Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a toilet sewage discharge device and a toilet. Background Technology

[0002] Most existing toilets use a brush ring to spray water to clean the toilet bowl, and then the wastewater is discharged through the drain pipe. After the wastewater is discharged, the brush ring will continue to spray water to create a water seal on the toilet bowl.

[0003] The toilet bowl and drain pipe are sealed together by a sealant. As the toilet is used over time, the sealant’s effectiveness decreases, leading to slow leakage and weakening the toilet’s water seal function.

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

[0005] The main purpose of this utility model is to provide a toilet flushing device that can maintain the water seal function of the toilet when the sealing effect is reduced.

[0006] The secondary objective of this utility model is to provide a toilet that utilizes the toilet drainage device of this utility model.

[0007] To achieve the above objectives, the present invention adopts the following solution:

[0008] A toilet flushing device includes: a toilet bowl and a flushing mechanism. The flushing mechanism includes a flushing tray and a flushing box. The water inlet of the flushing tray is connected to the drain outlet of the toilet bowl and is rotatable relative to the flushing box. The flushing tray can switch between an initial state and a flushing state. In the initial state, the toilet bowl has a water seal. In the flushing state, water from the toilet bowl can be discharged from the flushing tray. The device also includes a water replenishment mechanism that replenishes water to the toilet bowl and / or the flushing tray.

[0009] Furthermore, a toilet flushing device also includes a control module and a drive module. The drive module is used to drive the flushing tray. The control module is connected to the drive module and the water replenishment device respectively. When the control module detects that the flushing tray has not been driven to switch within a first preset time, and / or when the control module detects that the water replenishment device has not been driven to replenish water within the first preset time, the control module controls the water replenishment device to replenish water. The first preset time is greater than 1 hour.

[0010] Preferably, the first preset time is 24 hours.

[0011] Alternatively, a toilet flushing device may further include a control module and a liquid level sensor. The control module is connected to both the liquid level sensor and the water replenishment device. The liquid level sensor can detect changes in the liquid level inside the toilet bowl. When the liquid level sensor detects that the liquid level inside the toilet bowl has dropped to a first preset value, the liquid level sensor sends a feedback signal to the control module. The control module then controls the water replenishment device to replenish water to the toilet bowl. The first preset value is greater than 5 mm.

[0012] Preferably, the first preset value is 30mm.

[0013] Furthermore, the water replenishment device includes a flushing water path connected to a municipal water supply pipe or a water tank; the flushing water path also includes a brush control valve, which is any one of a solenoid valve, a reversing valve, a water pump, or a mechanical inlet valve. The control valve controls the on / off state of the flushing water path, including a main flushing water path or a brush ring water path. The main flushing water path is used to flush the bottom of the toilet, and the brush ring water path is used to flush the toilet bowl surface.

[0014] Furthermore, the water replenishment device also includes a water replenishment head installed on the sewage discharge device. The outlet of the water replenishment head is directly opposite the water outlet of the sewage discharge pan. The water replenishment head is connected to a municipal water supply pipe or water tank to form a water replenishment path. The water replenishment path is controlled by a control valve, which can be any one of a solenoid valve, a reversing valve, a water pump, or a mechanical inlet valve. When the water replenishment path supplies water, it can replenish water to the toilet bowl surface through the water replenishment head.

[0015] Furthermore, a sealing element is provided between the drain pan and the drain box body. The sealing element is a Y-shaped sealing ring, which is installed at the water inlet end of the drain pan.

[0016] Furthermore, an installation chamber is provided on one side of the toilet bowl, the sewage discharge device is installed in the installation chamber, and the water replenishment device is installed in the installation chamber, above the installation chamber, or at the toilet brush ring opening or the toilet main flush opening.

[0017] A toilet includes: a toilet body and the aforementioned toilet flushing device, wherein the toilet flushing device is installed in the toilet body.

[0018] As can be seen from the above technical solution, the present invention, through the structural design of the water replenishment device, enables the toilet to replenish water to the toilet bowl and / or the drain pan, thereby maintaining the water seal function of the toilet.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. 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.

[0040] Example 1: Refer to Figures 1-3 As shown, this utility model discloses a toilet flushing device, including: a toilet bowl 2 and a flushing device 5. The flushing device 5 includes a flushing tray 3 and a flushing box 33. The water inlet of the flushing tray 3 is connected to the drain outlet of the toilet bowl and can rotate relative to the flushing box 33. The flushing tray 3 can switch between an initial state and a flushing state. In the initial state, the toilet bowl 2 has a water seal. In the flushing state, water from the toilet bowl 2 can be discharged from the flushing tray 3. The device also includes a water replenishment device 7, which can replenish water to the toilet bowl 2 and / or the flushing tray 3.

