Description

Technical Field

[0001] Electronic products and smart home products. Background Technology

[0002] Currently, existing tissue boxes are just simple boxes that only serve a protective storage function. They cannot provide weight warnings for the remaining tissues, remind users of the remaining tissue levels, or offer other functions. Summary of the Invention

[0003] To address the problem of not having enough paper when needed, this invention provides a multifunctional tissue box. This tissue box emits an audible alert when the tissue count drops below 20 grams, prompting the user to prepare accordingly. It also features a fragrance spray function to improve the bathroom's air quality, Bluetooth speaker functionality, and a stable 5V output.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: a multifunctional tissue box, including a box body, a main body cover, a small cover for mounting a circuit board integrating a 5.8GHz fixed-frequency radar sensing module (hereinafter referred to as radar module) and an LED light, a perforated cover for fixing an ultrasonic atomizing sheet, a cotton swab, a perfume bottle, three push-button switches, a USB interface with a waterproof cover, a tray, an ultrasonic atomizing sheet, a pressure sensor, a speaker, a battery, a circuit board mainly integrating a chip (hereinafter referred to as MCU) with a Bluetooth speaker chip AC6966 as the main controller, an ultrasonic atomizing sheet driver module, a weighing module, a 3.3V regulated output chip, a power amplifier chip, and a 5V boost chip, and a small box for mounting the integrated circuit.

[0005] As another improvement to the multifunctional tissue box of the present invention, a double-layer partition with a perfume holder is provided inside the main body.

[0006] As another improvement to the multifunctional tissue box of the present invention, a detachable tissue switching base is provided in the tray for holding tissues. When using tissues, the tissue switching base is removed and the tissues can be taken out from under the main body. In order to cope with the change in the base weight after removing the tissue switching base, a sliding switch is added to change the base weight.

[0007] As another improvement to the multifunctional tissue box of the present invention, there are two screw posts in the small cover of the circuit board for installing the integrated radar module and LED light to fix the circuit board.

[0008] As another improvement to the multifunctional tissue box of the present invention, the small box for mounting the circuit board has a round hole with a diameter of about 12.1 mm inside for mounting a push-button switch as the main power switch, and four screw posts with a length of 70 mm and a width of 62 mm. Within the range of these four screw posts, there are also four smaller screw posts for fixing the integrated circuit board.

[0009] As another improvement to the multifunctional tissue box of the present invention, four holes with a rectangular layout of 70mm in length and 62mm in width are provided on the right side of the box body. After the battery and circuit board are installed in the small box for installing the circuit board, the four screw posts with a length spacing of 70mm and a width spacing of 62mm inside the small box for installing the circuit board are aligned with the four holes with the same length and width spacing on the right side of the box body and fixed with screws.

[0010] As another improvement to the multifunctional tissue box of the present invention, a small circular hole is provided on the upper right corner of the main body. The ultrasonic atomizing sheet is covered with a perforated cover, and screws are used to fix the cover around the hole and connect it to the PW interface in the circuit board.

[0011] As another improvement to the multifunctional tissue box of the present invention, a pentagonal hole and four small holes are provided on the right side of the main body for installing the switch button of the main body door and the button for fixing the switch.

[0012] As another improvement to the multifunctional tissue box of the present invention, the right side of the main body is also provided with a rectangular hole and two circular holes with a diameter of about 12.1 mm. The rectangular hole is used to install a USB interface with a waterproof cover, one of the circular holes is used to install a button to control the USB interface to turn on and off, and the other circular hole is used to install a button to control the MCU to enter Bluetooth speaker mode and to pause the alarm sound.

[0013] As another improvement to the multifunctional tissue box of the present invention, in addition to the small annular hole at the bottom of the main body serving as the sound hole for the speaker, there are also four larger circular holes around the outermost ring of the annular hole serving as screw holes for fixing the speaker.

