Description

Outlet structure of toilet tank

The invention relates to a water outlet structure of a toilet water tank, in particular to a water outlet structure which can prevent the flowing water flowing out of the toilet water tank from flowing back into the toilet water tank.

In the prior art, the functions of the old drain valve only include the functions of stopping water and draining, that is to say, the old drain valve only has a structure of an outlet channel and an inlet channel. This type of drain valve does not block the water flowing out of the water tank from flowing back into the water tank again, and may cause the water flowing out of the water tank to be contaminated due to contact with the dirty drain valve. When this contaminated water flow flows back into the water tank again , Will make the water source inside the water tank also contaminated. Therefore, with the increasing industry, only the old drain valve with the outlet channel and the inlet channel is improved into a three-way drain valve with the outlet channel, the inlet channel and a drain channel.

In addition, in the present invention, the valve assembly is arranged in the valve accommodating space and directly abuts the cover body, which can specifically simplify the water outlet structure without reducing the function of the water outlet structure.

The detailed description and technical content of the present invention are explained in conjunction with the drawings as follows:

Please refer to FIGS. 1 and 3. The present invention provides a water outlet structure 100 of a toilet water tank. The water outlet structure 100 must be used with a toilet water tank 200. Further, the toilet water tank 200 has a water outlet 201 for the water outlet structure 100. . The water outlet structure 100 will be described in detail. The water outlet structure 100 includes a pair of cover bodies 10 and a valve assembly 20 that should be disposed at the water outlet. Specifically, the cover body 10 is an integrally formed structure, and a valve accommodating space 11, a water outlet 12 communicating with the valve accommodating space 11, and a valve accommodating space are formed in the cover body 10 The drain 13 of the space 11. The installation position of the drain channel 13 will be located on the upper edge of the cover body 10, that is, the position that is located away from the water outlet 201 relative to the water channel 12. Further, the water outlet 12 is formed with a water outlet 121, and the water outlet 13 is formed with a water outlet 131. An angle 122 may be formed between the water outlet 121 and the water outlet 131. The water outlet 121 can be connected to a switching valve of the toilet seat nozzle, so that the water passage 12 can supply a water flow to the toilet seat nozzle during the implementation process.

On the other hand, referring back to FIGS. 1 and 4, the valve assembly 20 includes a spring 21 and a valve block 22. Specifically, the spring 21 is disposed in the drain 13, and the valve block 22 is connected to the spring 21 and located in the valve accommodating space 11. That is to say, during the assembly process, the spring 21 is first placed in the drain 13, and then, the valve block 22 is sleeved in the spring 21, partly in the drain 13, and the rest in The valve contains space 11. In more detail, the spring 21 has a first end 211 against the cover 10 and a second end 212 connected to the valve block 22. In addition, the valve block 22 has a water-blocking position where the spring 21 abuts against the water outlet 201, and is pushed by the flowing water in the toilet tank 200 to release the water outlet 201 and stop the drain channel 13 water supply location.

Next, please refer to FIG. 4 and FIG. 7, an embodiment of the water outlet structure 100 will now be described. First, assume that the valve block 22 is in the water stop position because it is not pushed by the toilet tank 200 in the initial state. When the valve block 100 is in the water stop position, the water outlet structure 100 will enter a water outlet. The reverse flow of 12 can only enter the anti-backflow mode of the drain 13. In other words, at this time, the pressure in the outlet structure 100 is less than the atmospheric pressure, so that the flowing water originally located in the outlet structure 100 will not be discharged outward, and the resisting force of the spring 21 will be greater than that in the toilet tank 200 The pushing force of the flowing water causes the valve block 22 to be pressed against the spring 21 to close the water outlet 201. According to this, the reverse flow water entering from the water outlet channel 12 can only flow into the drain channel 13, and is discharged to the outside of the water outlet structure 100 through the drain hole 131. In other words, the reverse flow water cannot continue to flow into the toilet tank 200, and at this time, the reverse flow water will be discharged from the drain 13 (as shown in FIG. 5). Once the valve block 22 is located at the water supply position again, that is, the pressure in the water outlet structure 100 will be greater than atmospheric pressure again, the valve block 22 will be displaced toward the drain 13 by the action of the flowing water in the toilet tank 200, At this time, the spring 21 is compressed by the valve block 22, and the valve block 22 will temporarily close the drain channel 13, so that the flowing water no longer flows into the drain channel 13. On the other hand, the water outlet 201 will be released so that the water flowing in the toilet tank 200 can flow to the water outlet 12, and then the water flowing in the water outlet structure 100 will be continuously discharged from the water outlet 121 (as shown in FIG. 6 ), that is to say, the water outlet structure 100 will enter a water supply mode from the anti-backflow mode. In addition, to stop the outlet structure 100 from discharging the flowing water from the outlet hole 121 again, it is only necessary to make the pushing force of the spring 21 greater than the pushing force of the flowing water in the toilet tank 200 to push the valve block 22, which is to make the The spring 21 is released, and then the valve block 22 is displaced to the water stop position again, so that the water outlet structure 100 can be switched from the water supply mode to the anti-backflow mode.

