Description

Technical Field

[0001] The utility model relates to the technical field of sterilization devices, and in particular to a sterilization device for a wirelessly powered kitchen waste food processor. Background Art

[0002] Nowadays, the country has begun to pay attention to the classification and treatment of kitchen waste. There are also waste food processors used in kitchen sinks. Food residues can be poured directly into the kitchen sink. After being crushed by the waste food processor, the food residues are discharged through the sewer pipe or collected and stored. The waste food processor can effectively crush food kitchen waste to avoid garbage blockage or storage inconvenience.

[0003] Regardless of whether food waste is crushed or not, it will deteriorate, mold, and stink in the sewer pipes or collection storage devices, increasing secondary environmental pollution. It is also easy to breed bacteria and viruses and become a source of disease transmission.

[0004] Although the food waste disposer crushes food waste into particles and discharges them into the sewer pipe with water flow, and although a large amount of drainage and flushing is helpful to inhibit the growth of bacteria, residual impurities will inevitably remain on the inner wall of the cavity to produce bacteria and odor.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0048] like Figure 1-4 As shown, a specific embodiment of the utility model provides a sterilization device for a wirelessly powered kitchen waste food processor, including: a housing, a base, a wireless induction receiving control circuit board 3, a receiving coil 4, a sterilization device, a wireless induction transmitting control circuit board 6, and a transmitting coil 7;

[0049] The housing comprises: a top cover 11 and a top shell 12; the top cover 11 is a round cover; the top shell 12 is barrel-shaped, with only the top end open; the top cover 11 covers the top of the top shell 12; the housing can be used as a plug to be inserted into the feed inlet 8 of the waste food processor along the axial direction until it reaches the entrance of the crushing chamber of the waste food processor;

[0050] The top cover 11 is a round cover, and a groove 13 for placing the receiving coil 4 is axially provided on the edge of one side of the top cover 11 facing the top shell 12; the receiving coil 4 is placed in the groove 13 of the top cover 11 and fits with one side wall of the groove 13; the receiving coil 4 is a single metal wire wound in a concentric radial extension manner or in a coaxial equal-diameter axial extension manner, such as Figure 3 As shown, a single-layer ring-shaped stack is formed;

[0051] The wireless induction receiving control circuit board 3 can be embedded in the side of the top cover 11 facing the top shell 12, or can be placed in the cavity of the shell together with the sterilization device; the sterilization device takes the ultraviolet lamp 51 as an example, and the sterilization device includes: an ultraviolet lamp 51 and a lampshade 52; the sterilization device control circuit includes: an ultraviolet lamp 51 control circuit; a through hole for installing the lampshade 52 is opened at the bottom of the shell, and the lampshade 52 is sealed and installed on the through hole; the ultraviolet lamp 51 is assembled with the lampshade 52 in a manner of irradiating in the direction of the lampshade 52, and the ultraviolet lamp 51 can irradiate into the crushing cavity of the waste food processor, and sterilize by irradiation of the ultraviolet lamp;

[0052] The wireless induction receiving control circuit board 3 includes: a wireless induction receiving circuit and a sterilization equipment control circuit; the receiving coil 4 is connected to the wireless induction receiving circuit; the wireless induction receiving circuit is connected to the sterilization equipment control circuit; the sterilization equipment control circuit is connected to the sterilization equipment circuit;

[0053] The base 2 is annular, and the inner wall of the base 2 is in the shape of a tooth. Two fixing members 22 opposite to each other can be used. The fixing members 22 are radially screwed in to achieve sleeve engagement with the outer wall of the inlet 8 of the waste food disposer. The base 2 can be engaged with the outer wall of the inlet 8 of the waste food disposer. A groove 21 is formed in the axial direction on one end surface of the base 2.

[0054] The wireless induction transmission control circuit board 6 and the transmitting coil 7 are placed in the groove 21 of the base, and the insulating sealant can be injected into the groove 21 of the base 2 to fix the wireless induction transmission control circuit board 6 and the transmitting coil 7;

[0055] The transmitting coil 7 is coaxially arranged with the base 2, and the transmitting coil 7 is in contact with the wall of the groove 21 on the inner side of the base 2. The transmitting coil 7 is a single metal wire wound in a coaxial equal-diameter axially extending manner;

[0056] The wireless induction transmission control circuit board 6 includes: a wireless induction transmission control circuit and a switch control circuit; the wireless receiving control circuit is connected to the transmitting coil 7; the switch control circuit controls the working state of the wireless induction transmission control circuit;

[0057] like Figure 4 As shown, the shell is inserted into the food inlet 8 of the waste food processor, and the engaging position of the base 2 needs to make the receiving coil 4 and the transmitting coil 7 within the same height range. The setting height of the receiving coil 4 and the transmitting coil 7 is based on the ability of the receiving coil 4 and the transmitting coil 7 to transfer energy when in use, that is, when assembled and used, the receiving coil 4 and the transmitting coil 7 must have at least an overlapping area.

