Technical Field

[0001] This utility model relates to the field of toilets, specifically to a toilet tank lid assembly and a smart toilet. Background Technology

[0002] Smart toilets have gained widespread use due to their significant improvement in toilet comfort, hygiene, and convenience. Currently, most mainstream smart toilet products on the market adopt an integrated design. Their core functional modules, such as the flushing water assembly, instant heating module, and electronic control module, are highly integrated into the ceramic body of the smart toilet and the smart toilet seat located on top of it.

[0003] While this highly integrated, one-piece design offers advantages in terms of product integrity and aesthetics, it presents a significant challenge when repairs are needed. Due to the highly integrated components and compact space, repairs often require disassembling the entire smart toilet seat and even parts of the ceramic structure, making self-repair virtually impossible. Users are forced to rely on professional repair service personnel from the manufacturer or a third party. This not only prolongs the troubleshooting process (waiting for appointments and on-site visits) but also directly leads to higher service costs.

[0004] Therefore, it is urgent to solve the problems of inconvenient and costly after-sales maintenance for mainstream smart toilets. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a toilet tank cover assembly that can be easily replaced as a whole after an abnormality occurs, thus solving the problem of inconvenient after-sales maintenance.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a toilet tank lid assembly, comprising: The main body of the toilet tank lid includes a cover body and a housing, wherein the cover body is fitted onto the upper opening of the housing, and the housing has a downwardly extending isolation chamber for sealing assembly with a mating chamber inside the toilet tank; A hot water generation and supply component is installed inside the housing, with its inlet connected to a cold water inlet pipe and its outlet connected to a hot water outlet pipe. An electrical control component is connected to the hot water generation and supply component and is also connected to a communication line; wherein, The cold water inlet pipe, the hot water outlet pipe, and the communication line extend downwards from the housing along the isolation chamber and are used to connect with corresponding pipelines from the mating chamber.

[0007] Further, a specific structure for a hot water generation and supply component is provided, comprising an inlet solenoid valve, an isolation water tank, a water pump, and an instant heating unit, all installed within the housing and connected in sequence; wherein, The cold water inlet pipe is connected to the inlet solenoid valve, and the hot water outlet pipe is connected to the instant heating unit.

[0008] Furthermore, the toilet tank lid assembly also includes an air pump installed inside the housing, the housing being provided with an air outlet communicating with the air pump, the air outlet being used to connect to a pneumatic drive device for draining inside the toilet tank.

[0009] Furthermore, in order to enable manual flushing, the toilet tank lid assembly also includes a manual flushing component installed on the lid. The manual flushing component acts on the drain valve inside the toilet tank to open the drain valve when operated.

[0010] Furthermore, to facilitate the supply of power to the electronic control components via mains power, the electronic control components are also connected to an mains power input line, which extends downward along the isolation chamber into the housing and is used to connect to the mains power supply line from the mating chamber.

[0011] Furthermore, in order to power the toilet seat assembly via the electronic control component, the electronic control component is also connected to a toilet seat assembly power supply line, which extends downward along the isolation chamber into the housing and is used to connect to the toilet seat wire from the mating chamber.

[0012] Furthermore, in order to better seal the isolation chamber and the mating chamber, a sealing ring is provided at the position of the isolation chamber for assembly with the mating chamber.

[0013] Furthermore, to facilitate pipeline connection, quick-connect fittings are provided at the ends of the cold water inlet pipe, the hot water outlet pipe, and the communication line extending out of the housing.

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] Example 1

[0022] like Figures 1 to 6 As shown, a toilet tank lid assembly includes: The main body 1 of the water tank cover includes a cover 11 and a housing 12. The cover 11 is fitted onto the upper opening of the housing 12. The housing 12 has an isolation chamber 121 that extends downward and is used to seal and assemble with a mating chamber 3 inside the toilet tank 9. Hot water generation and supply component 2 is installed inside housing 12, with its inlet connected to cold water inlet pipe 21 and its outlet connected to hot water outlet pipe 22. The electrical control component 4 is connected to the hot water generation and supply component 2 and is also connected to a communication line 41; wherein, The cold water inlet pipe 21, the hot water outlet pipe 22, and the communication line 41 extend downwards from the housing 12 along the isolation chamber 121 and are used to connect with the corresponding pipelines from the mating chamber 3.

[0023] Specifically, considering that the electronic control component 4 and the water circuit of the smart toilet are prone to failure, the electronic control component 4 and the water circuit are integrated into the main body 1 of the tank lid, forming a toilet tank lid assembly that can be directly installed on the toilet tank 9. In the event of a failure in the electronic control component 4 or the water circuit, the entire toilet tank lid assembly can be disassembled and replaced directly.

