Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a water outlet device and its flushing system. Background Technology

[0002] In existing smart toilets, the Venturi effect is often used in the flushing technology to enhance water flow and cleaning effect. This Venturi effect significantly improves the cleaning efficiency of the toilet's wash surface and reduces residual dirt. Currently, smart toilets' Venturi flushing systems generally use one of two water supply methods: one directly utilizes the natural water pressure of municipal tap water, which is simple in structure and low in cost, but may lead to a decrease in flushing effect when the water pressure is insufficient; the other uses a submersible pump to actively boost water pressure, which can stably provide higher water pressure to ensure the full realization of the Venturi effect.

[0003] In view of this, the designer of this utility model developed this utility model, which combines water pressure and pump to optimize the flushing effect. Utility Model Content

[0004] The purpose of this invention is to provide a water outlet device and its flushing system that can guarantee the flushing effect.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A water outlet device includes: a flow booster pipe assembly and a flushing water path. The flow booster pipe assembly includes at least one first water inlet channel and at least one second water inlet channel. The first water inlet channel and the second water inlet channel are arranged relatively independently. The water flowing out of the first water inlet channel and the water flowing out of the second water inlet channel flow out through the flushing water path.

[0007] In some embodiments, the booster tube assembly is a Venturi effect booster tube assembly, which includes a booster tube, a first nozzle at the outlet end of the first inlet channel, a second nozzle at the outlet end of the second inlet channel, a gap between the first nozzle and the inlet end of the booster tube, a gap between the second nozzle and the inlet end of the booster tube, and the outlet end of the booster tube is connected to a flushing water path.

[0008] In some embodiments, the first nozzle and the second nozzle are arranged in parallel along the radial direction of the booster pipe, the diameter of the first nozzle is smaller than the diameter of the first water inlet channel, and the diameter of the second nozzle is smaller than the diameter of the second water inlet channel.

[0009] In some embodiments, a water outlet device further includes a valve body installed between a first water inlet channel and a second water inlet channel, the valve body controlling the opening and closing of the second water inlet channel.

[0010] In some embodiments, the second water inlet channel is provided with a valve port, and the valve body is also provided with a movable cavity and a movable component. The movable component can move within the movable cavity to cooperate with the opening and closing of the valve port. When water enters the first water inlet channel, part of the water flows to the movable cavity to drive the movable component to close the valve port, thereby closing the second water inlet channel. When water enters the second water inlet channel, the movable component opens the valve port, thereby opening the second water inlet channel.

[0011] In some embodiments, when the first water inlet channel and the second water inlet channel are filled with water at the same time, and the water pressure in the second water inlet channel is greater than the water pressure in the first water inlet channel, the movable component opens the valve port.

[0012] In some embodiments, the movable element includes a diaphragm, a pressure difference is formed on both sides of the diaphragm, and the diaphragm moves under the action of the pressure difference.

[0013] In some embodiments, the first water inlet channel is formed in the first pipe, the second water inlet channel is formed in the second pipe, the first pipe and the second pipe are arranged in parallel and connected, the portion where the first pipe and the second pipe are connected forms the movable cavity, the valve body is also provided with a water passage hole, the water passage hole connects the movable cavity and the first water inlet channel, and also includes a second water inlet connector, the second water inlet connector is installed at the water inlet end of the second water inlet channel, and the diaphragm is disposed between the second water inlet connector and the movable cavity.

[0014] In some embodiments, the first water inlet channel can be connected to tap water, and the second water inlet channel can be connected to pressurized tap water.

[0015] A flushing system includes the aforementioned water outlet device, and further includes an inlet valve, a first control valve, a second control valve, a water tank, and a pump. The first control valve controls the water flowing out of the inlet valve to enter a first inlet channel, and the second control valve controls the water flowing out of the inlet valve to enter the water tank. The pump is connected to the water tank and the second inlet channel respectively.

