The water replenishing method in the prior art generally adopts an overflow pipe which branches part of water to replenish water for the toilet bowl through a drain valve in the water inlet process of a water inlet valve after the toilet bowl is drained, and the water replenishing method generally has the following defects:
1. when the flushing of the water tank is finished, the water inlet valve starts to feed water and supplement water, and when the beginning part of the water supplement reaches the toilet bowl, the water is siphoned away along with flushing water, so that the water cannot be left in the toilet bowl to play a role of water seal, and the waste of water resources is caused;
2. the water supplementing time of the water inlet valve is the same as the water inlet time of the water inlet valve, and the water supplementing amount is influenced by the water supplementing time and the water supplementing flow rate, so that the water supplementing amount is unstable and is difficult to accurately control, the siphon effect of a toilet is possibly affected by too little water supplementing amount, or water resource waste is caused by too much water supplementing amount;
3. because the water replenishing time of the drain valve in full row is longer than that of the drain valve in half row, under the condition that the water replenishing flow rate of the water inlet valve is unchanged, the water replenishing quantity of the drain valve in full row is larger than that of the drain valve in half row, and when the water replenishing quantity of the drain valve in half row is enough, the water replenishing quantity of the drain valve in full row is too much, and water resource waste can be caused.

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear and obvious, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
First embodiment (the on-off valve 40 employs the linkage control structure of the valve stem 41):
as shown in fig. 1 to 5, an incremental water replenishing device of the present embodiment includes:
a water inlet valve 20 for storing water in the water tank 10, the water tank 10 having a third water stop level controlled by the water inlet valve 20;
an increment mechanism 50 for raising the water storage level of the water tank 10 so that the water level of the water tank 10 rises from the third water stop level to a first water stop level L1;
a water replenishing channel 30, wherein after water in the water tank 10 flows to a toilet water seal through the water replenishing channel 30 to replenish water, the water level of the water tank 10 is reduced from the first water stopping level L1 to a second water stopping level L2;
a switching valve 40 for opening or closing the water replenishment passage 30; wherein the on-off valve 40 opens the water replenishing channel 30 when the water level of the water tank 10 is at the first water stopping level L1, and the water inlet valves stop water inflow when the water level of the water tank 10 is at the first water stopping level L1 or the second water stopping level L2.
The increment mechanism 50:
first type of incremental mechanism: the water inlet valve 20 is provided with a float bowl assembly 21, and the float bowl assembly 21 rises or falls along with the water level change of the water tank so as to control the water inlet valve 20 to stop water or feed water; the increment mechanism 50 includes a weight structure or a magnetic attraction structure provided on the float assembly 21 to delay the rising time of the float assembly 21 and thus delay the water stop of the water inlet valve 20, so that the water level of the water tank 10 rises from the third water stop level to the first water stop level L1.
A second type of incremental mechanism: the water inlet valve 20 is provided with a floating barrel assembly 21 and a water stopping cup 22, and the floating barrel assembly 21 rises or falls along with the water level change of the water stopping cup 22 so as to control the water inlet valve 20 to stop water or feed water; the increment mechanism 50 is formed on the wall of the water stop cup 22, and the water level of the water tank 10 is raised to the first water stop level L1 by raising the wall height to raise the water level of the water tank when the water stop cup is filled with water, so as to delay the rising time of the float assembly 21 and thus delay the water stop of the water inlet valve 20.
The incremental mechanism 50 may employ the first or second or a combination of both, or other incremental mechanisms.