[0041] Therefore, through the structural design of the water replenishment device 7, this utility model enables the toilet to replenish water to the toilet bowl 2 and / or the drain pan 3, thereby maintaining the water seal function of the toilet.

[0042] The toilet flushing device of this utility model also includes a control module and a drive module. The drive module is used to drive the flushing tray 3. The control module is connected to the drive module and the water replenishment device 7. When the control module detects that the flushing tray 3 has not been driven to switch within a first preset time, and / or when the control module detects that the water replenishment device 7 has not been driven to replenish water within the first preset time, the control module controls the water replenishment device 7 to replenish water to the toilet bowl 2. The first preset time is greater than 1 hour. Preferably, the first preset time is 24 hours. The 24-hour setting is to ensure that automatic water replenishment occurs at the same time the day after the last use, thereby minimizing the occurrence of water replenishment during sleep at night. The 24-hour setting also prevents excessive water seal leakage when the sealing element 32 leaks due to prolonged exposure.

[0043] Furthermore, the water replenishment device 7 includes a flushing water path, which is connected to a municipal water supply pipe or a water tank; the flushing water path also includes a control valve 4, which is any one of a solenoid valve, a reversing valve, a water pump, or a mechanical inlet valve; the flushing water path includes a main flushing water path or a brush ring water path, the main flushing water path is used to flush the bottom of the toilet, and the brush ring water path is used to flush the toilet bowl surface.

[0044] Furthermore, the water replenishment device 7 also includes a water replenishment head 72 disposed on the sewage discharge device 5. The outlet of the water replenishment head 72 is directly opposite the water outlet of the sewage discharge pan 3. The water replenishment head 72 is connected to the municipal water supply pipe or water tank to form a water replenishment path. The water replenishment path is controlled by a control valve. The control valve is any one of a solenoid valve, a reversing valve, a water pump, or a mechanical inlet valve. When the water replenishment path supplies water, the toilet bowl surface 2 can be replenished with water through the water replenishment head 72.

[0045] The control valve controls the opening and closing of the flushing water path. The control valve here can be the solenoid valve 4 on the flushing water path, or it can be a separate solenoid valve. The reversing valve can supply water to the water supply head 72, or it can supply water to the arm wash spray gun.

[0046] Furthermore, a sealing element 32 is provided between the drain pan 3 and the drain box 33. The sealing element 32 is a Y-shaped sealing ring, which is installed at the water inlet end of the drain pan 3.

[0047] Furthermore, an installation chamber 8 is provided on one side of the toilet bowl 2, the sewage discharge device 5 is installed in the installation chamber 8, and the water replenishment device 7 is installed in the installation chamber 8, above the installation chamber 8, or at the toilet brush ring opening or the toilet main flush opening.

[0048] This utility model also discloses a toilet, including: a toilet body 1 and the above-mentioned toilet sewage discharge device 5, wherein the toilet sewage discharge device 5 is installed inside the toilet body 1.

[0049] The drive module can be a drive control device 6. The drain pan 3 can be controlled to rotate by the drive control device 6. The drain pan 3 has a water inlet end 31. The sealing element 32 is located outside the water inlet end 31. The drive control device 6 controls the drain pan 3 to rotate, so that the drain pan 3 can switch between the initial state and the draining state. The solenoid valve 4 controls the water replenishment device 7 to replenish water to the toilet bowl 2. Through the cooperation structure of the solenoid valve 4 and the water replenishment device 7, this utility model allows the water seal function of the toilet to be maintained when the sealing element 32 has been used for a long time and the sealing effect has decreased.

[0050] Next, the drive control device 6 may include a rotating shaft 61 and a drive assembly 62. The rotating shaft 61 is fixed to the drain pan 3, and the drive assembly 62 drives the rotating shaft 61 to rotate the drain pan 3.

[0051] Furthermore, to facilitate water replenishment, the water replenishment device 7 can use a brush ring nozzle 71 for water replenishment. The water replenishment device 7 includes a brush ring nozzle 71, and the solenoid valve 4 controls the brush ring nozzle 71 to replenish water to the toilet bowl surface 2. The solenoid valve 4 can be opened periodically (e.g., if the toilet has not been flushed for a day), so that the solenoid valve 4 controls the brush ring nozzle 71 to perform water seal replenishment.

[0052] In addition, to facilitate the introduction of external tap water for water replenishment, the water replenishment device 7 may also include a water replenishment head 72. The solenoid valve 4 also controls the water replenishment head 72 to replenish water to the toilet bowl 2. The water replenishment head 72 is connected to external tap water. The solenoid valve 4 can be opened periodically (e.g., if the toilet has not been flushed for a day), and the solenoid valve 4 controls the water replenishment head 72 to perform water seal replenishment.

