Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and more specifically, to a toilet with a foam shield and toilet cleaner dispensing function. Background Technology

[0002] To reduce splashing and block odors, most existing smart toilets are equipped with a foam shield device, such as the one disclosed in Chinese patent CN215483362U. This foam shield device combines the brush ring water path and the main flushing channel to achieve its function. However, the foam shield primarily relies on physical barriers to prevent splashing, odor control, and antibacterial properties, lacking chemical cleaning capabilities. To address this, some smart toilets also include a toilet cleaner dispensing function for cleaning and sterilization. For example, Chinese patent CN116446501A discloses a toilet with a toilet cleaner dispensing function. By incorporating a flush trigger device and a dispensing device on the toilet seat, it achieves real-time replenishment of toilet cleaner, solving the problem of frequent liquid toilet cleaner additions. However, few existing toilets integrate both cleaning functions into a single unit. This is because they are structurally complex, take up a lot of space, are difficult to universally adopt, have high costs, and lack market competitiveness. Summary of the Invention

[0003] This invention discloses a toilet with a foam shield and toilet cleaner dispensing functions, aiming to improve the problem that existing toilets are difficult to integrate two cleaning functions.

[0004] The present invention adopts the following solution: A toilet with a foam shield and toilet cleaner dispensing functions includes a toilet body and a liquid outlet box disposed within the toilet body. The toilet body has a flushing water path and a brush ring water path communicating with a water tank. The liquid outlet box includes a first liquid storage chamber, a second liquid storage chamber, a mixing chamber, and a liquid suction structure. The first liquid storage chamber is used to hold foaming concentrate, and the second liquid storage chamber is used to hold toilet cleaner. The outlet end of the mixing chamber is equipped with a foaming head, and the foaming end of the foaming head is connected to the brush ring water path. The liquid suction structure includes a movable pushing member, which, by driving the pushing member to move, delivers the foaming concentrate into the mixing chamber and the toilet cleaner into the water tank.

[0005] As a further improvement, the toilet body is equipped with a water pump, the water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the flushing water path and the brush ring water path.

[0006] As a further improvement, the pusher is disposed in the seat, which has a water inlet channel communicating with the mixing chamber, a lower pressure chamber communicating with the first liquid storage chamber, and an upper pressure chamber communicating with the second liquid storage chamber; wherein, the liquid outlet of the lower pressure chamber is communicating with the mixing chamber, and the pusher is configured to move under the action of water flow pressure when water enters the water inlet channel, so that the volume of the two pressure chambers changes with the movement of the pusher, so that the two liquids can be drawn into the corresponding pressure chambers and discharged from the corresponding pressure chambers.

[0007] As a further improvement, the water inlet channel is supplied with water via a distribution valve, the inlet end of which is connected to the water tank.

[0008] As a further improvement, the lower pressure chamber is connected to the first liquid inlet channel and the first liquid outlet channel, the upper pressure chamber is connected to the second liquid inlet channel and the second liquid outlet channel, the first liquid inlet channel is used to connect to the first liquid storage chamber, the first liquid outlet channel is connected to the liquid inlet of the mixing chamber, the second liquid inlet channel is connected to the second liquid storage chamber, and the second liquid outlet channel is connected to the liquid inlet of the water tank.

[0009] As a further improvement, one-way valves are provided in the first liquid inlet channel, the first liquid outlet channel, the second liquid inlet channel, and the second liquid outlet channel.

[0010] As a further improvement, when the pusher moves, the volume change of the upper pressure chamber is opposite to the volume change of the lower pressure chamber, so that the order in which the second liquid outlet channel and the first liquid outlet channel output liquid are different.

[0011] As a further improvement, the end of the pusher away from the water inlet channel is abutted against an elastic element. When water is introduced, the pusher compresses the elastic element under the action of fluid pressure, thereby reducing the volume of the lower pressure chamber and increasing the volume of the upper pressure chamber. When water is stopped, the pusher resets under the elastic force of the elastic element, at which time the volume of the lower pressure chamber increases and the volume of the upper pressure chamber decreases.