For the first increment mechanism, the water inlet valve only needs to be provided with the float assembly 21, namely, in the case that the float assembly 21 is independently provided without being matched with the water stop cup 22, the mode of controlling the maximum adjustable range of the water supplementing amount can be realized by arranging a counterweight structure for applying counterweight force or magnetic force to the float assembly 21, the distance between the first water stop level L1 and the third water stop level is controlled by controlling the counterweight force or magnetic force of the counterweight structure, specifically, the counterweight water is arranged on the float assembly 21 to provide the counterweight force, after the counterweight water is arranged on the float assembly 21, the float assembly 21 needs larger buoyancy to overcome the counterweight force of the counterweight water, the float assembly 21 floats upwards due to the larger buoyancy, the first water stop level L1 is improved, and after the water stop, the second water stop level L2 of the float assembly 21 is unchanged due to the counterweight force of the counterweight water on the float assembly 21, the distance between the first water stop level L1 and the second water stop level L2 is increased, so that the water stop distance between the first water stop level L1 and the second water stop level L2 can be improved; similarly, the magnetic structure for providing the magnetic force to the float assembly 21 is adopted, after the magnetic force is applied to the float assembly 21, the float assembly 21 needs larger buoyancy to overcome the magnetic force, the float assembly 21 can float upwards due to the larger buoyancy, the first water stop water level L1 is improved, after water is stopped, the float assembly 21 rises and is far away from the magnetic structure for generating the magnetic force to the float assembly 21, so that the magnetic force of the magnetic structure to the float assembly 21 disappears or greatly reduces, the second water stop water level L2 of the float assembly 21 is unchanged, and the interval between the first water stop water level L1 and the second water stop water level L2 can be increased.
Taking a second incremental mechanism as an example, the embodiment is further provided with an adjusting mechanism 60 for adjusting the water supplementing amount, the adjusting mechanism 60 comprises an adjusting piece 61 movably arranged on the water stopping cup 22 and forming a cup wall of the water stopping cup 22, the top of the adjusting piece 61 is the lowest position of the cup wall of the water stopping cup 22, water in the water tank 10 enters the water stopping cup 22 through the top of the adjusting piece 61, and the height of the first water stopping level L1 is adjusted by longitudinally adjusting the adjusting piece 61; in this embodiment, the height of the adjusting piece 61 is adjusted by an adjusting screw 62.
The water replenishing channel 30:
in this embodiment, the water replenishing channel 30 includes an overflow channel 31, a water replenishing pipe 32, and a drain valve overflow pipe 33. Wherein, the water stop cup 22 is provided with a float accommodating cavity 221, and the water supplementing channel 30 comprises a water overflowing channel 31 arranged outside the float accommodating cavity 221. And, the water inlet of moisturizing pipe 32 is linked together with overflow water channel 31, the delivery port of moisturizing pipe 32 with overflow pipe 33 is linked together, overflow pipe 33 is linked together with the closestool water seal, and the height of the delivery port of moisturizing pipe 32 is less than the height of water inlet.
Switching valve 40:
in this embodiment, the switch valve 40 includes a valve rod 41, the valve rod 41 is in linkage fit with the float assembly 21, the valve rod 41 closes the water replenishing channel 30 during the water inlet process of the water inlet valve 20, and when the water level of the water tank 10 rises to the first water stopping level L1, the float assembly 21 drives the valve rod 41 to open the water replenishing channel 30 for replenishing water; the water level of the water tank 10 drops to the second water stop level L2, the water supplementing channel 30 stops supplementing water, and the second water stop level L2 is higher than or equal to the third water stop level.
The water replenishing process of the incremental water replenishing device of this embodiment is briefly described as follows:
as shown in fig. 1, when the water inlet valve 20 starts to inlet water, the valve rod 41 is in sealing fit with the overflow channel 31 of the water-stopping channel 30, preferably, a sealing gasket is arranged on the valve rod 41, and under the combined action of the gravity of the valve rod 41 or the gravity of the valve rod 41 and the water pressure of the water tank 10, the sealing gasket plugs the overflow channel 31 on the water-stopping cup 22, and the water-stopping channel 30 is closed, so that the water in the water tank 10 can only enter the float accommodating cavity 221 of the water-stopping cup 22 beyond the upper edge of the top of the regulating piece 61 or the upper edge of the top of the cup wall of the water-stopping cup to realize water stopping of the water inlet valve 20.
As shown in fig. 2, when the water level of the water tank 10 rises to the first water stop level L1, the float assembly 21 floats upward to drive the valve rod 41 and the sealing gasket to move upward, the overflow channel 31 on the water stop cup 22 is opened, and water in the water tank 10 is supplied to the toilet water seal through the water supply channel 30 formed by the overflow channel 31, the water supply pipe 32 and the drain valve overflow pipe 33. When the water level in the water tank 10 drops to the upper edge of the overflow channel 31, the water replenishing is finished, and at the moment, the water level in the water tank 10 drops to the second water stopping water level L2, namely the final water stopping water level line of the water inlet valve 20, and the buoyancy of the float barrel can still ensure that all functions of the water inlet valve are normal under the water level line state. The water quantity between the first water stopping water level L1 and the second water stopping water level L2 is water supplementing quantity. Further, the relative position of the water stop cup 22 and the regulating piece 61 can be regulated by rotating the regulating screw 62, so that the first water stop level L1 and thus the water supplementing amount can be regulated.
