Detailed Implementation

[0045] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0046] In daily life, users usually hang cutting boards to dry after use, but the residual moisture and food residue often cause bacterial growth, making the cutting board unhygienic. To avoid the hygiene of cutting boards affecting people's dietary health, the commonly used method for disinfecting cutting boards is to spray them with disinfectant using a cutting board disinfection machine.

[0047] However, if the cutting board sterilizer tilts over when the above disinfection method is used, the disinfectant solution inside will spill out from the top utensil placement opening, resulting in a low safety factor.

[0048] Based on the aforementioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a tilt detection component 1, a sealing door 2, a drive motor 3, and a control board 4. The tilt detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil containing cavity 502 of the cutting board sterilizer. The output shaft of the drive motor 3 is coaxially fixed with the rotation shaft of the sealing door 2. The control board 4 is electrically connected to the tilt detection component 1 and the drive motor 3, respectively, to control the drive motor 3 to adjust the opening and closing state of the kitchen utensil containing cavity 502 based on the tilt voltage signal detected by the tilt detection component 1. Therefore, in the event of a tilting of the cutting board sterilizer, the opening of the kitchen utensil containing cavity 502, which allows the internal disinfectant to be discharged, can be closed. This prevents the disinfectant from spilling and improves the safety factor of the cutting board sterilizer.

[0049] Reference Figure 1-6This utility model provides an anti-tipping device, which may include a tipping detection component 1, a sealing door 2, a drive motor 3, and a control board 4. The tipping detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil cavity 502 of the cutting board sterilizer. The output shaft of the drive motor 3 is coaxially fixed with the rotation shaft of the sealing door 2. The control board 4 is electrically connected to the tipping detection component 1 and the drive motor 3, respectively, so as to control the drive motor 3 to adjust the opening and closing state of the opening of the kitchen utensil cavity 502 by using the tipping voltage signal detected by the tipping detection component 1.

[0050] In this embodiment of the utility model, the anti-tipping device may include a tipping detection component 1, a sealing door 2, a drive motor 3, and a control board 4.

[0051] The tipping detection component 1 refers to a collection of related parts used to detect whether the cutting board sterilizer has tipped over. The tipping detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. For example, the tipping detection component 1 can be embedded in the outer shell assembly 5.

[0052] The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil cavity 502 of the cutting board sterilizer. A cutting board sterilizer typically includes multiple cavities, such as a cutting board cavity 501 and a kitchen utensil cavity 502. The cutting board cavity 501 is used to hold cutting boards, which are typically placed into it through a side opening of the sterilizer. It is usually closed during sterilization operation. The kitchen utensil cavity 502 is used to hold kitchen utensils such as knives, chopsticks, and spoons.

[0053] Normally, kitchen utensils are placed into the utensil cavity 502 through the top opening. It is usually not closed when operating in disinfection mode. Therefore, by adding the sealing door 2 to the opening of the utensil cavity 502, the cavity can be sealed promptly in the event of the cutting board sterilizer tipping over, preventing disinfectant or hot air from spilling out and posing a safety threat to the user.

[0054] The drive motor 3 is a power source component, and its output shaft is coaxially fixed with the rotation axis of the closed door 2. That is, the central axis of the output shaft of the drive motor 3 coincides with the central axis of the rotation axis of the closed door 2, and the output shaft of the drive motor 3 is fixedly connected to the rotation axis of the closed door 2. Thus, the drive motor 3 can be installed on the housing assembly 5 and used to drive the closed door 2 to rotate, closing or opening the opening of the kitchen utensil accommodating cavity 502.

[0055] The control board 4 is electrically connected to the tilt detection component 1 and the drive motor 3, respectively. Therefore, the control board 4 can control the operating state of the drive motor 3. The tilt detection component 1 can transmit the detected tilt voltage signal to the control board 4. The control board 4 then controls the drive motor 3 to adjust the opening and closing state of the kitchen utensil cavity 502. Thus, in the event of a tipping over, the opening of the kitchen utensil cavity 502, which allows the internal disinfectant to drain, can be closed. This prevents disinfectant spillage or hot air leakage, improving the safety of the cutting board sterilizer.

