Description

Technical Field

[0001] The utility model relates to the technical field of intelligent toilets, in particular to a multifunctional valve group for realizing water inlet and non-electricity flushing of toilets. Background Art

[0002] At present, the existing smart toilet flushing generally adopts two forms. One is a water tankless toilet, which is directly connected to the municipal water through a water inlet pipe and opened and closed by an electrically controlled switch valve to realize the flushing of the toilet brush ring and the main flushing water replenishment. However, this water tankless method cannot open the electrically controlled switch valve in a power outage, resulting in the toilet flushing function being unusable; more importantly, the flushing water pressure of this water tankless method comes from the water pressure in the municipal water pipe (tap water pipe). When the pressure is low or the water pressure fluctuates greatly, it is difficult to flush and form a siphon, especially in existing commercial housing. For middle and high-level users, it is difficult to meet the flushing needs; the other is a toilet with a water tank version, but the existing water tank is a built-in water tank, that is, the water tank is built into the rear end of the toilet, and its height is lower than or flush with the smart cover, which is no longer like the high water level design of the traditional toilet. Although this type of water tank saves space and has high aesthetics, the water level in the water tank is low, and a high-power water pump is needed to pump water to increase potential energy to meet the flushing needs; in addition, when there is a power outage or short circuit and the power supply cannot be supplied, the water pump cannot work to pump water, that is, flushing cannot be achieved, resulting in a poor user experience of this product;

[0003] To this end, some manufacturers set a manual switch in addition to the electric control switch valve to manually start flushing when the power is off. However, there is still a very important defect, that is, the flushing potential energy is insufficient and cannot be flushed cleanly, which leads to poor hygiene of the entire toilet. The main reasons are as follows: (1) The height difference between the water level and the toilet brush ring and the main flush position is too small, even lower than the height of the brush ring. Such low water pressure cannot generate potential energy; (2) After opening, the brush ring and the main flush are flushed directly at the same time. After the flow is divided, the potential energy is greatly reduced. When the water flows through the long and far brush ring waterway, its potential energy is almost reduced to a flowing water state, without impact force, and the toilet dirt-bearing surface (commonly known as the pot surface) cannot be flushed cleanly;

[0004] In summary, the existing water inlet components still need to be further improved to meet actual usage requirements. Utility Model Content

[0019] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0020] (1) The utility model provides a multifunctional valve group for realizing water inlet and non-electric flushing of the toilet. It has a simple structure, is easy to manufacture, easy to realize and has low cost, and solves the problem that the existing intelligent toilet cannot work normally and has no potential energy for flushing when the power is off. The utility model retains the electronically controlled flushing of the intelligent toilet and switches to mechanical flushing when the power is off, and can also provide a flushing form with potential energy. On the basis of mechanical flushing, only by improving the original valve group structure for water inlet, without increasing the volume and without affecting the water storage space of the water tank, it can also realize the flushing of the brush ring, the main flushing and the water seal replenishment in sequence, breaking the problem that some existing mechanical switches can only realize the flushing of the brush ring water channel, the main flushing water channel and the water seal replenishment water channel at the same time, so that the potential energy of flushing is greatly reduced; flushing in sequence The method makes the water volume and potential energy sufficient, and the flushing is cleaner; at the same time, the utility model also sets the first water pass part to a jet state. The water pressure when it is opened impacts the static water in the connecting pipe, so that it forms a Venturi phenomenon, and a large amount of water in the water tank is sucked in, thereby increasing the flushing potential energy again. Even for a long flow channel such as the brush circle water channel, sufficient potential energy can be guaranteed for flushing, and the water in the entire water tank is used for brush circle flushing, and is not shared with the subsequent main flushing water channel, so there is sufficient water volume; in summary, the multifunctional valve group provided by the utility model brings the following effects at the same time: small size, ensuring the water storage capacity of the water tank; when there is electricity, the water inlet component is only used for conventional water tank replenishment. If there is electricity, it can be used as a flush valve to form multiple water channels for flushing in sequence, and the flushing potential energy is strong.

[0021] (2) The utility model sets the water inlet end of the connecting pipe corresponding to the first water pass portion lower than the water inlet chamber; thus, a height difference is formed between the water inlet chamber and the water inlet end of the connecting pipe, so that during the water inlet process, the water flow forms a certain impact potential energy, which, combined with the mouth of the jet, makes it easier for the mouth of the connecting pipe and the interior to form a Venturi phenomenon, thereby sucking the water flow in the water tank into the connecting pipe.