[0016] In some embodiments, a flushing system further includes a four-way connector, a flushing aid valve pipeline, a drain valve, a flushing aid water path, and a main flushing water path. The pump is connected between the inlet end of the four-way connector and the first outlet end of the water tank. The first outlet end of the four-way connector is connected to a second inlet channel. The second outlet end of the four-way connector is connected to the flushing aid valve pipeline. The flushing aid valve pipeline is connected to the flushing aid water path. The third outlet end of the four-way connector is connected to the drain valve. The drain valve is connected to the main flushing water path. The second outlet end of the water tank is connected to the drain valve.

[0017] As can be seen from the above technical solutions,

[0018] 1. This utility model, through the structural design of the flow booster assembly, includes a first water inlet channel and a second water inlet channel. The first water inlet channel and the second water inlet channel are set relatively independently to prevent water from flowing through the water path.

[0019] 2. By setting a gap between the first nozzle and the water inlet end of the booster pipe, and a gap between the second nozzle and the water inlet end of the booster pipe, the flushing capacity of the first and second water inlet channels can be effectively enhanced. Furthermore, the first and second nozzles are arranged in parallel along the radial direction of the booster pipe, thereby achieving a variety of nozzle arrangements.

[0020] 3. The first water inlet channel can be connected to tap water, and the second water inlet channel can be connected to pressurized tap water. This allows the booster pipe assembly to be connected to either tap water directly or pressurized tap water. The valve body controls the opening and closing of the second water inlet channel. When the tap water pressure is insufficient, pressurized tap water flows out through the second water inlet channel and the flushing water path to ensure a flushing effect. When the tap water pressure is sufficient, water with sufficient pressure flows out through the first water inlet channel and the flushing water path. Water from the second water inlet channel can flow out through the flushing water path to enhance the flushing effect. Alternatively, the second water supply channel can be selectively closed to provide water for auxiliary flushing to enhance the main flushing effect. The booster pipe assembly of this invention can have at least two water supply methods. The water flowing out through the flushing water path of this invention can meet the requirements for ensuring a flushing effect and can also improve the main flushing effect.

[0062] 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.

[0063] 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.

[0064] Reference Figures 1-18 As shown, this utility model discloses a water outlet device, including: a flow booster assembly and a flushing water path. The flow booster assembly includes at least one first water inlet channel 11 and at least one second water inlet channel 12. The first water inlet channel 11 and the second water inlet channel 12 are arranged relatively independently. The water flowing out of the first water inlet channel 11 and the water flowing out of the second water inlet channel 12 flows out through the flushing water path, which can prevent water from flowing through the water path. The first water inlet channel 11 can be connected to tap water, such as a water inlet valve or solenoid valve connected to the municipal water supply end. The second water inlet channel 12 can be connected to pressurized tap water, such as a pump.

[0065] Therefore, this utility model, through the structural design of the flow booster assembly, includes a first water inlet channel 11 and a second water inlet channel 12. The first water inlet channel 11 and the second water inlet channel 12 are arranged relatively independently. The first water inlet channel 11 can be connected to tap water, and the second water inlet channel 12 can be connected to pressurized tap water. Thus, the flow booster assembly can be directly connected to tap water or to pressurized tap water. The valve body controls the opening and closing of the second water inlet channel 12. When the tap water pressure is insufficient, the pressurized tap water flows out through the second water inlet channel 12 and the flushing water path to ensure the flushing effect. When the tap water pressure is sufficient, the tap water with sufficient pressure flows out through the first water inlet channel 11 and the flushing water path. Water from the second water inlet channel 12 can flow out from the flushing water path to enhance the flushing effect, or the second water supply channel 12 can be selectively closed to provide water to the auxiliary flushing to enhance the main flushing effect. The flow booster tube assembly of this utility model can have at least two water supply methods. The water flowing out through the flushing water path of this utility model can meet the requirements of ensuring the flushing effect and can also improve the main flushing effect.

[0066] In some embodiments, the booster tube assembly is a Venturi effect booster tube assembly 1, which includes a booster tube 13. The outlet end of the first water inlet channel 11 is provided with a first nozzle 111, and the outlet end of the second water inlet channel 12 is provided with a second nozzle 121. There is a gap between the first nozzle 111 and the water inlet end of the booster tube 13, and a gap between the second nozzle 121 and the water inlet end of the booster tube 13. The outlet end of the booster tube 13 is connected to a flushing water path. Thus, this invention achieves the Venturi effect through this structure, but it is not limited to this; other structures can also be used to achieve the Venturi effect. Here, the "gap" can be the axial gap or radial gap between the first nozzle 111 and the booster tube 13, i.e., ... Figure 2 As shown, the first nozzle 111 does not extend into the flow booster pipe 13 and there is an axial gap along the water flow direction. Alternatively, the first nozzle 111 may extend into the flow booster pipe 13 (not shown) and there may be a radial gap between it and the flow booster pipe 13.