[0014] As another improvement to the multifunctional tissue box of the present invention, a rectangular protrusion is provided at the bottom of the main body, and the protrusion has two screw holes. First, align the two screw holes at the end of the pressure sensor marked with arrows with the two cylinders of the tray and tighten them with screws. Note that the arrows should not point towards the tray. Then, fix the other end to the rectangular protrusion at the bottom of the main body with screws.

[0015] As another improvement to the multifunctional tissue box of the present invention, the VCC, OUT, and GND output pins of the radar module are connected to the 3.3V, ACC, and GND interfaces in the U11 interface on the integrated circuit board via ribbon cables. The ACC interface is connected to the 32nd PA0 pin of the MCU via a line on the integrated circuit board.

[0016] As another improvement to the multifunctional tissue box of this invention, it is also necessary to use C language to program the MCU main control chip. The core logic of the programming effect is: use a while loop or a timer in the MCU to continuously detect the voltage of the PA0 pin. When someone is active, the OUT port of the radar module will send a 3V voltage to the PA0 pin.

[0017] The code `if(IO_PORTA00==1)` is used to make a further judgment, which means that if the pin is high, then the next step of the program will be executed.

[0018] Next, we analyze the data from the sensor. We store the data in a variable named "weight" and write "if (weight < 20)" in the code. This means that when the weight is less than 20 grams, the MCU will automatically proceed to the next step. Here, we can write the code to trigger the announcement sound and also write the code to turn on pin 29, PA3, so that the red LED connected to PA3 lights up. At the same time, we turn on pin 28, PA4, which is connected to the ultrasonic atomizing plate switch module, to achieve the effect of spraying perfume.

[0019] Because the chip used is Jerry's AC6966 Bluetooth chip, the audio file for the alert tone can be downloaded to the chip along with the program code. After specifying the storage path for the audio file, the trigger code for playing the alert tone is written. The chip will then transmit the alert tone signal to the power amplifier module for playback via its 3rd and 4th DACL and DAR pins. The alert threshold can be modified by changing the number 20 in the code.

[0020] With the proactive reminders provided by this invention, users can clearly know the remaining amount of paper towels, thus avoiding the embarrassing situation of running out of paper later, and on the other hand, improving the air quality in the bathroom.

