Description

Technical Field

[0001] This utility model relates to fault detection equipment, and in particular to a detection device for a foam shield in a smart toilet. Background Technology

[0002] Currently, troubleshooting malfunctions of the foam shield function in smart toilets on the market requires after-sales personnel to manually unscrew the drain cap at the bottom of the seat to drain the foam liquid before turning the seat over to disassemble the mechanism. After disassembling the mechanism, the power must be re-energized, and professional instruments such as multimeters must be used to measure each component of the foam shield to determine which part is damaged. The drain cap of the foam shield is located at the bottom of the seat and is difficult to unscrew without special tools, and it is also difficult to tighten properly, which can easily cause leakage. During the drainage process, the seat needs to be shaken to drain the foam liquid completely, which can easily damage and scratch the seat, causing losses. If the liquid is not drained completely, turning the seat over can cause the foam liquid to wet the internal electronic components, making it impossible to clean and damaging the seat, resulting in significant losses.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] This utility model relates to a detection device for a foam shield in a smart toilet, comprising a drain pump 100, a detection mechanism, a control mechanism, and a display mechanism 200.

[0033] like Figure 1 As shown, the drain pump 100, detection mechanism, control mechanism, and display mechanism 200 can all be mounted on a single chassis. The drain pump 100 includes a suction end 101 and a discharge end 102, which can be connected to infusion tubing, etc. The detection mechanism is used to pair with electrical components in the foam shield to be tested. These components include a suction pump, an air pump, an air-liquid mixing mechanism, and a liquid level detection mechanism, the specific configuration depending on the actual model of the foam shield. The detection mechanism detects whether any electrical components in the foam shield are faulty, generating a feedback signal after detection. The control mechanism includes a control chip IC1, which is connected to the drain pump 100 and the detection mechanism. The control mechanism controls the start and stop of the drain pump 100 and the detection mechanism. Simultaneously, the control chip receives the feedback signal from the detection mechanism. The display mechanism 200 is connected to the control chip, which outputs the feedback signal to the display mechanism 200, displaying the detection results for each electrical component.

[0034] In actual use, when the foam shield device on the smart toilet malfunctions, the maintenance personnel connect a flexible hose to the suction end 101 of the drain pump 100, extending the hose into the liquid storage chamber of the foam shield. The drain pump 100 is then started to extract the foam liquid from the storage chamber and discharge it through the drain end 102 of the drain pump 100 into an external container for temporary storage. The detection mechanism is then connected to the electrical components in the foam shield via wires. After power is applied, the current detected by the detection mechanism for each electrical component is converted into a voltage feedback signal, and the detection results are finally displayed through the display mechanism 200. Based on the displayed results, the maintenance personnel can then disassemble and replace the electrical components in the foam shield accordingly. The detection device for foam shields in smart toilets of this invention eliminates the need to remove the drain cover at the bottom of the smart toilet seat. The foam liquid in the storage cavity is quickly drained by extraction, effectively preventing scratches or damage to the cover when removing it. At the same time, the detection mechanism, control mechanism and display mechanism 200 work together to quickly detect faulty electrical components, greatly improving maintenance efficiency.

[0035] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the detection mechanism includes a first detection module. The first detection module includes a current sensing amplifier U2, a first interface CN1, a diode D1, resistors R1, R2, R3, and R4, a PMOS transistor Q2, a capacitor C1, and a transistor Q1. The first interface is used to connect to the electrical device under test. The electrical device detected by the first detection module is mainly the liquid pump or air pump of the foam shield. Diode D1 is connected in parallel with the first interface, and the positive terminal of diode D1 is grounded. The two ends of resistor R4 are connected to the RS+ and RS- pins of the current sensing amplifier, respectively. The end of resistor R4 connected to the RS- pin is connected in series with the negative terminal of diode D1, and the end of resistor R4 connected to the RS+ pin is connected to the PMOS transistor Q2. The output terminal of the current sensing amplifier is connected to one of the receiving pins of the control chip; in this example, the output terminal of the current sensing amplifier is connected to the AD5 pin of the control chip. Resistor R1 and capacitor C1 are connected in parallel with PMOS transistor Q2. Resistor R2 is connected between the collectors of PMOS transistor Q2 and transistor Q1. Resistor R3 is connected between one of the pins of the control chip and the base of transistor Q1. In this example, resistor R3 is connected to pin AD3 of the control chip. The emitter of transistor Q1 is grounded. During testing, the foam shield's pump or air pump is connected to the first interface CN1 via a wire. The output voltage of pin AD3 of the control chip controls transistor Q1 to conduct, and PMOS transistor Q2 also conducts. The 12V voltage flows through resistor R4 and the pump or air pump to form a circuit. The current sensing amplifier U2 detects the current in resistor R4 and converts it into a voltage signal, which is output to pin AD5 of the control chip. The control chip determines whether the pump is functioning properly by checking whether the voltage at AD5 matches the internally set pump voltage.

