Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a noise reduction structure for a toilet and a toilet. Background Technology

[0002] In toilet design, the brush ring hole is a key structure for achieving inner wall cleaning and pretreatment: during the flushing stage, it sprays water to remove dirt, and during the pre-wetting stage, it sprays a small amount of water to wet the inner wall to reduce dirt adhesion. These two functions directly affect the toilet's cleaning efficiency and user experience.

[0003] However, in existing technologies, after rinsing or pre-wetting, a small amount of water tends to remain in the channels and outlets of the brush ring holes. Water in the water path falls from the highest point to both sides due to gravity, creating a vacuum. When air enters through the brush ring holes, it enters the water outlet channel, while water at the rear of the pipe flows out through the brush ring holes. As the air bubbles entering through the brush ring holes pass through the water in the pipe and reach the highest point, the gas and water mix violently, forming intermittent bubbles that burst, producing a noticeable "gurgling" noise.

[0004] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a noise reduction structure for a toilet that can prevent "gurgling" noise after flushing or pre-wetting.

[0006] Another objective of this utility model is to provide a toilet.

[0007] To achieve the above objectives, the present invention adopts the following solution: A noise reduction structure for a toilet includes: a control valve, a flushing water path, and a switching valve assembly. The control valve controls the opening and closing of the inlet water path. The flushing water path has an inlet water path, a first outlet water path, and a second outlet water path. The switching valve assembly selectively switches between the inlet water path and both the first and second outlet water paths, or between the inlet water path and either the first or second outlet water path. After flushing or pre-wetting the toilet, the control valve closes, allowing the inlet water path to connect with both the first and second outlet water paths.

[0008] In some embodiments, the top of the water inlet passage forms a downward-bending bend.

[0009] In some embodiments, during toilet flushing, the control valve opens, and the water inlet path is connected to the first water outlet path or the second water outlet path; or, the water inlet path can be connected to both the first water outlet path and the second water outlet path.

[0010] In some embodiments, during the toilet pre-wetting process, the control valve is opened, and the water inlet path is connected to the first water outlet path or the second water outlet path.

[0011] In some embodiments, after the toilet flushing or pre-wetting is completed, the control valve closes, and the inlet water path can be connected to both the first and second outlet water paths to complete the air intake operation, allowing air to enter one of the first and second outlet water paths, and water to flow out from the other of the first and second outlet water paths; after the air intake operation is completed, the switching component can switch the state in which the inlet water path is connected to both the first and second outlet water paths to the state in which the inlet water path is connected to either the first or second outlet water path, or the switching valve component can not switch after the air intake operation is completed.

[0012] In some embodiments, the control valve is a water pump or a solenoid valve; the inlet end of the water inlet circuit is sealed and connected to a water tank or a municipal water supply terminal.

[0013] In some embodiments, the switching valve assembly includes a control motor, a switching chamber, and a switching plate. The control motor controls the switching plate to move within the switching chamber, so that the inlet water path is connected to both the first outlet water path and the second outlet water path, or the inlet water path is connected to either the first outlet water path or the second outlet water path.

[0014] In some embodiments, when the inlet water path is connected to both the first outlet water path and the second outlet water path, the switching plate fully opens the first outlet water path and the second outlet water path; or, the switching plate partially blocks the inlet end of the first outlet water path or the inlet end of the second outlet water path.

[0015] In some embodiments, the switching valve assembly further includes a connector housing having a first connector, a second connector and a third connector, wherein the first connector is sealed to the inlet water passage, the second connector is sealed to the first outlet water passage, and the third connector is sealed to the second outlet water passage.

[0016] A toilet includes a toilet body and a noise reduction structure installed on the toilet body. A first water outlet is connected to the toilet's brush ring water outlet, and a second water outlet is connected to the toilet's main flush water outlet. When the toilet is flushed, water is discharged from the brush ring water outlet and / or the main flush water outlet. When the toilet is pre-wetting, water is discharged only from the brush ring water outlet.