When the drain valve of the water tank 10 drains, the water level of the water tank 10 drops, so that the water level in the water stop cup 22 drops, the float bowl assembly 21 drops to drive the valve rod 41 to close the overflow channel 31 again, and the water replenishing device returns to the state shown in fig. 1 when the water inlet valve starts to feed water.
Second embodiment (on-off valve 40 employs a buoyancy control structure of check valve assembly 42):
as shown in fig. 6 to 10, the main difference between the present embodiment and the first embodiment is that:
differentiation of the water replenishing channel 30:
in this embodiment, the water inlet valve 20 is provided with a float assembly 21 and a water stop cup 22, the water stop cup 22 is provided with a float accommodating cavity 221, the water supplementing channel 30 includes an overflow water channel 31 disposed inside the float accommodating cavity 221 and isolated from the float accommodating cavity 221, and a water supplementing and overflowing hole 331 disposed outside the float accommodating cavity 221, water in the water tank 10 flows to the toilet water seal through the water supplementing and overflowing hole 331 and the overflow water channel 31, and the large check valve 43 is movably attached to the water supplementing and overflowing hole 331 to open or close the water supplementing and overflowing hole 331.
Distinction of the on-off valve 40:
in this embodiment, the switch valve 40 includes a check valve assembly 42, where the check valve assembly 42 is disposed on the water replenishing channel 30 and is opened or closed by the buoyancy or gravity of the check valve assembly 42, the check valve assembly 42 closes the water replenishing channel 30 under the action of the buoyancy of the check valve assembly 42, and when the water level of the water tank 10 rises to the first water stopping level L1, the check valve assembly 42 opens the water replenishing channel 30 under the action of the gravity of water and the gravity of the check valve assembly 42 to replenish water.
The specific structural design of the check valve assembly 42 can be laid out according to the requirement, mainly to form buoyancy during water inflow, to close the water replenishing channel 30 by using the buoyancy, and to lose buoyancy during water stopping, and to open the water replenishing channel 30 by using self gravity. In this embodiment, the check valve assembly 42 includes a large check valve 43 and a small check valve 44, the small check valve 44 is movably attached to the large check valve 43, and the large check valve 43 is movably attached to the overflow hole 31 of the water replenishing channel 30; wherein the large check valve 43 is provided with a water drain hole 431 and a large buoyancy cavity 432, and the small check valve 44 is provided with a small buoyancy cavity 441; the small check valve 44 moves upwards under the buoyancy action of the small buoyancy cavity 441 and closes the water discharge hole 431 of the large check valve 43 in the water inlet process of the water inlet valve 20, the large buoyancy cavity 432 of the large check valve 43 is formed and has buoyancy after the water discharge hole 431 is closed, and the large check valve 43 moves upwards under the buoyancy action of the large buoyancy cavity 432 and the small buoyancy cavity 441 and closes the overflow hole 31 of the water supplementing channel 30; when the water level of the water tank 10 rises to the first water stop level L1, the water in the water tank 10 enters the large buoyancy chamber 432 to make the large check valve 43 lose buoyancy, and the large check valve 43 and the small check valve 44 drop under the gravity of the water and the self gravity and open the water supplementing channel 30 to supplement water.
The water replenishing process of the incremental water replenishing device of this embodiment is briefly described as follows:
as shown in fig. 6, in the water inlet process of the water inlet valve 20, the small check valve 44 moves upwards under the action of the buoyancy to close the water discharge hole 431 of the large check valve 43, so that the large check valve 43 forms a large buoyancy cavity 432; because the buoyancy of the small buoyancy cavity 441 of the small one-way valve 44 and the buoyancy of the large buoyancy cavity 432 of the small one-way valve 44 are larger than the sum of the gravity of the large one-way valve 43 and the gravity of the small one-way valve 44, the large one-way valve 43 and the small one-way valve 44 move upwards together under the action of the buoyancy to close the water supplementing through hole 331 on the water stopping cup 22, so that the water supplementing channel 30 is closed, and water in the water tank 10 can only enter the float accommodating cavity 221 of the water stopping cup 22 beyond the upper edge of the top of the regulating piece 61 or the upper edge of the top of the cup wall of the water stopping cup to realize water stopping of the water inlet valve 20.