[0012] As a further improvement, the pushing member includes a driving diaphragm, an upper bracket, a working diaphragm, and a lower bracket arranged sequentially along the axial direction of the seat body. The peripheries of the driving diaphragm and the working diaphragm are fixedly connected to the seat body. The upper bracket and the lower bracket are respectively sleeved on the upper and lower ends of the working diaphragm. The elastic member abuts against the lower bracket. The driving diaphragm and the working diaphragm form the upper pressure cavity, and the working diaphragm and the inner bottom surface of the seat body form the lower pressure cavity.

[0013] As a further improvement, the base includes a main body and a water inlet cover and a bottom cover disposed at both ends of the main body. The main body has a mounting cavity for assembling the pusher. The drive diaphragm is disposed at the top of the main body, and its periphery is clamped to the main body via the water inlet cover. The working diaphragm is disposed at the bottom of the main body, and its periphery is clamped to the bottom cover via the main body.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. This application achieves two functions—foam shield and toilet cleaner dispensing—by incorporating a dispensing box compatible with both foaming agent and toilet cleaner liquid on the toilet body, and by adding a liquid-absorbing structure to the dispensing box. Furthermore, integrating the liquid storage and absorption structures into the dispensing box results in a more compact structure, reducing its volume and improving its compatibility, thereby lowering the cost of the dispensing box.

[0015] 2. The water pressure drives the actuating component to move, changing the volume of the two pressure chambers, thereby achieving the intake and discharge of two liquids. The liquid transport and mixing require no electronic components, resulting in a simple structure and reduced costs. Furthermore, the lifespan of the dispensing box is not affected by electronic components, extending its service life and facilitating its application in toilet bodies, thus enhancing the toilet's market competitiveness. In addition, the water flow in the inlet channel can be used to drive the actuating component and also enter the mixing chamber to mix with the foaming agent, allowing for multiple uses of water and simplifying the water system structure.

[0016] 3. The reciprocating movement of the pusher can realize the sequential output of two liquids without the need for solenoid valves or other controls to control the output interval of the two liquids, resulting in a simple structure.

[0017] 4. One-way valves are installed in the first liquid inlet channel, the first liquid outlet channel, the second liquid inlet channel, and the second liquid outlet channel to ensure one-way flow of liquid and prevent liquid backflow, which could cause contamination.

[0018] 5. The actuator includes a drive diaphragm and a working diaphragm. The arrangement of the two diaphragms can both seal with the seat and provide elastic movement, thereby simplifying the structure and reducing the resistance of the actuator during movement, so as to ensure that the water flow pressure can drive the actuator to move.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The terms “top,” “bottom,” “upper,” “lower,” “left,” “right,” “front,” “back,” and similar expressions used in this document are for illustrative purposes only. The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0024] Combination Figures 1 to 15 This embodiment provides a toilet with foam shield and toilet cleaner dispensing functions, including a toilet body 3 and a liquid outlet box 1 disposed in the toilet body 3. The toilet body 3 has a flushing water passage 32 and a brush ring water passage 33 connected to the water tank 31. The liquid outlet box 1 includes a first liquid storage chamber 11, a second liquid storage chamber 12, a mixing chamber 13, and a liquid suction structure 2. The first liquid storage chamber 11 is used to hold foaming concentrate, the second liquid storage chamber 12 is used to hold toilet cleaner, and the liquid outlet end of the mixing chamber 13 is equipped with a foaming head 15, the foaming end of which is connected to the brush ring water passage 33. The liquid suction structure 2 includes a movable pusher 23, which is driven to move so that the foaming concentrate is delivered to the mixing chamber 13 and the toilet cleaner is delivered to the water tank 31.

[0025] For example, the foaming agent is a toilet foaming agent. It enters the mixing chamber 13 and mixes with the water to form a foaming liquid. The foaming liquid flows out of the mixing chamber 13 and passes through the foaming head 15 to achieve foaming. The foaming head can be a Venturi foaming head. The structure and working principle of the Venturi foaming head are existing technologies and will not be described in detail here. The foaming liquid discharged from the foaming head 15 enters the brush ring water passage 33 and enters the toilet bowl along the brush ring water passage 33, thereby forming a foam shield on the toilet bowl surface to prevent water splashing and remove odors. When the user needs to flush, the toilet cleaner is delivered to the water tank 31 to mix with the water in the water tank 31. This causes the brush ring water passage 33 and the flushing water passage 32 to simultaneously flow out water containing toilet cleaner, cleaning and sterilizing the entire toilet bowl surface and ensuring the hygiene of the toilet.