Detailed Implementation Ultrasonic atomizing plate driver module, such as Figure 8 The atomizing plate driver, as shown in the diagram, consists of two 47uF capacitors C40 and C37, a 3.3V Zener diode D1, a 300-ohm resistor R36, a 270kΩ resistor R35, an XKT-255 chip, an AO3400A NMOS transistor Q16, and a 10uH / 500uH three-pin boost inductor connected as shown. Connecting the positive and negative terminals of the ultrasonic atomizing plate arbitrarily to the PW interface, after power-on, the oscillation resistor R35 (270kΩ) controls the output frequency of pin 4 of the XKT-255 to approximately 110kHz. The repeated switching on and off of the NMOS transistor Q16, along with the boost effect of the boost inductor, causes the atomizing plate to generate ultrasonic vibrations, which in turn drive a cotton swab containing perfume to spray perfume and improve air quality. Ultrasonic atomizing plate switch module, such as Figure 8The circuit consists of transistor Q15, PMOS transistor Q14, and resistors R33 (2K ohms), R32 (10K ohms), and R34 (1M ohms). When a high-level signal is received from pin PDCC (PA4) of the MCU (Power Line 28), transistor Q15 turns on. At this time, the voltage across resistor R32 is pulled low, and PMOS transistor Q14 also turns on (its gate is at a low voltage). The 4.2-3.7V voltage from the battery's VCC line flows to the WVDD line through the PMOS transistor. When the MCU's PDCC pin transitions from high to low, the transistor turns off, thus achieving the effect of a high-voltage, high-current circuit switch controlled by the MCU pin. The ultrasonic atomizing driver module, powered by the WVDD line, can then be controlled by the MCU to cut off the current and enter a low-power state when no one is present. The same principle applies to the switching of the weighing module. The MCU's PC5 ZDCC (number 20) controls the switching of the weighing module. When it receives a high level signal from the radar module, it turns on the weighing module and turns it off after the broadcast is complete, thus saving power. The actual radar module is as follows Figure 10 As shown, there are two radar modules, left and right. The left module is shown as the front view, and the right module as the back view. When in use, the back of the module should face the area where people will be active. The three metal holes on the upper left of the right module's back are GND (negative), OUT (output), and VCC (positive). Connect the three interfaces according to... Figure 11 As shown, using Figure 6 The pins 24 in the middle are soldered to ports 1, 2, and 3 of CN2 respectively. The OUT port will eventually be connected to pin 32 PA0 of the MCU of the integrated circuit through a wire and then it can start to work normally. Its detection range is about 6 meters in a 180° radius. When someone moves within this range, the OUT port will generate a 3V voltage to the MCU for about 1 second. Weighing module such as Figure 8As shown, the four wires of the pressure sensor—power positive, signal negative, signal positive, and power negative—are connected to pins 1, 2, 3, and 4 of the U8 terminal block, respectively. The circuit design between the pressure sensor and the HX711 analog-to-digital converter chip uses a common circuit provided by the HX711 manufacturer, consisting of resistors R12 (20K ohms), R17 (8.2K ohms), R3 (1K ohms), capacitors C26 (100NF), C4 (1µF), C10 (1µF), C15 (100NF), and transistor Q4 (SS8550). The power supply is 3.3V from the DCC output of pin 18 of the MCU. Normally, when the pressure sensor senses pressure, it transmits the generated analog signal to the HX711 chip. The chip automatically converts the analog signal into a digital signal, which is then connected to the MCU via the OUDA and SCK wires, transmitting the digital signal to the MCU. Power amplifier module such as Figure 8 The amplifier chip is labeled as follows: U3 is the MIX8911 amplifier chip, and it consists of a 10uF capacitor, 1uF capacitors C42 and C44, a 4.7uF capacitor C7, 470uF capacitors C5 and C13, 100NF capacitors C8 and C45, a 0-ohm resistor R48, and 20k ohm resistors R49 and R50. The audio signal from the MCU is transmitted to the amplifier via the DACL and DAR lines. After being amplified by the amplifier, it is played back by the speaker connected to pins 8 and 9 of the amplifier chip. Main control chip MCU such as Figure 8 As shown, the main control chip MCU of this invention includes, but is not limited to, the AC6966 chip. Pin 32 (ACC) is connected to the microphone module; pins 7 (OUDA) and 8 (SCK) are connected to the weighing module, where pin 7 receives weight data and pin 10 is the clock signal line between them; pin 26 (PA6 HOLD) is used to connect to the button switch, which calculates the voltage and number of times the button is pressed to switch between mute and Bluetooth modes; pins 29, 5, and 6 are connected to and control the red, blue, and white LEDs to blink on and off when there is not enough tissue, in Bluetooth