[0053] Therefore, this utility model ensures the normal operation of the toilet's water seal odor-blocking function by periodically controlling the opening of the solenoid valve 4, allowing the solenoid valve 4 to control the brush ring nozzle 71 to replenish water for the water seal, or allowing the solenoid valve 4 to control the water replenishment head 72 to replenish water for the water seal. The structure is simple and the function is reliable.

[0054] Furthermore, for a compact overall structure, an installation chamber 8 is provided on one side of the toilet bowl 2. The drain pan 3, drive control device 6, and drain pipe 51 are installed in the installation chamber 8. The solenoid valve 4 and water replenishment device 7 are installed above the installation chamber 8, and the drain pipe 51 is located below the drain pan 3.

[0055] Preferably, to reduce the force required to drive the drain pan 3 to rotate, the sealing element 32 adopts a Y-shaped sealing ring; thereby, the drain pan 3 is driven to switch between the initial state (i.e., the toilet bowl 1 has a water seal) and the drain state (i.e., the water in the toilet bowl 1 can be discharged by the drain pan 3) to achieve the toilet's drain function, and a dynamic seal is formed between the drain pan 3, the toilet bowl 1, and the drain device 5.

[0056] Preferably, the sewage discharge device 5 further includes a sewage discharge pipe 51 and a sewage discharge buffer chamber 52. The sewage discharge buffer chamber 52 is located at the upper end of the sewage discharge pipe 51. The sewage discharge port is selectively connected to the sewage discharge buffer chamber 52. The sewage discharge buffer chamber 52 is connected to the sewage discharge pipe 51. Thus, the sewage discharge tray 3 is facilitated to discharge sewage through the setting of the sewage discharge buffer chamber 52.

[0057] Furthermore, the sewage pipe 51 includes a first sewage area 511 and a second sewage area 512. The connection between the first sewage area 511 and the second sewage area 512 is located on the side. The inlet of the first sewage area 511 is located at the top, and the outlet of the second sewage area 512 is located at the bottom, so as to facilitate the discharge of excrement from the sewage outlet on the ground.

[0058] Furthermore, the toilet bowl 2 is a sloping surface that slopes downwards, and the bottom surface of the drain pan 3 is a V-shaped sloping surface. Thus, when in the initial state, the toilet bowl 2 and the drain pan 3 form a U-shaped structure, which facilitates the formation of a water seal at the bottom of the toilet.

[0059] In summary, in the initial state of the toilet of this utility model, the drain pan 3 is in a vertically upward state. At this time, the toilet bowl 2 and the drain pan 3 form a U-shaped structure. The solenoid valve 4 is opened, controlling the brush ring nozzle 71 to spray out flushing water. It can also control the water replenishment head 72 to replenish water to the drain pan 3. The water entering the drain pan 3 will flow to the toilet bowl 2, and the water flow can gather at the bottom of the toilet (i.e., the toilet bowl 2) to form a water seal.

[0060] When the toilet performs the flushing procedure, the solenoid valve 4 is opened first, and the flushing water sprayed from the brush nozzle 71 continuously flushes the toilet bowl surface 2, washing the dirt on the toilet bowl surface 2 to the bottom of the toilet. The flushing water gathers at the bottom of the toilet, and after a certain period of time, the drive component 62 drives the drain plate 3 to rotate, so that the drain inlet 31 of the drain plate 3 is connected to the drain pipe 51. Under the action of gravity, the water gathered in the toilet is quickly discharged from the drain pipe 51 and carries away the dirt. During the process of discharging the dirt, the brush nozzle 71 continuously supplies water to continuously flush the toilet bowl surface 2.

[0061] After the flushing is complete, the drain pan 3 rotates back to its initial state under the drive assembly 62, and the brush nozzle 71 continues to supply water, reforming a water seal at the bottom of the toilet. Once the water seal is full, the solenoid valve 4 closes, and the flushing process is complete.

[0062] Example 2: The toilet flushing device 5 of this utility model may further include a control module and a liquid level sensor 9. The control module is connected to the liquid level sensor 9 and the water replenishment device 7 respectively. The liquid level sensor 9 can detect changes in the liquid level inside the toilet bowl 2. When the liquid level sensor 9 detects that the liquid level inside the toilet bowl 2 has dropped to a first preset value, the liquid level sensor 9 sends a feedback signal to the control module. The control module then controls the water replenishment device 7 to replenish water to the toilet bowl 2. The first preset value is greater than 5mm. Preferably, the first preset value is 30mm.

[0063] It should be understood that the various examples described above can be utilized in multiple directions, such as tilted, inverted, horizontal, vertical, etc., and in multiple configurations, without departing from the principles of this invention. 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.

[0064] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