[0056] In one optional embodiment of the utility model, referring to Figure 2 and Figure 3 As shown, the tipping detection assembly 1 may include a detection housing 11, a detection base 12, a shielding member 13, and a light detection circuit 14. The detection housing 11 is disposed on the outer shell assembly 5, and the detection base 12 is located on the detection housing 11 and has a displacement groove 1201. The shielding member 13 is embedded in the displacement groove 1201. The light detection circuit 14 is coupled to the control board 4 and includes at least a light detection mechanism 141, which is disposed on the detection housing 11. The shielding member 13 is located in the light detection mechanism 141 and is used to adjust the light intensity output by the light detection mechanism 141 by displacement when the posture of the cutting board sterilizer is switched.

[0057] In this embodiment of the invention, the detection housing 11 provides structural support and mounting for other components of the tilt detection assembly 1. Its material can be consistent with that of the outer shell assembly 5. For example, the detection housing 11 can be embedded within the outer shell assembly 5. Alternatively, the detection housing 11 and the outer shell assembly 5 can be detachably connected by fasteners such as screws. Or, the detection housing 11 and the outer shell assembly 5 can be fixed by snap-fit.

[0058] The detection base 12 is disposed on the detection housing 11. For example, the detection base 12 can be fixed to the inner bottom of the detection housing 11. A displacement groove 1201 is formed on the surface of the detection base 12. The displacement groove 1201 is used to define the movement trajectory of the blocking member 13, and the blocking member 13 is embedded in the displacement groove 1201. In one example, the blocking member 13 can be a spherical structure, thereby facilitating its rolling within the displacement groove 1201. The rolling arrangement of the blocking member 13 along the displacement groove 1201 improves the sensitivity of its movement when the cutting board sterilizer undergoes a change in posture, thereby increasing the position detection response speed of the cutting board sterilizer.

[0059] The blocking member 13 is located in the light detection structure of the light detection circuit 14. The light detection structure can be understood as a collection of detection devices that determine the current position of the blocking member 13 by detecting light intensity. The current position of the blocking member 13, corresponding to the voltage signal of the light intensity change caused by its blocking, can be used to determine whether the cutting board sterilizer has tipped over. For example, when the cutting board sterilizer changes from a horizontal position to an inclined position, its posture changes. At this time, the blocking member 13 moves synchronously along the displacement groove 1201 along with the posture change of the cutting board sterilizer. Therefore, the position of the blocking member can cause a difference in the light intensity of the light detection mechanism 141, resulting in different levels at the detection output terminal 1441 of the light detection circuit 14.

[0060] In one optional embodiment of the utility model, referring to Figure 2 and Figure 3 As shown, the light detection mechanism 141 includes a light emitter 1411 and a light receiver 1412. The light emitter 1411 and the light receiver 1412 are spaced apart on the detection housing 11 and are arranged facing each other to form a through-beam optical path. For example, the light emitter 1411 and the light receiver 1412 can be respectively embedded in the side of the detection housing 11. Alternatively, the light emitter 1411 and the light receiver 1412 can be indirectly fixed to the detection housing 11 using a connector; no further limitations are specified here. The light emitter 1411 can be used to emit a light source, and the light receiver 1412 can change its resistance based on the intensity of the received light. For example, the stronger the light intensity received by the light receiver 1412, the smaller its corresponding resistance. Therefore, the light intensity received by the light receiver 1412 can be determined based on the light intensity voltage signal output from the detection output terminal 1441 of the light detection circuit 14 where the light receiver 1412 is located.

[0061] In one or more embodiments, the light emitting element 1411 includes an infrared emitting diode, and the light receiving element 1412 includes an infrared receiving diode. The infrared emitting diode can emit infrared light, and the stronger the intensity of the infrared light received by the infrared receiving diode, the lower its own resistance value. The light receiving element 1412 may include photoresistors, photodiodes, and phototransistors, etc., and is not limited thereto.

[0062] In another or more embodiments, the light emitting element 1411 includes a visible light emitting tube, and the light receiving element 1412 includes a visible light receiving tube. The visible light emitting tube is a device that generates visible light by exciting a semiconductor material with an electric current. The visible light receiving tube can generate an electrical signal by absorbing visible light energy. The stronger the intensity of the visible light received by the visible light receiving tube, the lower its own resistance value.