mode, and in normal mode; pins 24 and 25 are ports used for program download. USB 5V boost module, such as Figure 8 As shown, the circuit consists of a PS7516 chip, 100 nanofarad C38 and C41, 10 microfarad C35, 22 microfarad C36, 523K ohm resistor R37, 100K resistor R38, and 10 microfarad boost inductor L2. When the button for controlling the USB switch connected to the CN17 interface is pressed, current from the battery VCC flows into the PS7516 chip, and then the boost chip automatically boosts the voltage to 5V. The current then flows to the USB interface connected to CN18, thus providing a 5V voltage to the outside. USB port mounting location with a waterproof cover. (Example) Figure 2 As shown, the rectangular hole 10 on the side of the main body 35 is 21 mm long and 9.8 mm wide. This is where the USB interface is installed; simply push it in firmly. Install buttons to control the USB switch, as well as buttons to enter Bluetooth speaker mode and mute, such as... Figure 2 As shown, two 12.1mm diameter circular holes 11 and 12 are fixed to the side of the main body 35. The switch is connected to... Figure 8 The CN13 interface has one end connected to pin 26 (PA6) of the MCU via a HOLD line, and the other end is grounded. The program determines the number of times a button on the CN13 has been pressed within a certain time frame by counting the voltage changes that connect to the negative terminal. The program code sets that double-pressing activates Bluetooth speaker mode, while a single click triggers a mute tone. The button types and shapes are as follows... Figure 20 As shown, this is a 12mm diameter push-button switch with a threaded nut. Simply insert the switch into the mounting hole and tighten the nut from the back to secure it. Bluetooth speaker function, after entering Bluetooth mode, the chip communicates via... Figure 8 As shown, the antenna U2 connected to pin 17 broadcasts a signal with the Bluetooth name. After the mobile phone connects to this signal, all the sounds played on the mobile phone will be automatically transmitted to the chip through this signal. The audio decoding circuit inside the chip decodes the audio information and transmits the audio information to the power amplifier module through pins 3 and 4 for playback, thus realizing the Bluetooth speaker function. like Figure 7 As shown, the USB interface has been fitted with a white waterproof cap, which adds a waterproof function compared to other traditional USB interfaces, preventing water from entering the interface and causing a short circuit in the entire circuit. The 3.3V output voltage regulator chip is model ME6211C33M5G-N. Figure 8 As shown, pin 1 is its voltage input terminal, pin 5 is its voltage output terminal, and the parallel capacitor can act as a filter. When the battery voltage is input, it can stabilize the voltage at 3.3 volts through its internal circuit structure. The output voltage of 3.3 volts is used to provide a stable voltage for the button voltage acquisition and calculation of pin 26 PA6 of the main control chip MCU, as well as the power supply for the atomizing plate switch module and the aforementioned radar module. Battery connection as follows Figure 8As shown in the battery charging management diagram, the positive terminal of the battery is connected to pin 1 of the CN4 interface, and the negative terminal is connected to pin 2. Battery charging is achieved by outputting a USB 5V voltage from the TYPE-C interface to pin 4 (VCC) of the LTC4054 chip. After voltage reduction and current limiting by the chip, the voltage flows from pin 3 of the chip to the positive terminal of the battery. The diagram also shows that when there is no battery, inserting the charging cable into the TYPE-C interface allows power to flow through diode U7 (SS34) into the VCC circuit, supplying power to the entire circuit. The battery's push-button switch is connected to Figure 8 When the switch is pressed, pins 1 and 2 of the CN8 interface are turned on. The positive current from the battery at pin 1 of CN4 flows through the Schottky diode U7 SS34 and then through pin 2 of CN8 to the VCC circuit to power the entire circuit. An LED can be connected between pin 3, which is connected in series with pin 2, and pin 4, which is grounded, as a power indicator. like Figure 19 As shown, each side of the tray 1 has a small cuboid extending out, which serves as a slot 32 for placing the tissue paper switching base. When the tissue paper switching base 16 is placed, the slot 32 secures it, and the tissue paper switching base 16 blocks the gap in the middle of the tray 1. To remove the tissue paper switching base, it is removed through the cutout 33. Tray tissue paper guide plates 1.1 are also provided on both sides below the gap in the middle of the tray 1 to prevent the tissue paper from getting stuck in the gap when it passes downwards through the tray 1 and the main body 35. like Figure 8 As shown, pin 22 of the MCU is also connected to