[0067] Preferably, the first nozzle 111 and the second nozzle 121 are arranged radially side by side along the booster pipe 13, the diameter of the first nozzle 111 is smaller than the diameter of the first water inlet channel 11, and the diameter of the second nozzle 121 is smaller than the diameter of the second water inlet channel 12.

[0068] Please see Figures 1 to 2 The first embodiment of the Venturi effect booster tube assembly of this utility model is shown below. Figures 3 to 6 The second embodiment of the Venturi effect flow booster assembly of this utility model is shown below. Figures 7 to 11 The present invention relates to a third embodiment of the Venturi effect booster tube assembly. Figures 12 to 13 The following is an embodiment of the Venturi effect booster tube assembly of the present invention: The main difference between the Venturi effect booster tube assembly embodiments one and two of the present invention and embodiments three and four of the present invention is that: in embodiments one and two of the Venturi effect booster tube assembly of the present invention, the first water inlet channel 11 and the second water inlet channel 12 are two completely independent water inlet channels; in embodiments three and four of the Venturi effect booster tube assembly of the present invention, the first water inlet channel 11 and the second water inlet channel 121 are separated by the valve body 3 described below.

[0069] The main differences between Embodiment 1 and Embodiment 2 of the Venturi effect booster tube assembly of this utility model, and between Embodiment 3 and Embodiment 4 of the Venturi effect booster tube assembly of this utility model, are that the first nozzle 111 and the second nozzle 121 are arranged in different directions relative to the booster tube 13.

[0070] In Embodiments 3 and 4 of the Venturi effect flow booster assembly of this utility model, the water outlet device of this utility model may further include a valve body 3, which is installed between the first water inlet channel 11 and the second water inlet channel 12, and the valve body 3 controls the opening and closing of the second water inlet channel 12.

[0071] In some embodiments, the second water inlet channel 12 is provided with a valve port 122, and the valve body 3 is also provided with a movable cavity 31 and a movable component 32. The movable component 32 can move within the movable cavity 31 to cooperate with the valve port 122 in opening and closing. When water enters the first water inlet channel 11, part of the water flows to the movable cavity 31 to drive the movable component 32 to close the valve port 122, thereby closing the second water inlet channel 12. When water enters the second water inlet channel 12, the movable component 32 opens the valve port 122, thereby opening the second water inlet channel 12. Thus, the opening and closing of the second water inlet channel 12 can be controlled by the difference between the water pressure of the first water inlet channel 11 and the water pressure of the second water inlet channel 12.

[0072] In some embodiments, when the first water inlet channel 11 and the second water inlet channel 12 are filled with water at the same time, and the water pressure of the second water inlet channel 12 is greater than the water pressure of the first water inlet channel 11, the movable part 32 opens the valve port 122.

[0073] In some embodiments, the movable member 32 includes a diaphragm 321, a pressure difference is formed on both sides of the diaphragm 321, and the diaphragm 321 moves under the action of the pressure difference.

[0074] The first water inlet channel 11 is formed in the first pipe, the second water inlet channel 12 is formed in the second pipe, the first pipe and the second pipe are arranged in parallel and connected, and the part where the first pipe and the second pipe are connected forms the movable cavity 31. The valve body 3 is also provided with a water passage hole 331, which connects the movable cavity 31 and the first water inlet channel 11.