[0063] In another embodiment or more, the light emitting element 1411 includes a laser emitting tube, and the light receiving element 1412 includes a laser receiving tube. The laser emitting tube emits light through stimulated emission, and the laser receiving tube can generate an electrical signal by absorbing laser energy. The stronger the light intensity of the laser light received by the laser receiving tube, the lower its own resistance value.

[0064] In summary, those skilled in the art can select the light source type of the light emitting element 1411 and the light receiving element 1412 according to actual design requirements and product costs, without making any further limitations here.

[0065] The blocking member 13 is distributed in the area between the light emitter 1411 and the light receiver 1412, and is used to switch the blocking state of the through-beam light path by moving along the displacement groove 1201 when the posture of the cutting board sterilizer changes. That is, the blocking state includes two states: blocked and unblocked. When the posture of the cutting board sterilizer changes, for example, from a horizontal setting to a tilted setting, the blocking member 13 can move along the displacement groove 1201 with the posture change of the cutting board sterilizer, and switch the blocking state of the through-beam light path under different postures. Thus, according to the significant difference in the resistance value of the light receiver 1412 under different blocking states, the detection output terminal 1441 of the light detection circuit 14 outputs different levels. And the different levels are used to determine whether the cutting board sterilizer has tipped over. If it is determined that it has tipped over, the control board 4 controls the drive motor 3 to rotate, so that the sealing door 2 can close the opening of the kitchenware accommodating cavity 502.

[0066] In one optional embodiment of the utility model, when the cutting board sterilizer is set horizontally, the blocking member 13 moves along the displacement groove 1201 into the through-beam light path, blocking the through-beam light path. That is, the light intensity of the light receiver 1412 is weak or approximately zero. At this time, the resistance value of the light receiver 1412 is very large, forming an open circuit in the light detection circuit 14. The detection output terminal 1441 of the light detection circuit 14 can output a high level or a low level.

[0067] When the cutting board sterilizer tilts, the blocking member 13 moves along the displacement groove 1201 to outside the through-beam light path. At this time, the through-beam light path is not blocked, and the light receiver 1412 receives all the light from the light emitter 1411, resulting in a strong light intensity. The resistance of the light receiver 1412 is very small, causing it to conduct in the light detection circuit 14. Therefore, the detection output terminal 1441 of the light detection circuit 14 can output a low or high level. Thus, the significant difference between the high and low levels under different blocking states can determine whether the posture of the cutting board sterilizer has changed.

[0068] In another optional embodiment of the utility model, when the cutting board sterilizer is set horizontally, the blocking member 13 moves along the displacement groove 1201 to outside the through-beam light path. At this time, the through-beam light path is not blocked, and the light receiver 1412 receives all the light source from the light emitter 1411, resulting in a strong light intensity. The resistance value of the light receiver 1412 is very small, forming a conductive circuit in the light detection circuit 14. The detection output terminal 1441 of the light detection circuit 14 is at a high or low level.

[0069] When the cutting board sterilizer tilts, the blocking member 13 moves along the displacement groove 1201 into the through-beam light path, blocking it. That is, the light intensity of the light receiver 1412 is weak or approximately zero, and its resistance is very high, creating an open circuit in the light detection circuit 14. The detection output terminal 1441 of the light detection circuit 14 then enters a low or high level.

[0070] In one optional embodiment of the utility model, referring to Figure 4 , Figure 5 as well as Figure 6As shown, the optical detection circuit 14 may further include a first current-limiting resistor 142, a second current-limiting resistor 143, and an output resistor 144. The first current-limiting resistor 142 is coupled to the positive terminal of the optical emitter 1411. The second current-limiting resistor 143 is coupled to the positive terminal of the optical receiver 1412. The negative terminals of the optical emitter 1411 and the optical receiver 1412 are respectively grounded. The end of the first current-limiting resistor 142 away from the optical emitter 1411 and the end of the second current-limiting resistor 143 away from the optical emitter 1411 are respectively coupled to the power supply. The output resistor 144 is coupled between the second current-limiting resistor 143 and the positive terminal of the optical receiver 1412. The resistance value of the output resistor 144 is greater than the resistance value of the second current-limiting resistor 143. The end of the output resistor 144 away from the second current-limiting resistor 143 serves as the detection output terminal 1441 of the optical detection circuit 14. The detection output terminal 1441 is coupled to the control board 4.