a slider switch U9. When the switch is slid to the 3.3V end, meaning a 3.3V current is drawn to pin 22, the voltage at that pin is high. Because removing the tissue box switching base 16 will cause the pressure sensor 2 to generate a new value due to pressure changes, a check needs to be added to the program: when pin 22 is high, the new value is used as the base value for calculating the weight and saved to the MCU. This way, removing the tissue box switching base 16 will not affect the subsequent weight calculation. like Figure 21 , 22 As shown, there is a guide sleeve 20.3 below the main door switch button fixing bracket 20, which can restrict the movement trajectory of the main door switch button 14 after it is opened by the spring. In addition, there are spring posts 14.1 below the main door switch button, spring posts 20.1 below the main door switch button fixing bracket, and hook buckles 14.2 below the main door switch button for hooking onto the same hook buckles on the main cover 19 to achieve the goal of tightening the main cover 19. There are four screw holes 20.2 below the main door switch button fixing bracket to firmly fix the bracket to the main body 35. Overall assembly steps: The first step is to install the speaker in such a location. Figure 2 The main body is shown at position 13 on the bottom, and is secured around the perimeter with screws and nuts. Then, according to... Figure 3 The diagram shows the positional relationship between pressure sensor 2, tray 1, and main body 35. First, connect the suspended end of pressure sensor 2 (generally, the end with the arrow pointing downwards, as marked by the manufacturer) to the two screw posts below tray 1 (the arrangement of screw holes varies depending on the manufacturer and the precision of the sensor; the position of the screw posts should be adjusted accordingly) indicated by the red arrows, and tighten the screws in the direction of the arrows to secure them. Then, according to... Figure 2 As shown, on the rectangular protrusion 3 at the bottom of the tissue box body 35, use screws 15 to align the two screw holes at the other end of the pressure sensor 2 with the rectangular protrusion 3 with two holes on the right side of the bottom of the box, in the direction of the arrow. The second step is as follows: Figure 4 , Figure 5 As shown, a lid 5 with a small circular hole about 1 cm in diameter is used to cover the ultrasonic atomizing plate 8 at the upper left corner of the box, specifically at the position 9 with the small circular hole. Screws are then used to secure the lid 5 around its perimeter, thus fixing the ultrasonic atomizing plate to the side of the box. The perfume bottle 6 is placed on the second shelf 4 of the tissue box, and a cotton swab inserted into the perfume bottle 6 connects the perfume to the ultrasonic atomizing plate 8. The third step is as follows: Figure 18 The bottom of box 7 has a rectangular hole for threading wires for various components. Then, the battery connected to the integrated circuit is attached to the back of the integrated circuit using double-sided tape. With the integrated circuit facing down, align the four holes around the integrated circuit with the screw posts 29 inside the small box and tighten the screws to secure it. Install the power switch in the round hole 30 of the small box. Further, connect the two switches installed in positions 11 and 12 to the integrated circuit via wires, and then connect the wires of other components such as the pressure sensor. Align the longer screw post 21.1 inside with the hole 21 on the right side of the main body 35 and tighten the screw and nut. The small box is now fixed in place. Step 4 Figure 2 Above the USB mounting hole 10, there is a pentagonal hole. After passing the main body door switch button 14 through this hole from inside the main body 35 outwards, a spring is placed on each of the two spring posts 14.1 below the main body door switch button. Then, according to... Figure 21 As shown, the other ends of the two springs are respectively fitted onto the spring posts 20.1 below the main body door switch button fixing bracket, and then screws and nuts are tightened into the screw holes 20.2 below the main body to secure them. The fifth step is to align the holes of the integrated radar module and LED light circuit. Figure 12 Then tighten the screws on the small and medium-sized caps, screwing in the screws on the 18 screw posts and 27 screws. Figure 16As shown, first align the lampshade 17 with the screw post of the main body cover 19 and fasten it, then align the small cover 18 with the screw of the main body cover 19 and fasten it, then tighten the screw. After the main body cover 19 is inserted into the pivot 31 of the main body 35, pass the wires connecting the radar module and LED circuit board and integrated circuit through the bottom of the tray 1, and then press the power switch to start working. The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
