is provided with air inlet at anti-siphon tops, and anti-siphon rubber cushion is actively installed between anti-siphon pedestal and the anti-siphon lid.
Anti-siphon mechanism is one " L " type, and its top is to be higher than into water bodies top.
After adopting such scheme, because anti-syphon structure of the present utility model, be provided in a side of an into side of water body, then it highly can effectively improve, thereby shorten the distance between water intaking valve top and the anti-siphon rubber cushion, improve the height of cistern water level with this, increase the height of water of water tank, improve the rinse capability of toilet.

The specific embodiment
As shown in Figure 1, 2, anti-syphon structure of the present utility model mainly includes into water body 1, water inlet pipe 2, argues for the sake of arguing 3 and sealing rubber cushion 4, and sealing rubber cushion 4 places loam cake 5 and is matched with the top of water inlet pipe 2, loam cake 53 is combined together with arguing for the sake of arguing, and 3 the other end of arguing for the sake of arguing connects floating drum 6;
Key of the present utility model is: one side is extended with an anti-siphon mechanism 7 on water inlet body 1 top, should anti-siphon mechanism 7 be one " L " type, the height at its top is higher than the into top of water body 1, it comprises anti-siphon pedestal 71, anti-siphon lid 72 and anti-siphon rubber cushion 73, is provided with intake tunnel 74 that communicates with water inlet pipe 2 and the exhalant canal 75 that communicates with water inlet body 1 in anti-siphon pedestal 71; Anti-siphon lid 72 is provided with air inlet 721, and anti-siphon rubber cushion 73 is actively installed between anti-siphon pedestal 71 and the anti-siphon lid 72, and is arranged in intake tunnel 74.
Shown in Fig. 3,3A, when water intaking valve in when water inlet, the water of water inlet pipe 2 can upwards boost sealing rubber cushion 4, water can enter in the intake tunnel 74 of anti-siphon mechanism 7, to prevent that simultaneously siphon rubber cushion 73 upwards boosts, water just can enter exhalant canal 75 and enter in the water tank along water inlet body 1, thereby finishes a injecting process.
Shown in Fig. 4,4A, when water tank fills with water and water inlet pipe form a vacuum owing to cutting off the water supply, sealing rubber cushion 4 and the anti-siphon rubber cushion 73 of this moment fall, cooperate among the figure shown in the arrow, atmosphere communicates with the water route by air inlet 721, thereby effectively prevent the generation of siphon, backflow, avoid polluted source with this.
To sum up, because anti-syphon structure of the present utility model, be provided in a side of an into side of water body 1, then it highly can effectively improve, thereby shorten the distance between water intaking valve top and the anti-siphon rubber cushion 73, improve the height of cistern water level with this, increase the height of water of water tank, improve the rinse capability of toilet.