[0026] It should be noted that in this embodiment, by setting a liquid dispensing box 1 compatible with both foaming agent and toilet cleaner on the toilet body 3, and by setting a liquid absorption structure 2 on the liquid dispensing box 1, the two functions of foam shield and toilet cleaner dispensing are realized. At the same time, integrating the liquid storage and liquid absorption structure into the liquid dispensing box 1 results in a more compact structure, reduces the structural volume, improves the compatibility of the liquid dispensing box 1, and thus reduces the cost of the liquid dispensing box 1.

[0027] For example, the toilet body 3 is equipped with a water pump 34. The inlet of the water pump 34 is connected to the water tank 31, and the outlet of the water pump 34 is connected to the flushing water path 32 and the brush ring water path 33. The water supply to the flushing water path 32 and the brush ring water path 33 is achieved by controlling the opening and closing of the water pump 34. This ensures the pressure of the water jet and the cleaning effect of the water flow. Both the brush ring water path 33 and the flushing water path 32 are pipes to simplify the water system and facilitate installation.

[0028] In a preferred embodiment, the pusher 23 is disposed within the base 27, which has a water inlet channel 21 communicating with the mixing chamber 13, a lower pressure chamber 22 communicating with the first liquid storage chamber 11, and an upper pressure chamber 24 communicating with the second liquid storage chamber 12. The outlet end of the lower pressure chamber 22 is connected to the mixing chamber 13. The pusher 23 is configured to move under water pressure when water enters the water inlet channel 21, so that the volumes of the two pressure chambers change with the movement of the pusher 23, allowing the two liquids to be drawn into and discharged from their respective pressure chambers. For example, the water inlet channel 21 is supplied with water via a distribution valve 29, the inlet end of which is connected to the water tank 31. The distribution valve 29 is operablely controlled to open and close, thereby controlling the water intake of the water inlet channel 21. When water enters the inlet channel 21, it drives the pusher 23 to move, causing the volumes of the two pressure chambers to change accordingly. When the volume of the lower pressure chamber 22 increases, a negative pressure is generated within it, drawing the foaming liquid into the lower pressure chamber 22. When the volume of the lower pressure chamber 22 decreases, the foaming liquid in the lower pressure chamber 22 is transported to the mixing chamber 13 to mix with the water flow in the mixing chamber 13 to form a foaming liquid. Similarly, when the volume of the upper pressure chamber 24 increases, a negative pressure is generated within it, drawing the toilet cleaner into the upper pressure chamber 24. When the volume of the upper pressure chamber 24 decreases, the toilet cleaner is discharged from the upper pressure chamber 24. This is not a limitation and is not specifically specified. The liquid transport and mixing do not require electronic components, resulting in a simple structure that reduces the cost of the liquid outlet box 1. Furthermore, the lifespan of the liquid outlet box 1 is not affected by electronic components, thus extending its service life. This facilitates the application of the liquid outlet box 1 in products and enhances the toilet's market competitiveness. In addition, the water flow in the water inlet channel 21 can be used to drive the pusher 23, and can also enter the mixing chamber 13 to mix with the foaming liquid. This multi-purpose water flow simplifies the water circuit structure of the device.