[0022] (3) A water passage cavity and a plurality of branch flow channels are formed in the first water passage of the utility model; the water tank and water seal can be replenished with water in the power-on and power-off states through the plurality of branch flow channels. In the power-off state, the branch flow channels are flushed in sequence to ensure the potential energy of each branch flow channel, that is, the potential energy flushing of the brush circle water channel, the flushing of the main water channel, and the delayed replenishment of the water tank when the main water channel is flushing.

[0023] (4) The utility model comprises the mechanical switching assembly including a first switch group, a second switch group, a time-delay switch group, a switching drive group and the water distribution part. The overall structural design is very ingenious. When the first switch group is replenished with water by the action of the first float, the other parts do not move (when powered on); when the power is off, only the switching drive group acts on the first switch group, and the time-delay switch group and the second switch group are linked to switch the first and second water outlets. At the same time, when the second water outlet is flushing, the first water outlet is delayed to open, that is, the water replenishment is delayed, so that the second water outlet has enough time to be filled with water and flushed.

[0024] (5) The extended switch group described in the utility model acts on the second switch group in the form of a counterweight cup combined with a float bucket seat, so that when the second water outlet is opened by the second switch group, the water in the counterweight cup continues to flow into the float bucket seat, so that the first float of the float bucket seat has buoyancy, and the first switch group will not be opened for water replenishment. In this way, the second switch group can have a longer water injection time, that is, a longer amount of water for flushing. More importantly, the second switch group can be directly connected to the water inlet pipe without the need to distribute the water stored in the water tank. In this way, the first water outlet exclusively uses the water stored in the water tank, and the amount of water used for flushing is sufficient, and the flushing effect is better.

[0025] (6) The switching drive group described in the utility model is composed of a sliding part, a rocker arm, a torsion spring, and a connecting part. It has a simple structure and can realize multi-component linkage control. After the connecting part is driven, the sliding part moves linearly along the axial direction of the main body, and at the same time acts on one end of the rocker arm to make the rocker arm swing. While swinging, the water diversion part also rotates to switch different diversion channels; after the connecting part is loosened, the rocker arm is driven to reset through the torsion spring; this switching drive group drives the sliding part and the rocker arm to simultaneously open the first switch group and switch the water diversion part through a connecting part, and close the second switch group, realizing a one-object-multi-link structure that is ingenious, easy to prepare, easy to assemble, and not prone to failure.

[0026] In addition, the utility model also presses against the counterweight cup at one end of the rocker arm away from the sliding member when the first switch group is turned on, so as to limit the counterweight cup from falling and turning on the second switch group; in this way, when the sliding member drives the rocker arm to switch, that is, when the branch channel of the jet is opened, the second switch group is ensured to be in the closed state, which plays a double restriction role and ensures the reliability and strong potential energy of each individual flushing.

[0027] (7) The utility model also installs a one-way valve on the water outlet, the connecting pipe or the connection between the connecting pipe and the water outlet to limit the water flow of the water outlet from entering the connecting pipe. This ensures that when the water pump is pumping water for flushing under power, the water flow will not be introduced from the water outlet into the connecting pipe, thereby avoiding the reduction of flushing potential energy due to diversion.

[0045] like Figure 1 As shown, the multifunctional valve group for realizing water inlet and non-electric flushing of the toilet described in this embodiment is used for flushing of the intelligent toilet, that is, for flushing the brush ring waterway, the main flushing waterway and the waterway forming the water seal of the toilet. Generally, the waterway of the water seal and the main flushing waterway are the same waterway;

[0046] like Figure 1 As shown, the multifunctional valve group includes a flushing assembly 1, a water inlet assembly 2 and a connecting pipe 6; the multifunctional valve group is installed in the water tank;

[0047] The flushing assembly 1 includes two water outlets 11 and 12 respectively corresponding to the water channel of the toilet brush ring and the main flushing water channel. The water in the water tank is pumped to each water outlet 11 and 12 through the pumping member 13; that is, the pumping member 13 fixes the bottom of the water tank, and after being powered on, the water in the water tank is pumped to the brush ring water channel and the main flushing water channel for flushing; this is the flushing process of the smart toilet.

