Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, specifically a hybrid flushing device and a toilet. Background Technology

[0002] As people's living standards improve, smart toilets have become a popular choice among consumers. Most smart toilets on the market use a direct connection to the municipal water supply, relying on the pressure of the water pipes for flushing. This design is highly dependent on the water pressure of the municipal water supply for effective flushing and waste removal. When the water supply network pressure fluctuates (such as during peak water usage, insufficient water pressure in high-rise buildings, or reduced water pressure due to pipeline maintenance), the flushing power is significantly weakened, directly resulting in poor waste removal performance and seriously affecting user experience and hygiene.

[0003] Patent ZL202510123725.8 discloses a flushing system and toilet. The flushing system includes a water tank and a booster pump. The working principle is that water is pre-stored in the tank, and during flushing, the booster pump pressurizes the water, forcefully expelling it to complete the flushing process. This design effectively overcomes the dependence on unstable tap water pressure, providing a stable and powerful flushing effect even in low water pressure environments, significantly improving flushing reliability. However, this pump-driven solution has the following drawbacks: it typically relies on household electricity; if the mains power is interrupted, even if there is stored water in the tank, it cannot be effectively flushed. While using a battery power source is feasible to avoid this, it significantly increases costs, reducing the practicality and economic efficiency of the solution. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a hybrid flushing device and toilet, which has the advantage of maintaining flushing function even during power outages.

[0005] The first aspect of this utility model is to provide a hybrid power flushing device, including a water tank, a flushing assembly disposed inside the water tank, and an external water supply assembly disposed outside the water tank, wherein:

[0006] The flushing assembly includes a water outlet pipe, a first nozzle and a second nozzle. Both the first nozzle and the second nozzle are connected to the water inlet of the water outlet pipe. The first nozzle is connected to a water pump located in the water tank, and the second nozzle is connected to an external water supply assembly.

[0007] A water inlet gap is formed between the water inlet of the outlet pipe and the first and second nozzles;

[0008] The water pump starts to allow water from the tank to enter the first nozzle, or the external water supply assembly starts to allow external water to enter the second nozzle.

[0009] Furthermore, the first nozzle and the second nozzle are arranged side by side below the inlet of the water outlet pipe, and the first spray nozzle of the first nozzle and the second spray nozzle of the second nozzle are both located below the inlet of the water outlet pipe.

[0010] Furthermore, the cross-sectional areas of both the first and second water nozzles are smaller than the cross-sectional area of ​​the water inlet of the outlet pipe.

[0011] Furthermore, the first and second nozzles are integrally formed, and a horizontal connection is formed at the end opposite to the water inlet of the water outlet pipe. The horizontal connection is connected to the water outlet pipe through a plurality of circumferentially spaced connectors, and a water inlet gap is formed between adjacent connectors.

[0012] Furthermore, the external water supply assembly includes a water supply connection pipe connected to the second nozzle, a tap water pipe connected to the water supply connection pipe, and a control switch for controlling the tap water to enter the second nozzle.

[0013] Furthermore, the external water supply component also includes a three-way manifold, which has a first connection port, a second connection port and a third connection port. The first connection port is connected to the water supply connection pipe, the second connection port is connected to the tap water pipe, and the third connection port is connected to the inlet valve.

[0014] Furthermore, the control switch is located at the first connection port of the three-way manifold.

[0015] Furthermore, the water pump is fixed inside the water tank by a mounting bracket.