[0029] As a further improvement, the lower pressure chamber 22 is connected to the first inlet channel 221 and the first outlet channel 222, and the upper pressure chamber 24 is connected to the second inlet channel 241 and the second outlet channel 242. The first inlet channel 221 is used to connect to the first storage chamber 11, the first outlet channel 222 is connected to the inlet 131 of the mixing chamber 13, the second inlet channel 241 is connected to the second storage chamber 12, and the second outlet channel 242 is connected to the liquid inlet of the water tank 31. When the lower pressure chamber 22 draws in liquid, the foaming agent enters the lower pressure chamber 22 along the first inlet channel 221. When the lower pressure chamber 22 discharges liquid, the foaming agent flows to the mixing chamber 13 along the first outlet channel 222. When the upper pressure chamber 24 draws in liquid, the toilet cleaner enters the upper pressure chamber 24 along the second inlet channel 241. When the upper pressure chamber 24 discharges liquid, the toilet cleaner flows to the outlet 144 along the second outlet channel 242. Preferably, a one-way valve 26 is provided in each of the first liquid inlet channel 221, the first liquid outlet channel 222, the second liquid inlet channel 241, and the second liquid outlet channel 242 to ensure unidirectional flow of the liquid and prevent liquid backflow and contamination.

[0030] Based on the above embodiments, in an optional embodiment of the present invention, when the pusher 23 moves, the volume change of the upper pressure chamber 24 is opposite to the volume change of the lower pressure chamber 22, so that the order in which the second liquid outlet channel 242 and the first liquid outlet channel 222 output liquid is different. For example, the end of the pusher 23 away from the water inlet channel 21 is provided with an elastic member 25. When water enters, the pusher 23 compresses the elastic member 25 under the action of water flow pressure, so that the volume of the lower pressure chamber 22 decreases and the volume of the upper pressure chamber 24 increases; when water enters, the pusher 23 returns to its original position under the elastic force of the elastic member 25, at which time the volume of the lower pressure chamber 22 increases and the volume of the upper pressure chamber 24 decreases. The elastic member 25 can be a spring, see reference. Figure 7 and Figure 8 When the pusher 23 moves downward under the pressure of the water flow, the volume of the lower pressure chamber 22 decreases, and the foaming liquid in the lower pressure chamber 22 is forced into the first liquid outlet channel 222 to enter the mixing chamber 13 and mix with the water flow. At this time, the volume of the upper pressure chamber 24 increases, and a negative pressure is generated in the upper pressure chamber 24, which draws the toilet cleaner into the upper pressure chamber 24 along the second liquid inlet channel 241. When the water flow stops, the pusher 23 moves upward and resets under the action of the elastic member 25. The volume of the lower pressure chamber 22 increases, and a negative pressure is generated in the lower pressure chamber 22, which draws the foaming liquid into the lower pressure chamber 22 along the first liquid inlet channel 221. At this time, the volume of the upper pressure chamber 24 decreases, and the toilet cleaner in the upper pressure chamber 24 is forced into the second liquid outlet channel 242 to enter the water tank 31, and so on.

[0031] It is easy to understand that in this embodiment, a single reciprocating movement of the pusher 23 enables the sequential output of the two liquids, eliminating the need for solenoid valves or other mechanisms to control the output interval, resulting in a simple structure. Outputting the two liquids at different times allows for two cleaning modes: first outputting foaming liquid, then toilet cleaning liquid, providing convenience for the user. Compared to the liquid control structure of existing smart toilets, the advantages of this embodiment are obvious.

[0032] In another embodiment, the pushing member 23 includes a driving diaphragm 231, an upper support 232, a working diaphragm 233, and a lower support 234 arranged sequentially along the axial direction of the base 27. The peripheries of the driving diaphragm 231 and the working diaphragm 233 are fixedly connected to the base 27. The upper support 232 and the lower support 234 are respectively sleeved on the upper and lower ends of the working diaphragm 233. The elastic member 25 abuts against the lower support 234. An upper pressure chamber 24 is formed between the driving diaphragm 231 and the working diaphragm 233, and a lower pressure chamber 22 is formed between the working diaphragm 233 and the inner bottom surface of the base 27. When water enters, the driving diaphragm 231 presses against the upper support 232 under the action of water flow pressure, so as to drive the working diaphragm 233 and the lower support 234 to move downward synchronously. When the water flow stops, the elastic member 25 abuts against the lower support 234 and moves upward, so as to drive the working diaphragm 233 and the upper support 232 to move and reset synchronously. Both the driving diaphragm 231 and the working diaphragm 233 are made of soft rubber or silicone. The two diaphragms not only seal against the base 27 but also provide elastic movement, thus simplifying the structure and reducing the resistance of the actuator 23 during movement, ensuring that the water pressure can drive the actuator 23. The upper support 232 and the lower support 234 ensure balanced force on the working diaphragm 233 and maintain the correct direction of movement, thus ensuring the volume changes of the upper pressure chamber 24 and the lower pressure chamber 22.