[0048] In this embodiment, the water inlet assembly 2 is used to replenish the water tank and to inject water into the two water outlets 11 and 12 through the connecting pipe 6 in the power-off state;

[0049] like Figure 1 , 2 As shown, the water inlet assembly 2 includes a main body 21, a water inlet pipe 22, a first buoy 23, a mechanical switching assembly 3, a first switch group 31, a second switch group 32, a delay switch group 33, a switching drive group 34, a water distribution member 35, a rocker rod 341, a torsion spring 342, a connecting member 343, a sliding member 344 and a one-way valve (not shown in the figure);

[0050] The main body 21 is provided with a water inlet chamber 211 and a first water pass portion 212 and a second water pass portion 213 communicating with the water inlet chamber 211. The first water pass portion 212 and the second water pass portion 213 are opened and closed by the first switch group 31 and the second switch group 32 respectively to achieve communication with the water inlet chamber 211. The water inlet chamber 211 is connected to the water inlet pipe 22. It should be noted that the water inlet pipe 22 in this embodiment is externally connected to a municipal water pipe (i.e., a tap water pipe);

[0051] During installation, the water inlet pipe 22 is mounted (threadedly connected) on the main body 21 and connected to the water inlet chamber 211, and the first and second water flow parts 212 and 213 are switched on respectively by the first switch group 31 and the second switch group 32 of the mechanical switching assembly 3; that is, when the first switch group 31 is turned on, the water of the water inlet pipe 22 can flow into the first water flow part 212, and the second switch group 32 is in a blocked and closed state; conversely, when the second switch group 32 is turned on, the water of the water inlet pipe 22 can flow into the second water flow part 213, and the first switch group 31 is in a blocked and closed state;

[0052] The first and second water-passing parts 212 and 213 are respectively connected to the two connecting pipes 6, and the first water-passing part 212 is configured to replenish water in the water tank and form a jet to inject into the connecting pipe 6 (the jet injection here refers to the pressurization of the water flow and ejection, which is achieved by changing the water-passing area of ​​the mouth in this embodiment, and of course it can also be other ways, such as air pressurization, etc. In this embodiment, the water flow with a large water-passing area is reduced through the small mouth to achieve a jet by reducing the outlet water-passing area), so that the water in the water tank is sucked into the connecting pipe 6 (this connecting pipe 6 is correspondingly connected to one of the water outlets 11 and 12, and this embodiment takes the water outlets 11 and 12 connected to the brush ring water channel as an example); the second water-passing part 213 is used to conduct the other connecting pipe 6 (that is, connected to the water outlets 11 and 12 for the main flushing water channel);

[0053] It should be noted that in order to increase the water level from the water inlet pipe 22 to the connecting pipe 6, the water inlet end of the connecting pipe 6 corresponding to the first water pass 212 is set lower than the water inlet chamber 211, thereby forming a height difference, which further increases the water level of the original municipal water pipe during the water inlet process.

[0054] In this embodiment, (such as Figure 3 , 4 As shown in the figure, the first water flow portion 212 is implemented with an independent shell, which is connected to the main body 21; a water flow cavity 212A and a plurality of branch channels A, B, C, and D are formed in the first water flow portion 212. In this embodiment, four branch channels are used as an example; at least one branch channel is configured as a branch channel A for water tank replenishment, which directly guides water flow into the water tank; at least one branch channel is configured as a branch channel B for forming a water seal of the toilet; at least one branch channel is configured as a branch channel C for forming the jet; at least one branch channel is configured to delay the opening of the first water flow portion 213 when water is discharged. An auxiliary diversion channel D of a water passing portion 212; wherein the water diversion member 35 of the mechanical switching assembly 3 is built into the water passing chamber 212A, and switches to block the diversion channels A, B, C, and D; in the present embodiment, the two diversion channels are arranged as a group, that is, the water diversion member 35 switches and rotates once, correspondingly blocking or opening the two diversion channels, wherein the diversion channel A for water tank replenishment and the diversion channel B for toilet water seal are arranged as a group, and the auxiliary diversion channel D and the diversion channel C for jet are allocated as a group, that is, switching once and opening the two diversion channels at the same time, so that the setting reduces the number of switching times and is easier to operate.