[0016] The second aspect of this utility model is to provide a toilet that includes a hybrid flushing device according to any one of the above.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The hybrid flushing device of this application includes a water outlet pipe, a first nozzle, and a second nozzle. Both the first nozzle and the second nozzle are connected to the inlet of the water outlet pipe. The first nozzle is connected to a water pump located in the water tank, and the second nozzle is connected to an external water supply assembly. A water inlet gap is formed between the inlet of the water outlet pipe and the first and second nozzles. When there is no power outage, the toilet flushing is powered by the water pump. The water pump draws water from the water tank into the first nozzle, and the water from the water tank and the water sprayed from the first nozzle are flushed into the toilet bowl through the cooperation of the first nozzle and the water outlet pipe to complete the sewage discharge. When there is a power outage, the toilet flushing is powered by the pressure provided by the external water supply assembly. When the user flushes, the external water supply assembly is activated, allowing external tap water to enter the second nozzle. The water is then discharged into the toilet bowl through the cooperation of the second nozzle and the water outlet pipe to complete the toilet cleaning. The two flushing systems operate independently, ensuring that the toilet flushing is not absolutely dependent on the power supply.

[0019] (2) The hybrid flushing device of this application designs the cross-sectional area of ​​the first spray nozzle and the cross-sectional area of ​​the second spray nozzle to be smaller than the cross-sectional area of ​​the inlet of the outlet pipe, so that the water flow velocity increases when passing through the first spray nozzle or the second spray nozzle, forming a high-speed jet. The high-speed jet works in conjunction with the inlet gap to generate the Venturi effect, thereby driving the water in the tank into the outlet pipe, increasing the flushing water volume of the toilet, and at the same time reducing the noise generated during flushing.

Detailed Implementation

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is in conjunction with the appendix Figure 1To be continued Figure 4 The present invention will be described in detail with specific embodiments.

[0028] See Figures 1 to 4 This utility model provides a hybrid power flushing device, including a water tank 1, a flushing assembly 2 disposed within the water tank 1, and an external water supply assembly 3 disposed outside the water tank 1. The flushing assembly 2 includes a water outlet pipe 23, a first nozzle 21, and a second nozzle 22. Both the first nozzle 21 and the second nozzle 22 are connected to the water inlet 231 of the water outlet pipe 23, and the water outlet of the water outlet pipe 23 is connected to the toilet bowl for flushing. The first nozzle 21 is connected to a water pump 24 located within the water tank 1, and the second nozzle 22 is connected to the external water supply assembly 3. The water inlet 231 of the water outlet pipe 23 is connected to the first nozzle... A water inlet gap 25 is formed between the first nozzle 21 and the second nozzle 22. This gap allows water from the water tank 1 to enter the outlet pipe 23 and mix with the water sprayed from the first nozzle 21 or the second nozzle 22. When the water pump 24 is activated, water from the water tank 1 enters the first nozzle 21 and is sprayed into the outlet pipe 23. Simultaneously, water from the water tank 1 is guided into the outlet pipe 23 through the water inlet gap 25. Alternatively, the external water supply assembly 3 is activated, allowing external water to enter the second nozzle 22 and be sprayed into the outlet pipe 23. Simultaneously, water from the water tank 1 is guided into the outlet pipe 23 through the water inlet gap 25. Optionally, the first nozzle 21 is connected to the water pump 24 via a flexible hose or a rigid pipe, and the second nozzle 22 can be connected to the external water supply assembly 3 using a quick-release coupling or a threaded pipe structure.

[0029] With the above scheme, under uninterrupted power supply conditions, the toilet flushing is powered by the water pump 24. The water pump 24 draws water from the tank 1 and enters the first nozzle 21. The first nozzle 21, in conjunction with the water outlet pipe 23, flushes the water from the tank 1 and the water sprayed from the first nozzle 21 into the toilet bowl to complete the waste disposal. In the event of a power outage, the toilet flushing is powered by the pressure provided by the external water supply component 3. When the user flushes, the external water supply component 3 is activated, allowing external tap water to enter the second nozzle 22. The second nozzle 22, in conjunction with the water outlet pipe 23, then discharges the water into the toilet bowl to complete the cleaning process. These two flushing systems operate independently, ensuring that the toilet flushing process is not entirely dependent on electricity.