[0033] Furthermore, the main body 273 has a mounting cavity for assembling the pusher 23. The drive diaphragm 231 is disposed on the top of the main body 273, and its periphery is clamped to the main body 273 via the water inlet cover 274. The working diaphragm 233 is disposed on the bottom of the main body 273, and its periphery is clamped to the bottom cover 275 via the main body 273. During installation, the drive diaphragm 231 is placed on the top of the main body 273, and then the water inlet cover 274 is locked to the main body 273. Then, the working diaphragm 233, which is fitted with the upper bracket 232 and the lower bracket 234, is placed on the bottom of the main body 273, and then the elastic member 25 is inserted. Finally, the bottom cover 275 is locked to the main body 273. The structure is simple and the installation is convenient. The water inlet cover 274 and the main body 273, as well as the bottom cover 275 and the main body 273, can be locked with screws. Furthermore, a three-way connector is formed on the water inlet cover 274, the water inlet channel 21 is the water inlet end of the three-way connector, one of the water outlet ends of the three-way connector is formed with a water inlet 211, and the other water outlet end is used to connect to the mixing chamber 13. The water inlet cover 274 enables the drive water to flow back into the mixing chamber 13. The water inlet 211 is arranged to extend axially to avoid energy loss and ensure that the water pressure on the drive diaphragm 231 can drive the working diaphragm 233 to move.

[0034] In other embodiments, the top of the seat 27 is provided with a water inlet 211 communicating with the water inlet channel 21, and the pusher 23 is positioned directly opposite the water inlet 211. The bottom of the seat 27 is provided with a first liquid inlet 271 and a first liquid outlet 272 communicating with the lower pressure chamber 22. The side of the seat 27 is provided with a liquid passage pipe 28 communicating with the upper pressure chamber 24. The liquid passage pipe 28 is provided with a second liquid inlet 281 and a second liquid outlet 282. The first liquid inlet channel 221 and the first liquid outlet channel 222 are respectively connected to the first liquid inlet 271 and the first liquid outlet 272. The second liquid inlet channel 241 and the second liquid outlet channel 242 are respectively connected to the second liquid inlet 281 and the second liquid outlet 282. Liquid inlet and outlet structures are provided on the top, bottom, and side of the seat 27 to make the structure of the seat 27 more compact, reduce the structural space, and ensure the volume of the liquid outlet box 1.

[0035] Based on the above embodiments, in an optional embodiment of the present invention, the first liquid storage chamber 11 and the second liquid storage chamber 12 are integrally formed with the liquid outlet box 1, and the mixing chamber 13 is a cylindrical component disposed within the first liquid storage chamber 11 to facilitate the assembly and disassembly of the mixing chamber 13. Further, the liquid outlet box 1 includes a top cover 14, which has mounting holes 141 for assembling each one-way valve 26, a water inlet 142 communicating with the mixing chamber 13, a mixed liquid outlet 143, a second liquid filling port 121 communicating with the second liquid storage chamber 12, and an outlet 144 communicating with the second liquid outlet channel 242. The bottom of the liquid outlet box 1 is provided with a first liquid filling port 111 communicating with the first liquid storage chamber 11. The provision of the first liquid filling port 111 and the second liquid filling port 121 facilitates the replenishment of foaming concentrate and toilet cleaner. The top cover 14 has multiple liquid outlets formed on it. The seat 27 is fixed to the top cover 14 with screws. The structure is compact and easy to install onto the toilet body 3. It also facilitates replacement and maintenance, and simplifies the connection pipeline between the liquid outlet box 1 and the toilet body 3. Preferably, the liquid outlets can be connected by flexible hoses to facilitate pipeline layout and reduce mold costs.