[0055] The mechanical switching assembly 3 includes a first switch group 31, a second switch group 32, a delay switch group 33, a switching drive group 34 and the water distribution member 35;

[0056] (like Figure 5As shown in the figure, the first switch group 31 is used to open and close the first water flow section 212, and is directly or indirectly connected to the first buoy 5; the first switch group 31 includes a first blocking member 311 and a first connecting rod 312; the first blocking member 311 is arranged corresponding to the water inlet chamber 211, and is used to block or communicate the water inlet chamber 211 with the first water flow section 212; it should be noted that the water inlet chamber 211 is separated from the water flow section by a partition wall, the water inlet chamber 211 is located at the center, and the first blocking member 311 is used to block the hole E at the center, That is, it can block the water flow from entering the first water pass part 212. This method reduces the operating force and has better stability. In addition, the first connecting rod 312 and the first blocking piece 311 are hinged and form a lever swing with the main body 21. In this way, when the first buoy 5 floats up and down with the water flow, the lever swing drives the first blocking piece 311 on the first connecting rod 312 to open and close. Not only can the first buoy 5 drive the first switch group 31 to operate, but the switching drive group 34 can also drive the first connecting rod 312 to operate (that is, in the power-off state, it is driven manually).

[0057] The second switch group 32 opens and closes the second water flow section 213 through the action of the delay switch group 33; the second switch group 32 includes a second blocking member 321, a second connecting rod 322 and a supporting elastic member 323. The second blocking member 321 and the second connecting rod 322 are respectively arranged in the same manner as the first blocking member 311 and the second connecting rod 322, and the description is not repeated here. The second blocking member 321 is arranged corresponding to the water inlet chamber 211, and is used for blocking or connecting the water inlet chamber 211 with the second water flow section 213; one end of the second connecting rod 322 is equipped with the second blocking member 321, and the other end is lever-shapedly swung by the action of the delay switch group 33; the supporting elastic member 323 is located below the second connecting rod 322, and acts on the second connecting rod 322 with elastic force.

[0058] The switching drive group 34 acts on the first switch group 31, the water distribution member 35 and the delay switch group 33;

[0059] In the powered state, when the first switch group 31 is opened by the first float 5, the water inlet pipe 22 conducts the water tank replenishment diversion channel A and / or the diversion channel B of the toilet water seal; in the de-powered state, when the first switch group 31 is opened by the switching drive group 34, the linkage water diversion component 35 opens the diversion channel C and the auxiliary diversion channel D for forming the jet, and blocks the water tank replenishment diversion channel and the diversion channels A and B of the toilet water seal.

[0060] like Figure 6 , 7 As shown, the time delay switch group 33 in this embodiment includes a weight cup 331 and a floating bucket seat 332;

[0061] The weight cup 331 is slidably mounted on the side of the main body 21 and is movably connected to the second switch group 32 (the movably connected here is in the form of a hook); the float seat 332 is mounted on the side of the main body 21 and is provided for the first buoy 5 to be mounted, so that the first buoy 5 can move in the float seat 332; a through hole 332A for connecting to the water tank is opened at the bottom of the float seat 332; when the water tank is replenished with water, the first buoy 5 is lifted up through the through hole 332A;

[0062] The weight cup 331 is located above the float seat 332 and has a channel 331A for guiding the water flow therein into the float seat 332; the water flow area of ​​the auxiliary diversion channel D is larger than the water flow area of ​​the channel 331A; thus, it is ensured that the water flow can be stored in the weight cup 331 to be pressed against the second connecting rod 322 later; it should be noted that the gravity of the weight cup 331 is smaller than the elastic force of the supporting elastic member 323, and the weight cup 331 cannot open the second water flow portion 213 when there is little water or no water inside;

[0063] Among them, the water flow of the auxiliary diversion channel D is injected into the counterweight cup 331, and the weight of the counterweight cup 331 and the water flow is greater than the supporting force of the supporting elastic member 323, so that the second blocking member 321 at the other end of the second connecting rod 322 opens the second water passing part 213; and after the water flow of the counterweight cup 331 is introduced into the float bucket seat 332, the first float 5 is delayed by the buoyancy to drive the first switch group 31 to open.

[0064] like Figure 8 As shown, the switching drive group 34 includes a rocker rod 341, a torsion spring 342, a connecting member 343 and a sliding member 344;

[0065] The swing rod 341 is connected to the water diverter 35 via the connecting shaft 345. That is, the swing rod 341 and the water diverter 35 are respectively arranged at the two ends of the connecting shaft 345 and are matched in a non-rotatable manner. That is, when the swing rod 341 swings, the water diverter 35 rotates accordingly. In addition, the swing rod 341 is matched with the sliding member 344.