[0030] For further details, please refer to [link / reference]. Figures 2 to 4The first nozzle 21 and the second nozzle 22 are arranged side by side below the inlet of the outlet pipe 23, and the first spray nozzle 211 of the first nozzle 21 and the second spray nozzle 221 of the second nozzle 22 are both located below the inlet 231 of the outlet pipe 23. Water in both the first nozzle 21 and the second nozzle 22 can be sprayed upward into the outlet pipe 23. Specifically, when the water pump 24 is started, water in the water tank 1 is sprayed upward through the first nozzle 21 to the inlet 231 of the outlet pipe 23; similarly, when the external water supply component 3 is started, external water is sprayed upward through the second nozzle 22 to the inlet 231 of the outlet pipe 23. The above structure can maintain an effective water flow path through different nozzles when the external water supply pressure is insufficient or the water pump is powered off, ensuring that the flushing action is completed normally.

[0031] Furthermore, the cross-sectional areas of the first spray nozzle 211 and the second spray nozzle 221 are both smaller than the cross-sectional area of ​​the inlet 231 of the outlet pipe 23. When the water pump 23 or the external water supply component 3 is started, water flows into the outlet pipe 23 from the inlet 231. Since the cross-sectional areas of the first spray nozzle 211 and the second spray nozzle 221 are both smaller than the cross-sectional area of ​​the inlet 231, the water flow velocity increases when passing through the first spray nozzle 211 or the second spray nozzle 221, forming a high-speed jet. The high-speed jet works in conjunction with the inlet gap 25 to produce a Venturi effect, which in turn drives the water in the tank 1 into the outlet pipe 23, increasing the flushing water volume of the toilet. At the same time, since the water pump 24 and the inlet gap 25 are both surrounded by water in the tank 1, the noise generated during flushing can be reduced. The ingenious design of the above structure allows the toilet to complete normal flushing even under low water pressure.

[0032] This application establishes a cross-sectional area gradient between the first water inlet 211, the second water inlet 221, and the inlet 231, thereby forcibly increasing the water flow velocity in both water supply modes and eliminating dependence on a single water supply pressure.

[0033] Furthermore, both the first nozzle 211 and the second nozzle 221 are crescent-shaped. A crescent-shaped nozzle refers to a nozzle with a continuously curved arc-shaped edge, its cross-section having a concave center and convex sides. This shape guides the water flow through the arc-shaped edge, creating a diffusion angle and enhancing the water flow coverage. Because the water flow velocity from the first nozzle 211 and the second nozzle 221 is relatively high, low pressure is generated in their vicinity, creating an adsorption effect, which then guides the water in the water tank 1 into the outlet pipe 23 through the inlet gap 25.

[0034] Furthermore, the first nozzle 21 and the second nozzle 22 are integrally formed, and a horizontal connecting portion 26 is formed at the end opposite to the water inlet 231 of the water outlet pipe 23. The horizontal connecting portion 26 is connected to the water outlet pipe 23 through a plurality of circumferentially spaced connectors 27, and a water inlet gap is formed between adjacent connectors 27. Optionally, the connectors 27 are fixed units distributed on the outer edge of the horizontal connecting portion 26, with one end fixedly connected to the water outlet pipe 23 and the other end fixedly connected to the horizontal connecting portion 26; the water inlet gap 25 refers to the open area between adjacent connectors 27, and the size of the water inlet gap 25 can be controlled by adjusting the water flow and spacing of the connectors 27, thereby achieving a uniform distribution of water flow between the horizontal connecting portion 26 and the water outlet pipe 23. The integral forming means that the first nozzle 21 and the second nozzle 22 are formed into an integral structure through mold injection molding or die casting process, thereby reducing the assembly errors and sealing failure risks that may occur with a split structure. When the external water supply component 3 or the water pump 24 is started, the water flows through the second nozzle 22 or the first nozzle 21 into the inlet 231 of the outlet pipe 23, while some water flows directly into the outlet pipe 23 from the inlet gap 25, forming a mixed water flow path to realize the flushing function of the toilet.