[0024] The toilet tank lid assembly is mounted on the toilet tank 9. In case of a malfunction, lift the tank lid body 1 to disengage the isolation chamber 121 from the mating chamber 3 within the toilet tank 9. Then disconnect the cold water inlet pipe 21, hot water outlet pipe 22, and communication line 41 from the lines within the mating chamber 3 to complete disassembly. During installation, first connect the cold water inlet pipe 21, hot water outlet pipe 22, and communication line 41 of the toilet tank lid assembly to the corresponding lines within the mating chamber 3. Then assemble the tank lid body 1 into the toilet tank 9. During this process, the isolation chamber 121 and the mating chamber 3 achieve a sealed assembly. This allows for the disassembly and assembly of the toilet tank lid assembly and the toilet tank 9. The disassembly and assembly process is simple, convenient, and easy to learn, allowing users to perform it themselves. This solves the problems of high dependence on professional repair personnel, long troubleshooting cycles, inconvenient repairs, and high repair costs associated with mainstream smart toilets.

[0025] In addition, by cooperating with the isolation chamber 121 of the toilet tank lid assembly and the mating chamber 3 inside the toilet tank 9, the pipeline of the tank lid body 1 is isolated from the water inside the toilet tank 9, effectively protecting the pipeline and preventing water inside the toilet tank 9 from seeping or leaking into the housing 12 from the pipeline outlet. This also protects the hot water generation and supply component 2 and the electrical control component 4 located inside the housing 12.

[0026] Furthermore, applying this toilet tank cover component to traditional non-smart toilets can also upgrade the toilet to be intelligent based on ordinary ceramic bodies, and this gravity flushing solution is also more easily accepted.

[0027] The toilet tank lid assembly can be installed on the toilet tank 9 by directly fitting it to the wall of the toilet tank 9, or by adding a foam pad to provide a certain pre-tightening force (the user can simply lift it up to remove it), or by using screws, etc.

[0028] The communication line 41 enables the electronic control component 4 to receive and / or send signals for connection with the toilet seat assembly 8, etc. The cold water inlet pipe 21 is used to connect with the cold water supply pipe entering the mating chamber 3, and the hot water outlet pipe 22 is used to connect with the hot water supply pipe 83 entering the mating chamber 3 of the toilet seat assembly 8.

[0029] In some examples, such as Figure 2 and Figure 3 As shown, the hot water generation and supply component 2 may include an inlet solenoid valve 23, an isolation water tank 24, a water pump 25, and an instant heating unit 26, which are respectively installed in the housing 12 and connected in sequence; wherein, The cold water inlet pipe 21 is connected to the inlet of the inlet solenoid valve 23, and the hot water outlet pipe 22 is connected to the outlet of the instant heating unit 26. The inlet solenoid valve 23, the water pump 25, and the instant heating unit 26 can be powered and controlled by the electronic control component 4. After the electronic control component 4 is triggered by the remote control switch or the corresponding trigger button, the electronic control component 4 controls the operation of the inlet solenoid valve 23, the water pump 25, and the instant heating unit 26.

[0030] It should be noted that the structure of the hot water generation and supply component 2 is not limited to this, as long as it can realize water supply and water heating. The hot water generation and supply component 2 may also include a water inlet solenoid valve 23, a water pump 25 and an instant heating unit 26, which are respectively installed in the housing 12 and connected in sequence.

[0031] In some examples, such as Figure 2 and Figure 6 As shown, the toilet tank lid assembly also includes an air pump 51 installed in the housing 12. The housing 12 is provided with an air outlet 122 that communicates with the air pump 51. The air outlet 122 is used to connect to the drainage pneumatic drive device 52 in the toilet tank 9.

[0032] like Figure 6 As shown, the pneumatic flushing device 52 is installed on the drain valve 54 inside the toilet tank 9. Air is pumped by the air pump 51, causing the pneumatic flushing device 52 to trigger the drain valve 54 to initiate a strong flush. This solves the problem of traditional toilets lacking automatic flushing, enabling automatic flushing and achieving intelligent operation.

[0033] A sensor can be added to the seat ring of the toilet seat assembly 8. When the sensor detects that the user has left, it triggers the electronic control assembly 4 to start the air pump 51. Alternatively, an automatic flush switch can be installed on the side of the toilet. When the user presses the automatic flush switch, it triggers the electronic control assembly 4 to start the air pump 51.

[0034] It should be noted that the automatic flushing configuration is not limited to the air pump 51 and the pneumatic drive device for drainage 52; it can also be triggered by the movement of a rack and pinion driven by a motor.

[0035] In some examples, such as Figure 1 , Figure 2 and Figure 5 As shown, the toilet tank lid assembly also includes a manual flushing component 53 installed on the lid 11. The manual flushing component 53 acts on the drain valve 54 inside the toilet tank 9 to open the drain valve 54 when operated.

