Description
A TOILET FILL VALVE
The present invention relates to the field of toilet parts, and more specifically relates to a toilet fill valve.
As the quality of life and standard of living improve, consumers also set a higher standard for toilet and bathroom accessories. Although an existing toilet fill valve in a toilet tank already has a firm and stable structure and a long service life, it still has some obvious defects. A common toilet fill valve usually comprises a valve, a float ball and an adjustment rod connected between the valve and the float ball for motion transmission. The valve comprises an inlet tube, an outlet tube, and a stopper that serves to communicate or block the communication between the inlet tube and the outlet tube. As the float ball goes up or down along with the change in water level in the tank, the adjustment rod will then be driven up or down as well to drive the stopper to communicate or block the communication between the inlet tube and the outlet tube, thereby allowing the fill valve to fill in water or to stop filling in water. The inlet tube is usually positioned vertically, while the outlet tube is positioned at an upper end of the inlet tube. Water enters the fill valve from a bottom end of the inlet tube, and enters the toilet tank through the outlet tube. There are mainly several ways water can enter the toilet tank through the outlet tube: 1. Water enters into the toilet tank directly through the mouth of the outlet tube; however, noise is noticeable due to the difference in height between the outlet tube and the bottom of the tank; 2. Water enters into the tank from the outlet tube through a guiding tube which has one end connected to the mouth of the outlet tube and another end leading to the bottom of the toilet tank; noise is reduced since water reaches the bottom of the toilet tank through the guiding tube, however, when the valve and the guiding tube are empty without water, negative pressure is formed, resulting in backflow of water from the toilet tank, thus affecting the normal use of the fill valve.
An object of the present invention is to provide a toilet fill valve that can prevent backflow of water from the toilet tank, and can reduce the noise when water enters the toilet tank through the toilet fill valve.
The present invention has the following technical solutions: A toilet fill valve, comprising a valve, an adjustment rod, a float and a guiding shell; the valve comprises an outlet tube positioned at an upper portion of the valve, an inlet tube at a lower portion of the valve, and a stopper that communicates or stops communication between the outlet tube and the inlet tube; the outlet tube has a mouth for water outlet; the float is connected with the adjustment rod; the float moves up or down along with changes of water level in a toilet tank to drive the adjustment rod which in turns drives the stopper to communicate or stop communication between the outlet tube and the inlet tube; the guiding shell sleeves the float; an inner wall of the guiding shell and an outer wall of the float form a clearance fit; the guiding shell comprises a guiding structure that guides water to flow on the inner wall of the guiding shell; the guiding structure is positioned below the mouth of the outlet tube and above the float.
The guiding structure comprises an overflow opening provided on the guiding shell, a plurality of guiding ribs substantially vertical provided around a periphery of the overflow opening, and a guiding plate connecting bottom ends of the guiding ribs.
Each of the guiding ribs is provided with a guiding slanted surface; the guiding slanted surface is slanted from a top end of the respective guiding rib at the periphery of the overflow opening down along a direction towards a center of the guiding plate.
The mouth of the outlet tube and the overflow opening are both in circular shape; a diameter of the overflow opening is larger than a diameter of the mouth.
The center of the guiding plate is provided with a discharge opening.
The float has a barrel shape, comprising an enclosing side wall, a horizontal plate provided within a space enclosed by the enclosing side wall and positioned at a substantially middle part of the float; the horizontal plate is provided with a water release opening.
A diameter of the water release opening is smaller than a diameter of the discharge opening.
An outer side wall of the float is provided with a plurality of float ribs; the float ribs abut against the inner wall of the guiding shell.
The toilet fill valve also comprises a buffering unit at the mouth; the buffering unit comprises a buffering grid net and a flow regulating plate having meshes positioned beneath the buffering grid net.
Meshes of the buffering grid net are bigger than the meshes of the flow regulating plate.
The flow regulating plate is a stainless steel filter net.
The present invention uses an additional guiding shell surrounding the float, so that water flowing out from the outlet tube is buffered by the guiding structure and the guiding shell, and eventually flows on the inner wall of the guiding shell down into the toilet tank, thereby greatly reducing the noise of refilling water into the toilet tank through the valve, and also preventing backflow of water from the toilet tank.
Use of the buffering unit further enhances the effect of noise reduction and can effectively route the flow of water and reduce turbulence.

FIG. 8 is a structural view of a buffering unit according to an embodiment of the present invention.
A toilet fill valve, comprising a valve 10, an adjustment rod 20, a float 30 and a guiding shell 40.
The valve 10 comprises an outlet tube 11 positioned at an upper portion of the valve, an inlet tube 12 at a lower portion of the valve, and a stopper 13 that communicates or stops communication between the outlet tube 11 and the inlet tube 12; the outlet tube 11 has a mouth 111 for water outlet.
The float 30 is connected with the adjustment rod 20; the float 30 moves up or down along with changes of water level in a toilet tank to drive the adjustment rod 20 which in turns drives the stopper 13 to communicates or stops communication between the outlet tube 11 and the inlet tube 12.
