Problems solved by technology

[0002] Existing toilets generally replenish water to the water seal at the bottom of the toilet bowl after flushing to ensure sufficient water seal water volume to avoid indoor air pollution from the odor of the sewage channel. In the prior art, the water replenishment channel is generally set. Size (that is, the cross-sectional area of ​​the replenishment channel) to control the amount of water replenishment, that is, when the cross-sectional area of ​​the replenishment water channel is larger, the amount of water replenishment is also larger, and vice versa; on the other hand, when the toilet in the prior art uses When the drain valve of the double flushing structure is used to realize double flushing of large and small sizes, the water replenishment volume of small flushing and large flushing is usually inconsistent. Generally, the same replenishment channel is used for replenishment of large and small flushes, that is, the water replenishment channels of large and small flushes are of the same size. In this case, the large flushing time is longer and the replenishment amount is larger, and the small flushing time is shorter and the replenishment amount is smaller. Congress causes some hydration to be wasted
In addition, there are also some double-flush toilets that require a large amount of water replenishment for small flushes, but small amounts of water replenishment for large flushes. In this way, the prior art cannot separately control the amount of water replenishment for large and small flushes, so the above-mentioned requirements for double-flush toilets cannot be met.

Embodiment 1

[0064] Embodiment one (wrench switch):

[0065] Such as Figure 1 to Figure 6 As shown, a water supply device for a dual-flush toilet according to Embodiment 1 of the present invention, the water supply device includes a water supply body 20 and a buoy 30, the water supply body 20 is provided with a water supply control chamber 21, a water inlet 22, and a water outlet 23. The water discharge port 24 and the water replenishment volume adjustment port 25 communicated with the water replenishment control chamber 21 , and the switching member 26 that cooperates with the large flush switch 10 a and the small flush switch 10 b in linkage.

[0066] In this embodiment, the buoy 30 moves up and down with the change of the water level in the water replenishment control chamber 21 to open or close the water outlet 24, and controls the water outlet 23 by controlling the opening and closing of the water outlet 24 to stop the water outlet first. set time period or the second preset time pe...

Embodiment 2

[0084] Embodiment 2 (button switch):

[0085] Such as Figure 7 to Figure 10 As shown, the water supply device 20 of this embodiment is the same as that of Embodiment 1. The difference between this embodiment and Embodiment 1 is that this embodiment does not use wrench-type large and small flush switches 10a, 10b, but adopts button-type The large and small punch switches 10a, 10b are movably installed on the key base 50, and the pressed block on the switching piece 26 is located below the key. When the key is pressed, the key drives the bottom of the pressed piece, thereby rotating the switching piece 26. To realize the linkage and cooperation between the button and the switching element, the other undescribed structures, principles and working processes are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0086] Embodiment three (hydration method)

[0087] In addition, according to the water supply device for a dual-flush toilet provided by the present invention, the present invention also provides a water supply method for a double-flush toilet, which is used to control the amount of water replenishment of the water seal in the double-flush toilet. There is a small flush switch 10b for controlling small flush water and a large flush switch 10a for controlling large flush water, and the method for replenishing water includes the following steps:

[0088] Provide a water replenishment body 20, the water replenishment body 20 is provided with a water replenishment control chamber 21, and is provided with a water inlet 22 and a water outlet 23 communicating with the water replenishment control chamber 21;

[0089] A buoy 30 is provided, so that the buoy 30 can be movable up and down in the water replenishment control chamber 21;

[0090] When the buoy 30 responds to the big flush...

Abstract

The invention discloses a water supplementing device for a double-flushing closestool and a water supplementing method. The water supplementing device comprises a water supplementing body and a buoy, wherein the water supplementing body is internally provided with a water-supplementing control cavity and is provided with a water inlet and a water outlet communicated with the water-supplementing control cavity; and the buoy is arranged in the water-supplementing control cavity in a manner of up-down movement. The water supplementing device and the water supplementing method disclosed by the invention have the advantages that the buoy is arranged in the water supplementing body, and responses a large-flushing switch and a small-flushing switch to make the periods of time for stopping water discharge of the water outlet different or make the water outlet have the flowing speeds corresponding to the different periods of time, so that first water supplementing amount and second water supplementing amount are realized; the structure is novel, the concept is ingenious, the water supplementation is reliable and the matching performance is strong. In addition, the invention also provides the water supplementing method for the double-flushing closestool.