As can be seen from the above, the water outlet structure 100 of the toilet tank of the present invention is switched through the position of the valve block 22, so that the water outlet structure 100 has the backflow prevention mode and the water supply mode. That is to say, when the water outlet structure 100 is switched from the water supply mode to the backflow prevention mode, the water flowing in the water outlet structure 100 will not flow back into the toilet tank 200, but is discharged through the drain hole 131. Therefore, the flowing water will not be backflowed into the toilet tank 200 again, and there is no doubt of polluting the water source. In addition, in the present invention, only the spring 21 and the valve block 22 are arranged in the water outlet structure 100, which can achieve the same function of the conventional water outlet structure, and can specifically simplify the structure of the water outlet structure 100, so that the water outlet structure 100 Developers can quickly produce.

Next, please refer to FIG. 4, in order to make the water outlet structure 100 can be used with the water outlet 201, in one embodiment, the cover 10 has an installation opening 14 facing the water outlet 201. The caliber is set larger than the water outlet 201. That is to say, when the water outlet structure 100 is assembled on the water outlet 201, the installation opening 14 is used to accommodate the water outlet 201. When the valve block 22 is located in the valve accommodating space 11, the valve block 22 can Contact the water outlet 201 and close the water outlet 201.

In addition, please also refer to FIG. 5 and FIG. 6, in order to make the outlet 12 and the drain 13 can be separated, and the valve block 22 can completely close the drain 13 during the implementation process. In one embodiment, The cover 10 includes an outer wall 16 and an inner wall 17 disposed in the space enclosed by the outer wall 16. The water outlet 12 is defined between the outer wall 16 and the inner wall 17, and the space enclosed by the inner wall 17 defines the drain 13. In other words, the water outlet 12 and the water outlet 13 are separated by the inner wall 17. Furthermore, the inner wall 17 protrudes relative to the installation opening 14. In other words, when the water outlet structure 100 is installed on the toilet tank 200, the valve block 22 will be affected. When the valve block 22 is in the water supply position, the valve block 22 will abut the inner wall 17 and The drain channel 13 is closed, and when the valve block 22 is displaced to the water stop position, the valve block 22 will move away from the inner wall 17 and close the water outlet 201. At this time, the drain channel 13 and the outlet The water channels 12 will communicate with each other. Next, the drain channel 13 will be further described. The drain channel 13 includes an assembly section 132 provided for the spring 21, and a drainage section 133 connected to the assembly section 132 and formed with the drainage hole 131. Further, the assembly section 132 and the drain section 133 respectively have an extension line 134, 135, and the two extension lines 134, 135 will intersect at a point 136. That is to say, after the assembly is completed, the group connecting section 132 will be located on the water outlet 201, and the valve block 22 will be moved back and forth between the group connecting section 132 and the water outlet 201 during the implementation process.

On the other hand, please refer to FIG. 5 and FIG. 6 again, in order to limit the valve block 22 to prevent the valve block 22 from displacement during the implementation process, and at the same time, in order for the valve block 22 to reliably close the drain 13 and the outlet The water port 201 enables the valve block 22 to further have a connecting post 221 connected to the spring 21, a stopper 222 connected to the connecting post 221 and covering the drain 13 and a stopper provided on the stopper The sheet 222 is not provided with a guide post 223 on one side of the connecting post 221 and can extend into the water outlet 201. Specifically, the connecting post 221 is disposed in the assembly section 132, and prevents the valve block 22 from displacement to the left and right of the water outlet structure 100, and the stopper 222 is located in the valve accommodating space 11, and The diameter of the stopper piece 222 is set to be larger than the diameters of the assembly section 132 and the water outlet 201, to ensure that the valve block 22 can reliably close the water outlet 201 when in the water stop position, and when in the water supply position The drain channel 13 can be sealed. Furthermore, the stop piece 222 must be a structure without holes. The purpose is that the stop piece 222 needs to withstand the pushing effect of the flowing water in the toilet tank 200 and be displaced toward the drain 13. In addition, the guide column 223 is used to limit the valve block 22 to prevent the valve block 22 from being displaced relative to the water outlet 201 due to the water flowing in the toilet tank 200.

According to the above, in one embodiment, the connecting column 221 may have at least one first water guide gap 224, the first water guide gap 224 is used to guide the reverse flow water to flow smoothly from the outlet channel 12 to the drain channel 13, and the The guiding column 223 may have at least one second water guiding gap 224. The second water guiding gap 224 can guide the flowing water in the toilet tank 200 and push the stopper 222 more easily to make the stopper The piece 222 is displaced in the direction of the drain 13. That is to say, in the present invention, through the arrangement of the first water guide gap 224 and the second water guide gap 225, the cross section of the connecting column 221 and the cross section of the guide column 223 respectively exhibit an X shape, which is being developed During the process, the first water conducting gap 224 and the second water conducting gap 225 are not limited to what is depicted in the figure, and can be adjusted according to implementation requirements.

In summary, the above is only a preferred embodiment of the present invention, and it should not be used to limit the scope of the present invention, that is, any changes and modifications made according to the scope of the patent application of the present invention should still belong to the present invention Of patent coverage.