[0017] As can be seen from the above technical solution, this utility model, through the coordinated structural design of the control valve, flushing water path, and switching valve assembly, allows the switching valve assembly to switch to a state where the inlet water path is connected to the first and second outlet water paths, or the inlet water path is connected to the first / second outlet water path, when the toilet is in the flushing or pre-wetting stage, to satisfy the cleaning and / or pre-wetting functions. After the toilet is flushed or pre-wetting is completed, the water in the inlet water path falls under the action of gravity, forming a vacuum negative pressure to perform air suction. The inlet water path is connected to the first and second outlet water paths, achieving a dual-outlet water path connection state. This allows the water to flow away from the second outlet water path when air enters the first outlet water path, dispersing the residual water flow and quickly discharging the water in the pipe. This reduces the rapid intake of external air, reducing the gas-liquid mixing disturbance, and simultaneously balances the air pressure in the pipe, preventing air bubbles from bursting and airflow from impacting the inner wall of the pipe. This avoids the "gurgling" noise after the toilet is flushed or pre-wetting is completed. Attached Figure Description

These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0027] Reference Figures 1 to 5 As shown, this utility model discloses a noise reduction structure, including: a control valve 1, a flushing water path 2, and a switching valve assembly 3. The control valve 1 controls the opening and closing of the inlet water path 21. The flushing water path 2 has an inlet water path 21, a first outlet water path 22, and a second outlet water path 23. The switching valve assembly 3 selectively switches so that the inlet water path 21 is connected to both the first outlet water path 22 and the second outlet water path 23, or so that the inlet water path 21 is connected to either the first outlet water path 22 or the second outlet water path 23. After the toilet is flushed or pre-wetted, the inlet water path 21 can be connected to both the first outlet water path 22 and the second outlet water path 23. Specifically, after the control valve 1 is closed, the switching valve assembly 3 switches to a state where the inlet water passage 21 is connected to the first outlet water passage 22 and the second outlet water passage 23; in other embodiments, the switching valve assembly 3 can also switch to a state where the inlet water passage 21 is connected to the first outlet water passage 22 and the second outlet water passage 23 before the control valve 1 is closed; in the embodiment shown in the figure, the first outlet water passage 22 is used for brush ring water outlet and the second outlet water passage 23 is used for main flush water outlet as an example.

[0028] Therefore, this utility model, through the coordinated structural design of the control valve 1, flushing water path 2, and switching valve assembly 3, ensures that when the toilet is in the flushing or pre-wetting stage, the control valve 1 opens, and the switching valve assembly 3 switches to a state where the inlet water path 21 and the first outlet water path 22 and the second outlet water path 23 are all connected, or the inlet water path 21 and the first outlet water path 22 or the second outlet water path 23 are connected, thus satisfying the cleaning and / or pre-wetting functions. Specifically, during the toilet flushing process, the control valve 1 opens, and the toilet sequentially dispenses water from the brush ring, then from both the brush ring and the main flush simultaneously, and then from the brush ring again to replenish the toilet bowl water seal. In other embodiments, the toilet may sequentially dispense water from the brush ring, then from the main flush, and then from the brush ring again to replenish the toilet bowl water seal, thereby improving flushing efficiency.

[0029] During the toilet pre-wetting process, the control valve 1 is opened, and water is only discharged from the toilet brush ring to lubricate the toilet bowl porcelain. The water inlet 21 is connected to the first water outlet 22 or the second water outlet 23.

[0030] During toilet flushing, the control valve 1 is opened, and the water inlet channel 21 is connected to the first water outlet channel 22 or the second water outlet channel 23; or, the water inlet channel 21 can be connected to both the first water outlet channel 22 and the second water outlet channel 23.

[0031] After the toilet flushing or pre-wetting is complete, the control valve 1 closes, allowing the inlet water passage 21 to connect with both the first outlet water passage 22 and the second outlet water passage 23 to complete the air intake operation. This allows air to enter one of the first outlet water passage 22 and the second outlet water passage 23, while water flows out from the other. After the air intake operation is complete, the switching component 3 can switch the state where the inlet water passage 21 is connected to both the first outlet water passage 22 and the second outlet water passage 23 to a state where the inlet water passage 21 is connected to either the first outlet water passage 22 or the second outlet water passage 23. Alternatively, after the air intake operation is complete, the switching valve... Component 3 does not switch; as the water in the inlet water passage 21 falls under the action of gravity, it forms a vacuum negative pressure, thereby performing an air intake function. The switching valve component 3 switches to connect the inlet water passage 21 with the first outlet water passage 22 and the second outlet water passage 23, achieving a dual outlet water passage connection state. When air enters the first outlet water passage 22, the water flows away from the second outlet water passage 23, dispersing the residual water flow and quickly discharging the water in the pipe. This reduces the rapid intake of external air, which forms gas-liquid mixing disturbance. At the same time, it balances the air pressure in the pipe, preventing air bubbles from bursting and airflow from impacting the inner wall of the pipe. This can avoid the "gurgling" noise after the toilet flushing or pre-wetting is completed.