[0036] Considering the susceptibility of flushing components to malfunction, a manual flushing component 53 is included; power outages or malfunctions will not affect normal user operation. Figure 1 , Figure 2 and Figure 5As shown, the manual flushing assembly 53 includes a flush button 531 and a flush lever 532. Pressing the flush button 531 causes the flush lever 532 to open the drain valve, thus achieving manual flushing. The structure of the manual flushing assembly 53 is not limited to this; it can also be other structures on non-smart toilets that enable manual flushing.

[0037] In some examples, such as Figure 1 , Figure 3 and Figure 5 As shown, the electrical control component 4 is also connected to an AC power input line 42, which extends downward along the isolation chamber 121 into the housing 12 and is used to connect to the AC power supply line 6 from the mating chamber 3.

[0038] In this way, the electronic control component 4 can be powered by AC mains power. Alternatively, it can be powered by a built-in battery. The electronic control component 4 includes a main control module and a voltage conversion module. The voltage conversion module converts AC mains power into the power supply voltage for the main control module and other electrical components of the toilet, enabling control via the main control module.

[0039] In some examples, such as Figure 1 , Figure 3 and Figure 5 As shown, the electronic control component 4 is also connected to the toilet seat assembly power supply line 43, which extends downward along the isolation chamber 121 into the housing 12 and is used to connect to the toilet seat wire 81 from the mating chamber 3.

[0040] In this way, the toilet seat assembly 8 can be powered through the electronic control component 4. This power supply can power both the seat heater of the toilet seat assembly 8 and the electric flip-top module of the toilet seat assembly 8.

[0041] The entire smart toilet is powered only by the electronic control component 4. If the smart toilet circuit fails, the problem can usually be solved by replacing the entire toilet tank lid assembly.

[0042] In some examples, such as Figure 1 As shown, a sealing ring 1211 is provided at the position of the isolation chamber 121 for assembly with the mating chamber 3. This allows for a better sealed insertion between the isolation chamber 121 and the mating chamber 3, preventing water from entering either chamber. The sealing ring 1211 can be disposed within a sealing ring groove on the outer peripheral wall of the isolation chamber 121.

[0043] In some examples, such as Figure 1 and Figure 5 As shown, quick-connect fittings are provided at the ends of the cold water inlet pipe 21, the hot water outlet pipe 22, and the communication line 41 extending out of the housing 12.

[0044] In this way, the piping on the toilet tank lid assembly can be easily connected to the piping inside the mating chamber 3. Of course, the toilet lid assembly power supply line 43 and the mains input line 42 connected to the electronic control assembly 4 can also be equipped with quick-connect couplings. The piping extending from the mating chamber 3 is also equipped with quick-connect couplings.

[0045] Example 2

[0046] like Figure 4 , Figure 5 and Figure 6 As shown, a smart toilet includes the toilet tank lid assembly described in Embodiment 1.

[0047] like Figure 4 , Figure 5 and Figure 6 As shown, the smart toilet also includes: The toilet body 7 has a wire hole 71 on its end face; The toilet tank 9 is installed on the toilet body 7. It has a mating chamber 3 with a wire hole at the bottom. The toilet tank lid assembly is installed on the upper opening of the toilet tank 9. The isolation chamber 121 of the toilet tank lid assembly is sealed and assembled with the mating chamber 3. The cold water supply pipe 10 enters the mating chamber 3 through the wire hole and is connected to the cold water inlet pipe 21 of the toilet tank lid assembly. The toilet seat assembly 8 is assembled on the toilet body 7. Its toilet seat signal line 82 and hot water supply pipe 83 pass through the wire hole 71 and the wire passage hole into the mating chamber 3, and are respectively connected to the communication line 41 and the hot water outlet pipe 22 of the toilet tank seat assembly.

[0048] This smart toilet allows for easy replacement of the toilet tank lid assembly in case of a malfunction in the electrical control component 4 or the water circuit.

[0049] Communication line 41 is connected to toilet seat signal line 82, and the electronic control module 4 can control the toilet seat assembly 8 to achieve electric lid opening, seat heating, etc. Hot water outlet pipe 22 is connected to hot water supply pipe 83, and hot water generation and supply component 2 can supply hot water to the bidet and feminine wash units on the toilet seat assembly 8. The toilet seat assembly 8 may also have deodorizing and night light units.

[0050] In this embodiment, the toilet seat assembly 8 can be automatically opened and heated by the electronic control module 4 via a remote control switch or a button on the toilet. Alternatively, the electronic control module 4 can be triggered by a sensor to control the toilet seat assembly 8 to automatically open and heat the seat. The communication line 41 of the toilet tank lid assembly can also be connected to some sensors.