[0066] The sliding member 344 is limitedly installed on the side of the main body 21, and extends a toggle block 344A and a limit block 344B; the toggle block 344A acts on the first connecting rod 312 to open and close the first blocking member 311; the limit block 344B cooperates with one end of the swing rod 341 to drive the swing rod 341 to swing circumferentially; one end of the connecting member 343 is attached to the sliding member 344, and the other end is installed outside to drive the swing rod 341 to swing. In this embodiment, the The connecting member 343 is a pull rope, one end of which is clamped on the sliding member 344, and the other end is connected to a button on the toilet (not shown in the figure). The connecting member 343 (pull rope) is pulled by pressing to drive the sliding member 344 to move; and the torsion spring 342 is installed on the connecting shaft 345, one end of which acts on the rocker arm 341, and the other end is clamped on the main body 21, so that when the sliding member 344 is acted upon, the rocker arm 341 is reset by the force of the torsion spring 342.

[0067] In addition, one end of the swing rod 341 away from the sliding member 344 abuts against the counterweight cup 331 when the first switch group 31 is turned on, so as to limit the counterweight cup 331 from falling and turn on the second switch group 32 .

[0068] In actual use:

[0069] (1) The multifunctional valve assembly described in this embodiment can simultaneously satisfy the use of the intelligent toilet in a power-off state and in a power-off state, and can maintain sufficient flushing potential energy and the form of flushing each flushing waterway in sequence in the power-off state, with sufficient flushing water volume and strong water flushing potential energy;

[0070] (2) In the power-on state (such as Fig. 9 As shown), the water inlet assembly 2 is used as a conventional water inlet valve. When the water in the water tank is at a low water level, the first buoy 5 is in a falling state. At this time, the first blocking member 311 is opened by the first connecting rod 312 connected to the first buoy 5, and the water flow of the water inlet pipe 22 enters the first water passing portion 212 through the water inlet chamber 211 and flows into the water passing chamber 212A. At this time, the water dividing member 35 in the water passing chamber 212A blocks the diverter channel C and the auxiliary diverter channel D to form a jet. The diverter channel A for water tank replenishment and the diverter channel B for water seal replenishment are normally open. Water flows from the diverter channel A for water tank replenishment to the water tank to realize water tank replenishment; during the water replenishment process, a water seal is formed for the water replenishment of the toilet bowl; after the water tank is replenished, the first buoy 5 floats up as the water level rises, driving the first blocking member 311 on the first connecting rod 312 to close;

[0071] Then, after the water pump is energized, the water flow is pumped to the brush circle water channel for flushing or the main flushing water channel for pumping. Due to the action of the water pump 13, the potential energy is increased, so there is no need to consider the problem of flushing potential energy when there is electricity; in addition, a one-way valve (not shown in the figure) is installed at the connection between the water outlet 11, 12, the connecting pipe 6 or the connecting pipe 6 and the water outlet 11, 12 to limit the water flow of the water outlet 11, 12 from entering the corresponding connecting pipes 6.

[0072] (3) When a power outage occurs (such as Figure 10-11 As shown), the water pump 13 cannot complete the flushing work normally at this time, and manual flushing can be performed through the mechanical switching component 3, as follows:

[0073] First, by pressing the button on the toilet, the connecting member 343 (i.e., the pull rope) is pulled, and the sliding member 344 at the other end of the connecting member 343 is pulled downward. At this time, while the sliding member 344 moves downward, its upper limit block 344B links the swing rod 341 to swing a certain angle (90 degrees in this embodiment). When the swing rod 341 swings, the connecting shaft 345 connected thereto rotates, and at the same time drives the water distribution member 35 to rotate and switch to block the water tank replenishment diversion channel A that was originally opened and the water seal of the toilet. The flow channel B opens the flow channel C and the auxiliary flow channel D to form a jet; it should be noted that when the sliding member 344 moves, the upper toggle block 344A moves downward at the same time, pressing down the second connecting rod 322 mounted on the toggle block 344A, and then opening the first water passing portion 212 when the first buoy 5 moves downward, that is, the blocking member 311 is opened; the water flows from the water inlet pipe 22 into the first water passing portion 212, and flows out from the flow channel C to form a jet and the auxiliary flow channel D;