[0058] The existing wireless induction power supply coil is generally wound by using a single coil concentrically and radially wound in circles at both the transmitting end and the receiving end, similar to a mosquito coil. If the existing wireless induction power supply device is used, the transmitting end coil can only be arranged on one side of the waste food disposer. When in use, the receiving end coil must be accurately aligned with the transmitting end coil arranged on one side of the waste food disposer, otherwise power supply cannot be achieved, which requires high operating accuracy and does not meet the simplicity requirements of daily use.

[0059] The winding method of the transmitting end coil of the utility model is that a single metal wire is wound in a coaxial and equal-diameter axial extension manner, which is similar to a circle when viewed from the top and like a circle when viewed from the side. Figure 3The transmitting coil can be wound around the waste food disposer inlet pipe wall, and the inner wall of the transmitting coil can generate an induced magnetic field around the waste food disposer inlet pipe wall. The receiving coil can be wound in a conventional way or in the same way as the transmitting coil, the purpose of which is to increase the induction range, so that the use operation does not need to be aligned, and the use is more convenient.

[0060] like Figure 5-8 As shown, the switch control circuit includes: MCU chip U1, resistor R1, resistor R8, resistor R9, capacitor C1, voltage regulator diode ZD1, fuse F; the wireless induction transmission control circuit includes: resistor RS1, resistor R3, resistor R4, wireless induction transmission chip U2, capacitor C2, capacitor C3;

[0061] The input power supply is connected to one end of the fuse F; the other end of the fuse F is respectively connected to one end of the resistor R1 and one end of the resistor R8; the other end of the resistor R1 is respectively connected to one end of the capacitor C1, the cathode of the voltage-stabilizing diode ZD1, and the Vdd interface of the MCU chip U1; the other end of the resistor R8 is respectively connected to one end of the resistor R9 and an I / O interface PA5 of the MCU chip U1; the other end of the capacitor C1, the anode of the voltage-stabilizing diode ZD1, the other end of the resistor R9, and the VSS interface of the MCU chip U1 are grounded; an I / O interface PA7 of the MCU chip U1 is connected to the wireless induction transmitting chip U2 as an output end of the state control signal of the wireless induction transmitting chip The N / F interface of the transmitting chip U2 is connected; the R interface of the wireless induction transmitting chip U2 is connected to one end of the resistor R3; the Vin interface of the wireless induction transmitting chip U2 is respectively connected to one end of the capacitor C2 and one end of the transmitting coil 7; the VDD interface of the wireless induction transmitting chip U2 is respectively connected to the other end of the capacitor C2, the other end of the transmitting coil 7, one end of the capacitor C3, one end of the resistor R4, and the input power supply; the other end of the resistor R4 is connected to the other end of the resistor R3; the GND interface of the wireless induction transmitting chip U2 is respectively connected to an I / O interface PA5 of the MCU chip U1, one end of the resistor RS1, and the other end of the capacitor C3; the other end of the resistor RS1 is grounded.

[0062] When working, the PA5 interface of the MCU chip U1 will detect the voltage on the resistor R9 to determine whether the input voltage is undervoltage / overvoltage / normal working state. If it is undervoltage or overvoltage, the product will not work. Undervoltage or overvoltage is to detect whether there is a problem with the input power supply to prevent the input voltage from being too low or too high and causing the device to fail. If the voltage is within the range, the PA7 interface of the MCU chip U1 will send a pulse signal to the N / F interface of the wireless induction transmitter chip U2. After the internal switch of the wireless induction transmitter chip U2 works, the current will flow through the fuse F, the transmitting coil L1, the Vin interface of the wireless induction transmitter chip U2, the GND interface of the wireless induction transmitter chip U2, and the resistor RS1 in turn. At this time, a voltage will be generated on the resistor RS1, and the PAN2 interface of the MCU chip will use this voltage to determine the status of the product: standby / overcurrent / normal working; at the same time, the MCU chip will calculate the current size according to the resistance value of the resistor RS1 and the voltage obtained (equivalent to the voltage at both ends of the resistor RS1), and determine whether there is metal passing through the transmitting coil 7 and entering the inlet 8 of the waste food processor according to the change of the current.