[0075] The surface of the diaphragm 321 facing the second water inlet channel 12 is the stop-flow end face, and the surface of the diaphragm 321 facing the first water inlet channel 11 is the back pressure surface; when the first water inlet channel 11 is used alone, such as Figure 8 The water pressure acts on the back pressure surface of the switching diaphragm 321, causing the diaphragm 321 to close the second water inlet channel; when the second water inlet channel 12 is used alone, such as Figure 9 The water pressure acts on the water-stopping end face of the diaphragm 321, opening the second water inlet channel; when both the first water inlet channel 11 and the second water inlet channel 12 are in use: if the water pressure F1 of the first water inlet channel 11 on the diaphragm 321 is greater than the water pressure F2 of the second water inlet channel 12 on the diaphragm 321, then the second water inlet channel 12 is closed, such as... Figure 8The water passage; if the water pressure F1 of the first inlet channel 11 on the diaphragm 321 is less than the water pressure F2 of the second inlet channel 12 on the diaphragm 321, then the second inlet channel 12 is opened. Figure 10 Waterways.

[0076] Combination Figure 10 , Figure 16 and Figure 19 As shown, in this embodiment, the first water inlet channel 11 is connected to a solenoid valve that can be connected to the municipal water supply, and the second water inlet channel 12 is connected to a pump. Further details are as follows:

[0077] When water enters the first inlet channel 11, the water pressure on the diaphragm 321 is P1, corresponding to the cross-sectional area S1 of the back pressure surface. The water pressure provided by the second inlet channel 12 is P2, corresponding to the cross-sectional area S2 of the water-stopping end face. When the second inlet channel 12 opens, water flows out from the second nozzle 121. At this time, the dynamic pressure inside the channel is P3, corresponding to the cross-sectional area S3 of the diaphragm. P2 > P3, S3 > S2. If S1*P1 > S2*P2, the water-stopping end face is closed; if S1*P1 < S2*P2, the water-stopping end face is opened; if S1*P1 > S3*P3, the water-stopping end face is closed. If S1*P1 < S3*P3, the water-stopping end face is opened. When both the first water inlet channel 11 and the second water inlet channel 12 are in the operating state, if S1*P1 < S2*P2, the water-stopping end face is opened. At the moment the water-stopping end face opens, P2 will instantly release pressure to P4 (when the water has not yet filled the entire second water inlet channel 12). If S1*P1 > S2*P4 at this time, the water-stopping end face will be closed again. After closing, the water pressure returns to P2, and the water-stopping end face opens again. This cycle repeats, resulting in the diaphragm 321 opening and closing repeatedly, causing abnormal vibration.

[0078] To address the abnormal vibration, a flushing logic was introduced, such as... Figure 19 As shown:

[0079] 1. During operation, the solenoid valve of the first water inlet channel 11 pauses for T2, preferably T2 ≥ 1s;

[0080] 2. The preferred activation time for the second water inlet channel 12 is T5 ≥ 0.5s, and T5 - T2 ≤ 1s. T5 is to ensure that after the second water inlet channel 12 is activated, P1 = 0 when the first water inlet channel 11 is closed for T2. At this time, S2*P4 > S1*P1, which allows the water-stopping end face to open in time. After the second water inlet channel 12 is filled with water, the water pressure of the first water inlet channel 11 is maintained at P3. After the first water inlet channel 11 resumes water supply for T3, S1*P1 < S3*P3, and the water-stopping end face remains open, preventing reciprocating vibration.

[0081] In some embodiments, the movable member 32 further includes a diaphragm holder 322, the diaphragm 321 is mounted on the diaphragm holder 322, a support 14 is formed in the second water inlet channel 12, the diaphragm holder 322 is mounted on the support 14, and the movable cavity 31 can drive the diaphragm 321 to close the valve port 122.

[0082] Furthermore, the water passage 331 can be provided on the limiting member 33, which is installed on the pipe wall shared by the first water inlet channel 11 and the second water inlet channel 12.

[0083] In some embodiments, a water outlet device further includes a second water inlet connector 4, which is installed at the water inlet end of the second water inlet channel 12, and the diaphragm 321 is disposed between the second water inlet connector 4 and the movable cavity 31.

[0084] This utility model also discloses a flushing system, including the above-mentioned water outlet device, water inlet valve 5, first control valve, second control valve, water tank 6 and pump 7. The first control valve controls the water flowing out of the water inlet valve 5 to enter the first water inlet channel 11, and the second control valve controls the water flowing out of the water inlet valve 5 to enter the water tank 6. The pump 7 is connected to the water tank 6 and the second water inlet channel 12 respectively.