[0036] Furthermore, the testing mechanism includes at least two first testing modules. Each first testing module is paired and connected to the electrical device under test through a corresponding first interface. Multiple first testing modules can be connected to electrical devices such as the liquid pump and air pump of the foam shield. After each first testing module is powered on, it performs synchronous testing on the liquid pump, air pump, and other electrical devices. Then, the current detected by each module is converted into a voltage signal and output to the control chip. Finally, the testing results of each first testing module are displayed through the display mechanism 200.

[0037] In some specific embodiments of this utility model, such as Figure 2 and Figure 4As shown, the testing mechanism also includes a second testing module. The second testing module includes a second interface CN3, resistors R9, R10, R11, and R12, a transistor Q5, and a capacitor C4. The second interface includes a first terminal and a second terminal. The first terminal is connected in series with resistor R12. Resistor R11 and capacitor C4 are connected in parallel in the connection circuit between the first terminal and resistor R12. The connecting wire between resistor R11 and capacitor C4 is grounded. Resistor R12 is connected to pin AD2 of the control chip. The second terminal is connected to the emitter of transistor Q5, and resistor R9 is connected to the collector of transistor Q5. Resistor R10 is connected between pin AD1 of the control chip and the base of transistor Q5. The output voltage of pin AD1 of the control chip controls the conduction of transistor Q5. In actual testing, the first and second terminals of the second interface are connected to probes respectively. The probes are inserted into the liquid storage cavity of the foam shield. Voltage flows from the probe at the second terminal contacting the liquid, forming an electrical conduction, to the probe at the first terminal for output. The control chip determines whether the liquid level is normal by checking whether the voltage at pin AD2 matches the internally set liquid level voltage.

[0038] Based on the above embodiments, if the electrical components detected by the first detection module and the second detection module are both normal, but the foam shield still does not work properly, then the liquid pump, air pump, and liquid level detection can be ruled out as faulty electrical components, and it can be determined that the gas-liquid mixing mechanism of the foam shield is faulty.

[0039] Among them, such as Figure 1 As shown, the control mechanism also includes a first button 301, which controls the start of the detection mechanism. The first button 301 can be a mechanical button or a touch button, etc. The first button 301 is used to quickly control the start of the detection mechanism. The control mechanism also includes a second button 302, which can be a mechanical button or a touch button, etc. The second button 302 is used to control the start and stop of the drainage pump 100.

[0040] The display mechanism 200 can be configured for a light display mode. For example, multi-color LEDs can be connected to the control mechanism; if a fault is detected in an electrical component, the LEDs will display red; if the component is functioning normally, the LEDs will display green, and so on. In this embodiment, the display mechanism 200 includes a display screen. The display screen is connected to the control chip. The display screen directly displays which electrical component is malfunctioning through text or images.

[0041] In some specific embodiments of this utility model, a buzzer mechanism 400 is also included. The buzzer mechanism 400 includes a horn. The buzzer mechanism 400 is connected to the control mechanism. When the detection mechanism detects a faulty electrical component, the buzzer mechanism 400 emits an alarm sound to notify the maintenance personnel that the inspection has been completed and the fault has been found.