[0035] For further details, please refer to [link / reference]. Figure 2 The external water supply component 3 includes a water supply connection pipe 31 connected to the second sprinkler head 22, a tap water pipe 32 connected to the water supply connection pipe 31, and a control switch 33 for controlling the flow of tap water into the second sprinkler head 22. The water supply connection pipe 31 is a hollow pipe structure connecting the second sprinkler head 22 to an external water source, its function being to establish a fluid channel between the second sprinkler head 22 and the external water source. The tap water pipe 32 refers to the water supply pipe of a municipal water supply system. The control switch 33 is an actuator for controlling the flow of water, specifically a manual ball valve or a solenoid valve, its function being to selectively open or close the external water supply path according to operating conditions. Preferably, both the first sprinkler head 21 and the second sprinkler head 22 in this application are L-shaped, and the L-shaped structure facilitates connection to the water pump 24 and the water supply connection pipe 31 within the limited space of the water tank.

[0036] When a power outage prevents the water pump 24 from operating, the control switch 33 can be manually or automatically activated, allowing tap water to flow through the tap water pipe 32 and the water supply connection pipe 31 into the second spray head 22. After passing through the second spray head 22, the water enters the outlet pipe 23, generating flushing power. At this time, the external water supply component 3 acts as a backup flushing power source. Under normal operating conditions, the control switch 33 remains closed to avoid interference with the water pump 24's drive mode.

[0037] For further details, please refer to [link / reference]. Figure 2The external water supply component 3 also includes a three-way water distributor 34, which has a first connection port, a second connection port, and a third connection port. The first connection port is connected to the water supply connection pipe 31, the second connection port is connected to the tap water pipe 32, and the third connection port is connected to an inlet valve 35. Specifically, the three-way water distributor 34 forms a water diversion structure through the three connection ports. When the control switch 33 is turned on, tap water enters the three-way water distributor 34 through the second connection port and flows to the second spray head 22 through the first connection port to form a normal flushing mode. When the water in the tank is insufficient, the inlet valve 35 opens, creating a passage between the third connection port and the tap water pipe 32, and tap water flows into the water tank 1. When the water in the tank 1 is sufficient, the inlet valve 35 closes.

[0038] Furthermore, the control switch 33 is located at the first connection port of the three-way water distributor 34. The first connection port of the three-way water distributor 34 serves as the connection node between the water supply connection pipe 31 and the second sprinkler head 22, and the control switch 33 is integrated at the first connection port. When external water supply is required, the control switch 33 is triggered and opened, allowing water in the tap water pipe 32 to flow through the second connection port of the three-way water distributor 34 into the first connection port, and then be delivered to the second sprinkler head 22 through the water supply connection pipe 31. This arrangement allows the fluid control node to be located directly at the beginning of the water supply path, enabling precise control of the flow of water into the second sprinkler head 22.

[0039] Furthermore, the water pump 24 is fixed inside the water tank 1 by the mounting bracket 4. The mounting bracket 4 is connected to the inner wall of the water tank 1 through preset fixing points to form a stable support frame. The water pump 24 is fixed in the preset mounting groove of the mounting bracket 4 by bolt fastening or embedded snap-fit, and the shape of the mounting groove matches the outline of the water pump 24's outer shell to form a contact fixation. When the water pump 24 is working, the mechanical vibration generated is absorbed by the rigid structure of the mounting bracket 4, and rubber shock-absorbing pads can be set at the bottom of the mounting bracket 4 to further reduce vibration transmission.

[0040] This utility model also provides a toilet, including any of the above-mentioned hybrid flushing devices. The toilet provided in this application adopts all the technical solutions of all embodiments of the above-mentioned hybrid flushing devices, and therefore has at least all the beneficial effects brought about by the technical solutions of the above-mentioned hybrid flushing devices, which will not be described in detail here.
