Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to an automatic toilet flushing device based on wireless transmission. Background Technology

[0002] Currently, toilets in older residential areas and public places mostly use traditional mechanical transmission structures, requiring users to manually press or step on buttons to control flushing. This operation is cumbersome and easy to forget, leading to unpleasant odors and bacterial growth in the bathroom.

[0003] Therefore, existing old-fashioned toilets need to be upgraded to smart toilets with automatic flushing control. However, there are two options for the upgrade: First, replace the ceramic base, water tank, and toilet seat as a whole, but this is costly and the disassembly and assembly process can easily damage the original bathroom decoration; Second, replace the toilet seat with a smart toilet seat with flushing control function. This type of smart toilet seat needs to be connected to the drain valve and external power supply via wires, which is not suitable for bathrooms without sockets and makes it difficult to achieve a convenient upgrade of old facilities. Utility Model Content

[0004] This utility model provides an automatic toilet flushing device based on wireless transmission. It features a simple structure, easy installation, and low cost. It primarily addresses the problems of high retrofitting costs for older toilets and power constraints when replacing them with wired smart toilet seats. The main technical solution adopted is as follows:

[0005] An automatic toilet flushing device based on wireless transmission includes a wireless control device for sending action signals to control flushing. The wireless control device can be a wireless remote control and / or a smart toilet seat with sensors. A wireless transceiver is installed on the wireless control device and electrically connected to it. The transceiver receives the action signals and converts them into electrical signals for transmission. An electrically controlled drain valve, installed on the toilet, includes a wireless controller and a drain valve electrically connected to each other. The wireless controller is connected to the wireless transceiver via a wireless signal and receives the electrical signals emitted by the transceiver, converting them into action signals and sending them to the drain valve. The drain valve has a mechanical trigger, and the flushing action can be performed by manually driving the mechanical trigger or by receiving action signals from the wireless controller.

[0006] Preferably, the sensor of the smart toilet seat is a seat sensor, which is embedded in the toilet seat ring of the smart toilet seat and electrically connected to a wireless transceiver to detect the unseat state of the toilet seat ring and trigger the action signal.

[0007] Preferably, the seat sensor is a capacitive sensor or a pressure sensor, which is used to detect the seated and unseatped states of the toilet seat.

[0008] Preferably, the housing of the wireless remote controller is embedded with a button unit, which is electrically connected to the wireless transceiver to manually control the button unit to trigger the action signal.

[0009] Preferably, the wireless control device and the electrically controlled drain valve include an MCU chip.

[0010] Preferably, both the wireless control device and the electrically controlled drain valve are equipped with batteries for power supply; the wireless transceiver is electrically connected to the wireless control device via a wire; and the wireless controller and the drain valve are electrically connected via a wire.

[0011] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0012] (1) This utility model provides an automatic toilet flushing device based on wireless transmission. It has a simple structure, is easy to install, easy to implement, and has a low cost. It mainly solves the problems of high cost of retrofitting old-fashioned toilets and power constraints when replacing wired smart toilet seats. The technical solution of this utility model uses an electric drain valve and a wireless control device as a matching combination product to retrofit old-fashioned toilets. It does not require replacing the entire toilet. The retrofit can be completed by replacing only the drain valve and the toilet seat, which greatly reduces the cost. At the same time, the wireless transmission design can get rid of the constraints of wired wires and is extremely suitable for bathrooms without reserved sockets. Secondly, it also supports automatic wireless control and manual mechanical flushing, ensuring that it can still be used normally in the event of power failure or malfunction, thus improving reliability.

[0013] (2) In this technical solution, the seat sensor is selected as the sensor source of the toilet. When it is embedded in the toilet seat of the smart toilet seat, it can directly detect the user's state of leaving the seat. The sensing position is more accurate, the triggering action signal is more reliable, and false triggering is avoided. Attached Figure Description

[0026] Please see Figures 1 to 2 .

[0027] This embodiment provides a wireless transmission-based automatic toilet flushing device, which is simple in structure, easy to install, easy to implement, and low in cost. It mainly solves the problems of high retrofitting costs for existing old-style toilets and power constraints when replacing wired smart toilet seats 11. This utility model includes a wireless control device 1 and an electrically controlled drain valve 212; wherein...

[0028] The wireless control device 1 in this embodiment is mainly used to send action signals to control flushing. The wireless control device 1 is a wireless remote control and / or a smart toilet seat 11 with a sensor. Both the remote control and the smart toilet seat 11 are equipped with a wireless transceiver 1A.

[0029] In this embodiment, a seating sensor is embedded inside the toilet seat ring of the smart toilet seat 11. This seating sensor is primarily a capacitive sensor or a pressure sensor, either of which can be used to detect the seat's insertion and removal status. A wireless transceiver 1A is disposed on the toilet seat ring or on the toilet seat cover 11, and the sensor is electrically connected to the wireless transceiver 1A via a wire. A battery is provided on the toilet seat ring or cover to power the sensor and the wireless transceiver 1A.

[0030] In this embodiment, when the sensor is a pressure sensor, the pressure sensor is embedded in the core force-bearing area of ​​the toilet seat. After the user sits down, the toilet seat is subjected to force, and the sensor detects the pressure change and continuously monitors it. When the user gets up, the pressure disappears and triggers an action signal to get up. This action signal is directly transmitted to the wireless transceiver 1A through a wire.

[0031] If the sensor is a capacitive sensor, it is placed on the toilet seat. When the user sits down and approaches the toilet seat, the capacitive sensor will sense the change in capacitance and continuously monitor it. When the user gets up, the capacitance value drops rapidly, and the sensor triggers the get-up action signal.