[0032] In some embodiments, the top of the water inlet passage 21 forms a downward-bending pipe section 211; when the control valve 1 is closed, the switching valve assembly 3 switches to connect the water inlet passage 21 with the first water outlet passage 22 and the second water outlet passage 23. The pipe section 211 can block the rapid influx of air, buffer water pressure fluctuations, reduce gas-liquid mixing disturbances, further suppress the generation of "gurgling" noise, and enhance the noise reduction effect.

[0033] The water inlet end of the water inlet channel 21 is sealed and connected to the water tank 4, but this is not a limitation. The water inlet end of the water inlet channel 21 can also be sealed and connected to the municipal water supply end.

[0034] In some embodiments, the control valve 1 is a water pump or a solenoid valve; in the embodiment shown in the figure, the control valve 1 is a water pump.

[0035] In some embodiments, the switching valve assembly 3 includes a control motor 32, a switching chamber 33, and a switching plate 34. The control motor 32 controls the switching plate 34 to move within the switching chamber 33, so that the inlet water passage 21 is connected to the first outlet water passage 22 and the second outlet water passage 23, or the inlet water passage 21 is connected to the first outlet water passage 22 / second outlet water passage 23.

[0036] Furthermore, when the inlet water passage 21 and the first outlet water passage 22 and the second outlet water passage 23 are all connected, the switching plate 34 fully opens the first outlet water passage 22 and the second outlet water passage 23, as follows: Figure 3 As shown; or, the switching piece 34 partially blocks the inlet end of the first water outlet channel 22 or the inlet end of the second water outlet channel 23.

[0037] Furthermore, to facilitate the connection of the inlet water passage 21, the first outlet water passage 22, and the second outlet water passage 23, the switching valve assembly 3 also includes a connector housing 31. The connector housing 31 has a first connector 311, a second connector 312, and a third connector 313. The inner cavity of the connector housing 31 forms the switching cavity. The first connector 311 is sealed to the inlet water passage 21, the second connector 312 is sealed to the first outlet water passage 22, and the third connector 313 is sealed to the second outlet water passage 23.

[0038] Please see Figure 5 As shown, the switching valve assembly 3 also includes a cavity sealing cover 35, which seals and covers the switching cavity 33. The switching plate 34 is housed in the switching cavity 33. The motor shaft of the control motor 32 passes through the cavity sealing cover 35 and is connected and fixed to the switching plate 34, so that the control motor 32 controls the movement of the switching plate 34.

[0039] Furthermore, the switching valve assembly also includes a mounting base 36, a motor bracket 37, and a motor sealing cover 38. The mounting base 36 is detachably fixed to the cavity sealing cover 35. The control motor 32 is detachably fixed to the motor bracket 37. The motor bracket 38 is detachably fixed to the side of the mounting base 36 facing away from the cavity sealing cover 35. The motor sealing cover 38 is detachably fixed to the side of the mounting base 36 facing away from the cavity sealing cover 35. A chamber is formed between the motor sealing cover 38 and the mounting base 36. The control motor 32 and the motor bracket 37 are installed in the chamber.

[0040] This utility model also discloses a toilet, including a toilet body and a noise reduction structure of this utility model installed on the toilet body. The first water outlet 22 is connected to the toilet brush ring water outlet, and the second water outlet 23 is connected to the toilet main flushing water outlet. When the toilet is flushed, water is discharged from the brush ring water outlet and / or the main flushing water outlet. When the toilet is pre-wetting, only the brush ring water outlet is discharged.

[0041] Please see Figures 2 to 4 As shown, when the toilet flushing / pre-wetting of this invention ends and the water level remains at the brush ring outlet, the inlet water passage 21 and the first outlet water passage 22 are filled with water, while the second outlet water passage 23 is not discharging water. After the toilet flushing of this invention is completed, the switching valve assembly 3 switches to connect the inlet water passage 21, the first outlet water passage 22, and the second outlet water passage 23. Air enters the first outlet water passage 22 through the hole in the brush ring, and water falls from the highest point to both sides of the bend section 211 of the inlet water passage 21. The water will quickly flow out from the second outlet water passage 23, thereby reducing the mixing and disturbance of air bubbles and water entering through the hole in the brush ring and avoiding the "gurgling" sound. After the air intake of the brush ring is completed, the control motor will drive the switching plate to return to the initial position, that is, the inlet water passage 21 is connected to the first outlet water passage 22. Of course, in other embodiments, the switching plate may not switch to the initial position after the air intake of the brush ring is completed.

The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and this invention is not limited to any specific details of these embodiments.