As shown in fig. 7, when the water level of the water tank 10 rises to the first water stopping level L1, the float bowl assembly 21 floats up, and the water inlet valve 20 stops water; the water in the water tank 10 enters the large buoyancy cavity 432 of the large one-way valve 43, so that the buoyancy of the large one-way valve 43 disappears, and the large one-way valve 43 and the small one-way valve 44 fall together due to the fact that the sum of the gravity of the water entering the large one-way valve 43 and the gravity of the large one-way valve 43 and the small one-way valve 44 is larger than the buoyancy of the small buoyancy cavity 441 of the small one-way valve 44, so that the water supplementing and overflowing hole 331 on the water stopping cup 22 is opened; the water in the water stopping cup 22 is supplemented to the toilet water seal through the water supplementing channel 30 formed by the overflow water channel 31, the water supplementing pipe 32 and the drain valve overflow pipe 33, meanwhile, the water in the water tank 10 is supplemented to the water stopping cup 22 through the water supplementing through hole 331, the liquid level inside and outside the water stopping cup 22 is ensured to be consistent, when the water level in the water tank 10 drops to the upper edge of the water supplementing channel, the water supplementing is finished, at the moment, the water level in the water tank 10 drops to the second water stopping water level L2, namely the final water stopping water level line of the water inlet valve 20, and the buoyancy of the floating barrel can still ensure that all functions of the water inlet valve are normal under the water level line state. The water quantity between the first water stopping water level L1 and the second water stopping water level L2 is water supplementing quantity. Further, the relative position of the water stop cup 22 and the regulating piece 61 can be regulated by rotating the regulating screw 62, so that the first water stop level L1 and thus the water supplementing amount can be regulated.
When the drain valve of the water tank 10 drains, the water level of the water tank 10 drops, so that the water level in the water stop cup 22 drops, the small one-way valve 44 also drops after losing buoyancy, the drain hole 431 of the large one-way valve 43 is opened after the small one-way valve 44 drops, water in the large one-way valve 43 is drained through the drain hole 431, and the water supplementing device returns to the state shown in fig. 6 in the water supplementing process of the water inlet valve.
Correspondingly, the invention also provides an incremental water supplementing method, which comprises the following steps of:
a. raising the water storage level of the water tank 10, raising the water level of the water tank 10 from a third water stopping level controlled by a water inlet valve to a first water stopping level L1, wherein the water inlet valve 20 stops water inlet;
b. when the water level of the water tank 10 is at the first water stop level L1, the water supplementing channel 30 is opened by the switch valve 40, and after the water of the water tank 10 flows to the toilet water seal through the water supplementing channel 30 for supplementing water, the water level of the water tank 10 is reduced to a second water stop level L2;
c. when the water level of the water tank 10 drops to the second water stop level L2, the water supply passage 30 stops supplying water; when the water level of the water tank 10 is at the first water stop level L1 or the second water stop level L2, the water inlet valve 20 stops water inlet.
It should be noted that, the third water stop level of the water tank 10 controlled by the water inlet valve 20 is a level that the water inlet valve 20 can make the water tank 10 reach when the increment mechanism 50 is removed and the increment mechanism 50 is matched with the water inlet valve 20, so that the water inlet valve 20 can continue to feed water after the water reaches the third water stop level, thereby realizing the purpose of increasing the water storage level of the water tank 10. Of course, the increment mechanism 50 and the inlet valve 20 may be independent from each other, that is, the inlet valve 20 stops the water feeding when the water tank level rises to the third water stop level, and after the inlet valve 20 stops the water feeding, the increment mechanism 50 (which may be another inlet valve, which may be mechanical or electrically controlled) opens the water feeding so that the water level of the water tank 10 rises from the third water stop level to the first water stop level L1, which is also possible.
It should be noted that, in the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described as different from other embodiments, and identical and similar parts between the embodiments are all enough to be referred to each other.