[0085] Preferably, the flushing system of this utility model further includes a four-way connector 8, a flushing auxiliary valve pipeline 91, a drain valve 92, a flushing auxiliary water passage 93, and a main flushing water passage 94. The pump 7 is connected between the water inlet end of the four-way connector 8 and the first water outlet end of the water tank 6. The first water outlet end of the four-way connector 8 is connected to the second water inlet channel 12. The second water outlet end of the four-way connector 8 is connected to the flushing auxiliary valve pipeline 91. The flushing auxiliary valve pipeline 91 is connected to the flushing auxiliary water passage 93. The third water outlet end of the four-way connector 8 is connected to the drain valve 92. The drain valve 92 is connected to the main flushing water passage 94 via a sealed pipeline. The second water outlet end of the water tank 6 is connected to the drain valve 92.

[0086] In this utility model, all water circuit connections can be achieved by using pipes and a sealing method. The above-mentioned flushing water circuit can be the brush ring water circuit 2.

[0087] This utility model also discloses a toilet structure, including a water supply pipe 01, a steel wire rope 02, an integrated valve to a flow booster pipe assembly 03, a brush ring rubber ring 04, ceramic 05, a flushing and venting structure 06, a pump to a flushing booster pipe 07, a pump to an integrated valve pipe 08, a pump to a flow booster pipe assembly 09, and the flushing system of this utility model. The inlet valve 5 and the drain valve 92 can be integrated into a single valve 010. Figure 18As shown, the ceramic 05 has a ceramic brush ring pot surface 051 and a ceramic main flush 052. The ceramic main flush 052 is connected to the main flush water passage 94. The brush ring water passage 2 is located at the brush ring position of the ceramic 05. The water supply pipe 01 is connected to an integrated valve 010. The integrated valve 010 is connected to the flow booster pipe assembly 03 via the integrated valve. The flow booster pipe assembly is connected to the brush ring water passage 2 via the brush ring rubber tube 04. A filter screen 71 is provided at the front end of the pump 7. 7 is connected to the integrated valve 010 via the pump-to-integrated valve pipeline 08. The pump 7 is connected to the booster pipe assembly via the pump-to-boost pipe group pipeline 09. The pump 7 is connected to the booster water circuit 93 via the pump-to-boost pipeline 07. The steel wire rope 02 can act on the drain valve 92 to control the opening and closing of the drain valve 92. The booster water circuit 93 is equipped with a booster exhaust structure 06. The booster exhaust structure 06 can reduce the impact of excessive gas in the water on the main flushing effect during booster flushing and can also prevent blind pipe siphoning.

[0088] The working principle of the toilet structure of this utility model is as follows:

[0089] 1. One of the inlet valves 5 in the integrated valve 010 is equipped with a pre-wetting solenoid valve to achieve pre-brushing of the ring.

[0090] 2. Pump 7 is installed in water tank 6. It draws water from water tank 6 and divides the water into three channels using four-way connector 8. It starts the drain valve 92 of hydraulic cylinder to open, so that water can be discharged from the main flushing water channel 94, brush ring water channel 2 and auxiliary flushing water channel 93.

[0091] 3. The water drawn by pump 7 flows into the brush ring water passage 2, and the water introduced by inlet valve 5 flows into the brush ring water passage 2. After merging at the flow booster pipe assembly, the flow booster flows into the brush ring.

[0092] 4. The water is drained through the drain valve 92 to the main flushing water channel 94, and the water pressurized by the pump 7 flows to the auxiliary flushing water channel 93, thus realizing the main flushing and auxiliary flushing.

[0093] 5. Among them, the other inlet valve 5 of the integrated valve 010 can store water into the water tank 6.

[0094] 6. When the toilet structure of this utility model is without power (pump 7 cannot work), the drain valve 92 can be activated using the steel wire rope 02 to ensure the main flushing function.

[0095] 7. When the toilet structure of this utility model has no water pressure (the inlet valve 5 cannot work), the pump 7 can be used to supply water to the second inlet channel to achieve the brush ring.
