[0022] Figure 1 The present invention is a circuit diagram of a wet wipes heating machine. DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , a wet wipes heating machine, comprising:

[0025] The power supply module is used to convert the input AC power into 5V DC power as the working power supply;

[0026] Main control module, used for comprehensive control circuit operation;

[0027] The towel shortage detection module is used to detect whether towels are shortage or not, and to choose whether to feed back voltage signals to the main control module according to whether towels are shortage or not;

[0028] The water shortage detection module is used to detect whether there is water shortage and to choose whether to feed back the voltage signal to the main control module according to whether there is water shortage;

[0029] Temperature detection module, used to detect water temperature and feed back to the main control module;

[0030] The heating control module is used to receive the control of the main control module and drive the heater to heat the water;

[0031] Indicator module, used to indicate whether there is a shortage of water or towels;

[0032] The power supply module is connected to the main control module, the towel shortage detection module, the water shortage detection module, the temperature detection module, the heating control module, and the indication module, and the main control module is connected to the towel shortage detection module, the water shortage detection module, the temperature detection module, the heating control module, and the indication module.

[0033] In a specific embodiment: in the power supply module, an AC power supply (ACL, ACN) is used for input, and the voltage is stepped down to a DC power output of 5V through the AC-DC power chip U1 (3667AH).

[0034] In this example: See Figure 1 The main control module includes chip U4, the model of chip U4 is MC96F8216D, pins 6, 7, and 8 of chip U4 are connected to the indication module, pin 9 of chip U4 is connected to the towel shortage detection module, pin 11 of chip U4 is connected to the water shortage detection module, pin 16 of chip U4 is connected to the temperature detection module, and pin 2 of chip U4 is connected to the heating indication module.

[0035] The main control uses chip U4 (MC96F8216D) to realize analog quantity detection and logic control.

[0036] In this example: See Figure 1 The towel shortage detection module includes an interface CN2, a first end of a first side of the interface CN2 is connected to one end of a resistor R5 and a main control module, a second end of the first side of the interface CN2 is connected to one end of a resistor R4, the other end of the resistor R4 is connected to the other end of the resistor R5 and a 5V voltage, and a second side of the interface CN2 is connected to an optical inspection device to detect whether a towel is missing.

[0037] In the optical inspection device, when a towel is present, the light emitted by the light-emitting tube will be blocked by the towel, and the photosensitive device cannot receive the light; when the towel is not present, there is no towel to block the light, and the photosensitive device receives the light. The photosensitive device chooses whether to be grounded based on whether it receives light, and changes the voltage signal of the first end of the first side and the second side of the interface CN2, and feeds back to the main control module. Figure 1 The feedback signal of the towel-missing detection module is fed back to the main control module through the interface P1, and can also be directly fed back to the main control module.

[0038] In this example: See Figure 1 The water shortage detection module includes an interface CN4, a first end of the first side of the interface CN4 is connected to one end of the resistor R18 and the main control module, a second end of the first side of the interface CN4 is connected to one end of the resistor R19, the other end of the resistor R18 is connected to the other end of the resistor R19 and a 5V voltage, and a second side of the interface CN2 is connected to an optical detection device to detect whether there is a water shortage.

[0039] In the optical inspection equipment, when there is no shortage of water (the water level is sufficient), the light emitted by the light-emitting tube will be obscured by water, and the photosensitive device cannot receive the light; when there is a shortage of water, the photosensitive device receives the light, and the photosensitive device chooses whether to be grounded based on whether it receives light, so as to change the voltage signal of the first end of the first side and the second side of the interface CN4, and feed it back to the main control module.

[0040] In this example: See Figure 1The temperature detection module includes an interface CN3, a first end of a first side of the interface CN3 is connected to a 5V voltage, a second end of a first side of the interface CN3 is connected to one end of a resistor R20 and one end of a resistor R21, the other end of the resistor R21 is grounded, the other end of the resistor R20 is connected to one end of a capacitor C7 and a main control module, the other end of the capacitor C7 is grounded, and a second side of the interface CN3 is connected to a thermistor NTC.

[0041] The water temperature is detected by the thermistor NTC, which changes the voltage signal on the first and second sides of the interface CN3, and is finally fed back to the main control module through the resistor R20.

[0042] In this example: See Figure 1 The heating control module includes a transistor Q1 and a relay RLY1. The base of the transistor Q1 is connected to the main control module through a resistor R15. The emitter of the transistor Q1 is grounded. The collector of the transistor Q1 is connected to the positive electrode of the diode D5 and one end of the relay RLY1. The negative electrode of the diode D5 is connected to the other end of the relay RLY1 and a 5V voltage.

[0043] After receiving the trigger signal from the main control module, the transistor Q1 is turned on, causing the relay RLY1 to turn on and work, controlling the corresponding switch to close, and the heater HEAT is powered on and works.

[0044] In this example: See Figure 1 The indication module includes an interface P1, a first end of a first side of the interface P1 is connected to a 5V voltage, a second end, a third end, and a fifth end of the first side of the interface P1 are connected to the main control module, a second end of a second side of the interface P1 is connected to the anode of the diode LED1, a third end of a second side of the interface P1 is connected to the anode of the diode LED2, a fifth end of a second side of the interface P1 is connected to the anode of the diode LED3, and a cathode of the diode LED1 is connected to the cathode of the diode LED2, the cathode of the diode LED3, and a fourth end of a second side of the interface P1.

[0045] Based on the signals received from the towel shortage detection module and the water shortage detection module and fed back to the main control module, chip U4 changes the output voltage of pins 6, 7, and 8, so that diode LED2 illuminates when there is a water shortage, and diode LED3 illuminates when there is a towel shortage. Under normal circumstances, diode LED1 illuminates. The user can determine whether there is a water shortage or a towel shortage by observing the status of the light-emitting tube.

[0046] Pins 18 and 19 of chip U4 feed back signals to interface CN6, and interface CN6 is connected to an external audio signal to provide voice prompts for lack of water or towels.

[0047] The working principle of the utility model is: the power supply module is used to convert the input alternating current into 5V direct current as the working power supply; the main control module is used to control the operation of the integrated control circuit; the towel shortage detection module is used to detect whether there is a shortage of towels, and choose whether to feed back a voltage signal to the main control module according to whether there is a shortage of towels; the water shortage detection module is used to detect whether there is a shortage of water, and choose whether to feed back a voltage signal to the main control module according to whether there is a shortage of water; the temperature detection module is used to detect the water temperature and feed it back to the main control module; the heating control module is used to receive the control of the main control module and drive the heater to heat the water temperature; the indication module is used to indicate whether there is a shortage of water or towels.

[0048] It is obvious 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 present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