[0063] The wireless induction receiving circuit includes: a diode D1, a capacitor C4, a capacitor C5, a resistor R5, and an LED indicator LED2;

[0064] The receiving coil 4, i.e., one end of the coil L2 is respectively connected to the anode of the diode D1 and one end of the capacitor C4; the cathode of the diode D1 is respectively connected to one end of the capacitor C5 and one end of the resistor R5, serving as the output end of the wireless induction receiving circuit; the other end of the resistor R5 is connected to one end of the LED indicator LED2; the other end of the coil L2, the other end of the capacitor C4, the other end of the capacitor C5, and the other end of the LED indicator LED2 are grounded; the LED indicator LED2 is used to indicate whether the receiving coil 4 has power.

[0065] The control circuit of the ultraviolet lamp 51 includes: an inductor L3, a resistor RS2, a resistor R6, a resistor R7, a capacitor C6, a capacitor C7, a capacitor C8, a diode D2, and an LED driver chip U3;

[0066] The output end of the wireless induction receiving circuit is respectively connected to one end of the ultraviolet lamp LED1, one end of the capacitor C7 and one end of the inductor L3; the other end of the ultraviolet lamp LED1 is respectively connected to one end of the resistor RS2 and the CS interface of the LED driver chip U3; the OVP interface of the LED driver chip U3 is respectively connected to one end of the resistor R6 and one end of the resistor R7; the COMP interface of the LED driver chip U3 is connected to one end of the capacitor C6; the VOUT interface of the LED driver chip U3 is respectively connected to the other end of the resistor RS2, the other end of the resistor R6, the other end of the capacitor C7, and the cathode of the diode D2; the VDD interface of the LED driver chip U3 is connected to one end of the capacitor C8; the SW interface of the LED driver chip U3 is connected to the other end of the inductor L3; the other end of the resistor R7, the other end of the capacitor C6, the other end of the capacitor C8, and the GND interface of the LED driver chip U3 are grounded.

[0067] In the above circuit, the ultraviolet lamp 51 is preferably a UV lamp, the model of the wireless sensing transmitter chip U2 is: XKT-518; the model of the LED driver chip U3 is: BP1808.

[0068] During use, after the waste food processor has crushed and rinsed the food, the shell of the utility model is inserted into the inlet 8 of the waste food processor until it reaches the limit position. At this time, the current of the transmitting coil 7 of the base that is engaged at the same height of the outer wall of the inlet 8 of the waste food processor will change, and the utility model device is allowed to work. When the utility model device is working, the ultraviolet lamp 51 irradiates into the crushing chamber, which can sterilize the crushing chamber with ultraviolet rays and eliminate the odor in the crushing chamber. After use, the shell can be pulled out. At this time, the coil between the shell and the base loses the wireless induction effect, the receiving coil 4 of the shell loses the power supply capacity, and the ultraviolet lamp 51 stops working to prevent the ultraviolet lamp 51 from causing damage to the human body. In addition, the current of the transmitting coil 7 on the base will change, entering a low power consumption mode to save electricity.

[0069] When not in use, the product is in low power consumption mode. If a metal foreign object accidentally enters the food waste processor inlet 8, the current of the transmitting coil 7 on the base will change, and the product will enter abnormal protection mode to improve safety.

[0070] It should be noted that the waste food processor is an existing device, and its inlet is installed at the drain of the kitchen sink, and the waste food can enter the crushing chamber through the inlet. Existing equipment can be used for ion generators and ozone generators. The utility model does not limit the specific internal structure and function implementation method of the sterilization equipment. As long as the sterilization equipment can achieve the sterilization function, it can be used. The utility model changes the winding method of the transmitting coil 7 and the receiving coil 4, but does not change the principle of wireless induction, and will not affect the understanding and implementation of the wireless induction power supply process by those skilled in the art. It should also be noted that the connection method, installation method, etc. described in the utility model, if it is not clearly stated how to implement, are all conventional technical means in the field, and there is no possibility of being unable to implement; the circuit diagram provided by the utility model is a schematic diagram, and those skilled in the art can improve the circuit on this basis in combination with conventional technical means in the field. At the same time, those skilled in the art can also understand and directly implement it according to the circuit schematic diagram and function description provided, and there is no possibility of being unable to implement.

[0071] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
