Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of closestool induction, especially to a seat and foot induction system of intelligent closestool. BACKGROUND

[0002] The induction function of the intelligent closestool is an indispensable function, which is used for identifying the use state of the closestool, and then performing intelligent operations such as pre-flushing, hip washing, and seat-flushing. The common induction methods on the market include seat induction sensing and foot induction.

[0003] The seat induction scheme in the prior art is mostly single-point induction, and the induction body is independently integrated in the seat ring. However, it has the following problems: the induction area is very small (about 15 mm in diameter), and the signal is easily lost to cause misoperation when the body moves during sitting; the single-point induction is too sensitive due to the concentrated induction area, and children playing or pets stepping on it can easily cause errors; therefore, the seat induction sensor with multiple-point induction appears on the market, but the setting of multiple-point induction also increases the material and manufacturing costs.

[0004] The foot induction in the prior art is the trend of "non-contact" use of the closestool. Through foot control, intelligent operations such as lid flipping, circle flipping, and flushing can be realized, which improves the convenience and hygiene of the use of the intelligent closestool. The traditional foot control adopts a mechanical or infrared sensing method, which is installed through a hole in the closestool wall. Although the hole area can be maintained, it increases the difficulty of the closestool ceramic body firing process and destroys the overall appearance of the closestool, which is increasingly reduced in the use of medium and high-end products. Microwave radar induction is the development direction of foot induction in recent years. This induction method does not need a hole and directly identifies the foot trigger signal through the ceramic wall, and is increasingly widely applied. However, microwave radar induction is a kind of active sensing, and the inside of the inductor needs to integrate a relatively complex circuit. Once the inductor fails during use, the already installed intelligent closestool needs to be disassembled for replacement and maintenance, which is high in maintenance cost.

[0005] In summary, the current intelligent closestool induction scheme has the problems of low reliability, high production cost, and high maintenance cost. UTILITY MODEL CONTENTS

[0027] The utility model provides a kind of intelligent toilet sitting and foot feeling induction system, it is applied to closestool, closestool includes ceramic base 1 and installs the seat ring 2 of ceramic base 1.

[0028] As Figure 1As shown, the intelligent toilet seat and foot feeling induction system comprises a controller 3, a uniform heating aluminum foil 4 and a sheet-shaped conductive body 5. The controller 3 is a touch sensing controller, which comprises a control chip with a capacitive touch control function and a circuit electrically connected with the chip. The control chip and the related circuit are prior art, and various control chips and circuits in the prior art can realize the functions required by the present application. Therefore, the model of the control chip and the specific structure of the circuit are not described in detail in the present application. The uniform heating aluminum foil 4 is installed in the seat ring 2, and the uniform heating aluminum foil 4 is electrically connected with the detection input end of the controller 3. The controller 3 detects the seat induction signal sent by the uniform heating aluminum foil 4. That is, in the present embodiment, the uniform heating aluminum foil 4 serves as both a component for heating the seat ring 2 and a component for detecting the seat induction signal. The uniform heating aluminum foil 4 is used for two purposes, which can reduce the required components and simplify the structure of the seat ring 2 without the need for additional seat induction components. The sheet-shaped conductive body 5 is installed in the lower region of the ceramic base 1, and the sheet-shaped conductive body 5 is electrically connected with the detection input end of the controller 3. The controller 3 detects the foot induction signal sent by the sheet-shaped conductive body 5. The uniform heating aluminum foil 4 and the sheet-shaped conductive body 5 are both components for recognizing the change of the space capacitance. The controller 3 judges the seat condition and the foot distance by receiving the space capacitance change signal near the two components, thereby providing a basis for judging the user's behavior. The input voltage of the controller 3 is DC 5V, and the output effective signal is low level. After the system is deployed, the sensitivity threshold of the control chip is adjusted by the control software, the suitable use operation experience is set, and the use requirement is met.

[0029] Based on the above structure, the intelligent toilet seat and foot feeling induction system can recognize the seat condition and the foot feeling condition by recognizing the signal change of the uniform heating aluminum foil 4 installed in the seat ring 2 and the sheet-shaped conductive body 5 installed in the lower region of the toilet, and then complete the intelligent control operation.

The connection lead between the uniform heating aluminum foil 4 and the detection input end is connected by riveting, and the connection resistance is less than 100Ω. The riveting part of the uniform heating aluminum foil 4 and the connection lead is coated with a silicone resin sealing layer.

[0031] In the present embodiment, the strength threshold of the seat induction signal of the uniform heating aluminum foil 4 is adjustable, and the signal strength threshold is set by the contact area and weight of the human body, thereby simulating the gravity induction working mode and improving the user's use experience.

[0032] In the embodiment, the sheet conductor 5 is a "sandwich" structure, with a conductive layer in the middle and insulating layers on both sides of the conductive layer. Preferably, the sheet conductor 5 is bonded to the ceramic base 1 by means of back glue, which is convenient to produce by direct bonding and has high flexibility. Of course, the sheet conductor 5 can also be embedded in the ceramic wall of the ceramic base 1 to prevent moisture and insect bites, improve reliability and durability, and at the same time, the lead wire of the sheet conductor 5 is led out of the ceramic wall of the ceramic base 1 for connection with the controller 3. In the embodiment, the area of the conductive layer is 10 cm 2 -200 cm 2 , the insulating layer is a flexible insulating layer, which is convenient to fit with the curved surface of the ceramic body, the ground insulation resistance is greater than 2 MΩ, and the withstand voltage is greater than DC 1500 V.