[0074] Before the water flows out of the branch channel C that forms the jet, it first changes from a large diameter to a small diameter to increase its ejection potential energy. At the same time, because the height of the water inlet chamber 211 is higher than the outlet of the branch channel C of the jet, the ejected water has a stronger potential energy under the potential energy of the height difference. After forming the jet, it is injected into the center of the connecting pipe 6. At this time, because the inlet of the connecting pipe 6 is located below the water level of the water tank and is in a static state, a certain potential energy is formed by the jet water (i.e., a Venturi phenomenon is formed). At this time, the water in the water tank can be quickly sucked into the connecting pipe 6, and the connecting pipe 6 is connected to the brush ring water channel to achieve flushing of the brush ring water channel. It should be noted that the second water passing part 213 is in a blocked state at this time, and the water stored in the water tank is only used for flushing the brush ring water channel. Such a large amount of water and potential energy ensure the flushing of the brush ring water.

[0075] It should be noted that after the swing rod 341 rotates, the end thereof away from the sliding member 344 acts on the counterweight cup 331, restricting the counterweight cup 331 from falling and opening the second water passing portion 213. In this way, even if the water flow of the auxiliary flow channel D is poured into the counterweight cup 331 and exceeds the elastic force of the supporting elastic member 323, the second water passing portion 213 will not be opened, thus playing a double limiting role, thereby preventing the second water passing portion 213 from being opened before the first water passing portion 212 is flushed, thereby failing to achieve the flushing effect.

[0076] (3) After the brush ring water channel is flushed (i.e., the water in the water tank is sucked away), the first buoy 5 should fall down, but because the water in the weight cup 331 is introduced into the buoy seat 332 through the channel 331A, the first buoy 5 does not fall down under the continuous water supply;

[0077] Then, the button is released, the sliding member 344 loses the pulling force and moves downward, and at the same time, the sliding member 344 and the swing rod 341 are driven to reset by the force of the torsion spring 342. At this time, the water diverter 35 is also switched to the water tank water replenishment diverter A and the water seal diverter B of the toilet bowl; and the first connecting rod 312 is not affected by the sliding member 344, and the first buoy 5 does not fall, and the first connecting rod 312 quickly drives the first blocking member 311 to block;

[0078] At this time, the weight cup 331 is filled with water, and the overall weight is greater than the elastic force of the supporting elastic member 323, and the weight cup 331 loses the restriction of the swing rod 341, and moves downward quickly, thereby driving the second connecting rod 322 to move and open the second blocking member 321; at this time, the water flows out from the second water flow portion 213 corresponding to the second blocking member 321, and turns into the corresponding connecting pipe 6, and then the connecting pipe 6 guides the water into the water outlet 12 corresponding to the main flushing water channel to achieve flushing of the main flushing water channel; it should be noted that after the second blocking member 321 is opened, the water in the water inlet pipe 22 has the water pressure of municipal water, and the water volume is continuous, which is sufficient for the main flushing of waste;

[0079] During this process, the water in the weight cup 331 is continuously discharged into the float seat 332 through the channel 331A, and the bottom of the float seat 332 has a through hole 332A, and the water flow of the float seat 332 is discharged into the water tank until the water in the weight cup 331 is discharged, until the gravity of the two (water flow and the weight cup 331) is less than the force of the supporting elastic member 323, and then the second connecting rod 322 is driven to swing again, and the second blocking member 321 is linked to block the second water passing part 213; at this time, the water flow of the float seat 332 is discharged and then falls, and the first blocking member 311 is opened again through the first connecting rod 312, and the water flow of the water inlet pipe 22 is introduced into the water tank from the first water passing part 212, until the water in the water tank drives the first buoy 23 to move up, and finally the water inlet is closed;

[0080] Through the action of the counterweight cup 331 and the float seat 332, the first float 5 is supported by the water flow of the float seat 332 when the water tank is drained, thereby delaying the opening of the first water flow section 212, giving the second water flow section 213 enough time to flush water. Moreover, water is continuously introduced directly from the municipal water pipe during flushing, and there is sufficient water volume, so there is no need to wait for the water tank to be refilled before flushing.

[0081] The above specification and description of the embodiments are used to explain the protection scope of the utility model, but do not constitute a limitation on the protection scope of the utility model.