[0032] In this embodiment, a button unit is embedded in the shell of the wireless remote control. The button unit is electrically connected to the wireless transceiver 1A. That is, the bottom of the button unit is provided with a metal spring contact. The contact is connected to the GPIO interface of the wireless transceiver 1A through a terminal block via a tin-plated wire. When in use, the button is manually pressed to trigger an on / off action signal. The action signal is transmitted to the wireless transceiver 1A through a wire.

[0033] In this embodiment, the wireless transceiver 1A includes a wireless transceiver circuit (using 2.4GHz Wi-Fi) and an MCU chip 10. The wireless transceiver circuit and the MCU chip 10 are electrically connected through copper foil traces on the PCB board to ensure stable high-frequency signal transmission. After receiving an action signal through the wireless transceiver circuit, the wireless transceiver 1A converts the action signal into an electrical signal through its internal signal conversion circuit (located on the PCB board) and then transmits it to the MCU chip 10. The MCU chip 10 can perform actions such as parsing and verification on the electrical signal to confirm the accuracy of the data. When the data is confirmed to be correct, the wireless transceiver circuit activates the wireless transmission function to transmit the corresponding action signal wirelessly. If the data is confirmed to be incorrect, the received data is discarded and no output is performed.

[0034] The electrically controlled drain valve 212 of this embodiment is mainly installed inside the toilet body, i.e., on the ceramic body. The electrically controlled drain valve 212 includes a wireless controller 2A and a drain valve 21 electrically connected to each other via wires. The wireless controller 2A in the electrically controlled drain valve 212 also includes a wireless transceiver circuit and an MCU chip 20. The wireless transceiver circuit and the MCU chip 20 are rigidly electrically connected via copper foil wires on the PCB board. After receiving the action signal from the wireless control device 1 via the wireless transceiver circuit, the wireless controller 2A converts the action signal into an electrical signal through its internal signal conversion circuit and then transmits it to the MCU chip 20. The MCU chip 20 can perform actions such as parsing and verification of the electrical signal to confirm the accuracy of the data. When the data is confirmed to be correct, the MCU chip 20 directly sends the corresponding action signal to the drain valve 21 via the wires to perform the flushing action. If the data is confirmed to be incorrect, the received data is discarded and no output is executed, and the drain valve 21 does not work.

[0035] The working principle and usage process of this utility model:

[0036] In this embodiment, the electrically controlled drain valve 212 and the wireless control device 1 are mainly used as a complementary combination device to retrofit old-style toilets. In actual retrofitting... Figure 1 When using an old-fashioned toilet,

[0037] First, the original mechanical drain valve 21 in the water tank 42 behind the ceramic body 41 is removed and replaced with an electrically controlled drain valve 212 with a wireless controller 2A as described in this embodiment. This electrically controlled drain valve 212 has one thing in common with the traditional mechanical drain valve 21: both have a mechanical trigger part (not shown in the figure). This mechanical contact part is the flushing press switch of the drain valve 21. By pressing the switch, the drain valve 21 can be made to work to realize mechanical transmission drainage.

[0038] Next, the old toilet seat 11 is completely removed and replaced with a smart toilet seat 11 equipped with a wireless transceiver 1A. A wireless remote control with a wireless transceiver 1A can also be provided as needed; this completes the toilet modification. In this embodiment, the smart toilet seat 11 has functions such as disinfection and bidet washing. The modified toilet can directly replace the existing smart toilet and also has a wireless flushing function, solving the shortcomings of existing smart toilets that require wired connection and can only be flushed manually by pressing or kicking the flush switch.

[0039] The usage procedure for the modified toilet: See [link / reference] Figure 2 When a user sits on the toilet seat, the toilet's sensor (using a pressure sensor) detects the pressure applied to the seat. After the user leaves the seat, the sensor triggers an action signal based on the pressure change. This action signal is then transmitted via a wire to the wireless transceiver circuit of the wireless transceiver 1A. The internal signal conversion circuit of the wireless transceiver 1A converts the action signal into an electrical signal and transmits it to the MCU chip 10. After confirming that the electrical signal is correct, the MCU chip 10 transmits the action signal to the electrically controlled drain valve 212.

[0040] At this time, the wireless controller 2A in the electrically controlled drain valve 212 receives the action signal from the wireless control device 1 through the wireless transceiver circuit. The signal conversion circuit inside the wireless controller 2A converts the action signal into an electrical signal and then transmits it to the MCU chip 20. After confirming that the electrical signal is correct, it transmits the action signal to the drain valve 21, and the drain valve 21 opens to perform the flushing action. If the user finds that one flush is not enough to clean the drain, see [link to relevant documentation]. Figure 2 The flushing process can be repeated more than once by manually pressing the button on the wireless remote control (if equipped). In the absence of power, such as when the rechargeable battery on the electrically controlled drain valve 212 is de-energized, the user can still flush the toilet by manually pressing the mechanical trigger. Therefore, this invention is simple in structure, easy to install, easy to implement, and low in cost. It mainly solves the problems of high cost of retrofitting existing old-style toilets and power constraints when replacing the wired smart toilet seat 11. The technical solution of this invention uses the electrically controlled drain valve 212 and the wireless control device 1 as a complementary combination to retrofit old-style toilets. It eliminates the need to replace the entire toilet; only the drain valve 21 and the toilet seat 11 need to be replaced, significantly reducing costs. Simultaneously, the wireless transmission design eliminates the constraints of wired cables, making it extremely suitable for bathrooms without pre-installed sockets. Furthermore, it supports both automatic wireless control and manual mechanical flushing, ensuring normal operation even in the event of power outages or malfunctions, thus improving reliability.

[0041] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