The guiding shell 40 sleeves the float 30; an inner wall of the guiding shell 40 and an outer wall of the float 30 form a clearance fit; the guiding shell 40 comprises a guiding structure that guides water to flow on the inner wall of the guiding shell 40; the guiding structure is positioned below the mouth 111 of the outlet tube and above the float 30.
FIGs. 1-8 illustrate an embodiment of the present invention.
The outlet tube 11 is positioned at a top end of the inlet tube 12; a bottom end of the inlet tube 12 is a water inlet; water enters the valve 10 from the bottom end of the inlet tube 12, goes up the valve 10, and finally flows out from the mouth 111 of the outlet tube 11.
The guiding structure comprises an overflow opening 41 provided on the guiding shell 40, a plurality of guiding ribs 42 substantially vertical provided around a periphery of the overflow opening 41, and a guiding plate 43 connecting bottom ends of the guiding ribs 42. In the present embodiment, there are four guiding ribs 42; a gap between each pair of adjacent guiding ribs 42 forms a guiding space.
Each of the guiding ribs 42 is provided with a guiding slanted surface 421; the guiding slanted surface 421 is slanted from a top end of the respective guiding rib at the periphery of the overflow opening 41 down along a direction towards a center of the guiding plate 43.
The mouth 111 of the outlet tube 11 and the overflow opening 41 are both in circular shape; the overflow opening 41 is positioned right beneath the mouth 111; a diameter of the overflow opening 41 is larger than a diameter of the mouth 111; the guiding plate 43 also has a circular shape; a diameter of the guiding plate 43 is similar to the diameter of the of the overflow opening 41; the center of the guiding plate 43 is provided with a discharge opening 431. Water flows down to the guiding plate 43 from the mouth 111; a first portion of water which makes up most of the water flowing down from the mouth 11 will disperse omnidirectionally on the guiding plate 43 and then flow through the guiding space between each pair of adjacent guiding ribs 42 to the inner wall of the guiding shell 40; this first portion of water flows on the inner wall of the guiding shell 40 down to the toilet tank through clearances between the guiding shell 40 and the float 30; a second portion of water which makes up the rest of the water flowing down from the mouth 11 will flow down to the float 30 beneath the guiding structure through the discharge opening 431. The guiding ribs 42 and the guiding slanted surface 421 are provided to route the flow of water in order to reduce noise. Also, the flow of water is dispersed omnidirectionally on the guiding plate 43, and eventually flows out from the guiding spaces onto the inner wall of the guiding shell 40 and finally down to the toilet tank. Omnidirectional dispersal of water and the guiding function of the inner wall of the guiding shell 40 help further reduce noise of the flow of water.
The float 30 has a barrel shape, comprising an enclosing side wall 31, a horizontal plate 32 provided within a space enclosed by the enclosing side wall 31 and positioned at a substantially middle part of the float 30; the horizontal plate 32 is provided with a water release opening 321; a diameter of the water release opening 321 is smaller than a diameter of the discharge opening 431; a counterweight trough 30A is formed between the horizontal plate 32 and the enclosing side wall 31 of the float 30 above the horizontal plate; water drops from the discharge opening 431 down to the counterweight trough 30A of the float 30, such that the float 30 will move up only when the buoyancy exerted to the float 30 by the water in the toilet tank is greater than the sum of the weight of the float 30 itself and the weight of the water in the counterweight trough 30A. When the float 30 moves up, it drives the stopper 13 to stop water inlet, and after that, the water inside the counterweight trough 30A will eventually drop into the toilet tank through the water release opening 321.
An outer side wall of the float 30 is provided with a plurality of float ribs 33; the float ribs 33 abut against the inner wall of the guiding shell 40, so that the clearances 30B that guide the flow of water are formed between the float 30 and the guiding shell 40.
The present invention also comprises a buffering unit at the mouth 111. The buffering unit comprises a buffering grid net 112 and a flow regulating plate 50 having meshes positioned beneath the buffering grid net 112.
Meshes of the buffering grid net 112 are bigger than the meshes of the flow regulating plate 50; the buffering grid net 112 is formed integrally with the valve 10. The buffering grid net 112 buffers the high speed of water flow in the outlet tube 11, thereby achieving a certain degree of noise reduction.
The flow regulating plate 50 is a stainless steel filter net. It effectively routes the flow of water and reduces turbulence. Also, it disperses the flow of water so that water flows out from the outlet tube 11 evenly, thereby reducing noise.
The present invention uses an additional guiding shell 40 surrounding the float 30, so that water flowing out from the outlet tube 11 is buffered by the guiding structure and the guiding shell 40, and eventually flows on the inner wall of the guiding shell 40 down into the toilet tank, thereby greatly reducing the noise of refilling water into the toilet tank through the valve 10, and also preventing backflow of water from the toilet tank.
Use of the buffering unit further enhances the effect of noise reduction and can effectively route the flow of water and reduce turbulence.