[0071] In this embodiment of the invention, the optical detection circuit 14 may further include a first current-limiting resistor 142, a second current-limiting resistor 143, and an output resistor 144. The first current-limiting resistor 142 is connected in series with the optical emitter 1411 and is used to limit the operating current of the optical emitter 1411 to prevent overcurrent damage. The positive terminal of the optical emitter 1411 is coupled to the first current-limiting resistor 142 and then to a power supply, which supplies power to the optical emitter 1411. The negative terminal of the optical emitter 1411 is grounded. The optical emitter 1411 can continuously emit detection light when powered on.

[0072] The second current-limiting resistor 143 is connected in series with the optical receiver 1412. The second current-limiting resistor 143 limits the operating current of the optical receiver 1412 to prevent overcurrent damage. The positive terminal of the optical receiver 1412 is coupled to the second current-limiting resistor 143 and then to a power supply, which supplies power to the optical receiver 1412. The negative terminal of the optical receiver 1412 is grounded. The optical receiver 1412 can change its resistance value (or equivalent resistance value) according to the intensity of the received detection light. One end of the output resistor 144 is coupled between the second current-limiting resistor 143 and the positive terminal of the optical receiver 1412. The other end of the output resistor 144 serves as the detection output terminal 1441 of the optical detection circuit 14. The current change of the second resistor can be converted into a voltage change through the output resistor 144, and input to the control board 4 coupled to the detection output terminal 1441.

[0073] In one example, when the through-beam optical path is blocked by the blocking member 13, the resistance of the light receiver 1412 is relatively large, and it can be considered an open circuit. The second current-limiting resistor 143 and the output resistor 144 are connected in series to divide the voltage. When the resistance of the output resistor 144 is much larger than the resistance of the second current-limiting resistor 143, the voltage value output by the detection output terminal 1441 is equal to or close to the voltage value of the power supply, thus outputting a high level. When the through-beam optical path is not blocked by the blocking member 13, the resistance of the light receiver 1412 is relatively small, forming a conductive circuit. The second current-limiting resistor 143 is grounded through the light receiver 1412, making the output resistor 144 approximately without current. Therefore, the voltage value output by the detection output terminal 1441 can be considered approximately or equal to the ground voltage, thus outputting a low level. When the control board 4 receives a low level or a high level input from the detection output terminal 1441, it determines that the cutting board sterilizer has tipped over and controls the drive motor 3 to operate so that the sealing door 2 opens and closes.

[0074] In one optional embodiment of the utility model, the displacement groove 1201 is formed inside the detection base 12 and is a conical groove. When the cutting board sterilizer is horizontally positioned, the blocking member 13 is located at the apex of the cone of the displacement groove 1201, which can be understood as the lowest point of the displacement groove 1201, thus blocking the through-beam light path. When the cutting board sterilizer tilts, the blocking member 13 slides along the displacement groove 1201 away from the through-beam light path. That is, during the tilting process of the cutting board sterilizer, the apex of the cone of the displacement groove 1201 is no longer the lowest point, causing the blocking member 13 to roll along the side of the displacement groove 1201 away from the through-beam light path. When the cutting board sterilizer returns to a horizontal position, the apex of the cone of the displacement groove 1201 becomes the lowest point again, allowing the blocking member 13 to roll down again under the action of gravity, restoring its state of blocking the through-beam light path. In the blocking state, the drive motor 3 can drive the opening of the closed door.

[0075] In summary, this utility model discloses an anti-tipping device, which may include a tilt detection component 1, a sealing door 2, a drive motor 3, and a control board 4. The tilt detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil cavity 502 of the cutting board sterilizer. The output shaft of the drive motor 3 is coaxially fixed with the rotation shaft of the sealing door 2. The control board 4 is electrically connected to the tilt detection component 1 and the drive motor 3, respectively, so as to control the drive motor 3 to adjust the opening and closing state of the kitchen utensil cavity 502 by means of the tilt voltage signal detected by the tilt detection component 1. Thus, in the event of a tipping of the cutting board sterilizer, the opening of the kitchen utensil cavity 502, which allows the internal disinfectant to be discharged, can be closed. This prevents the disinfectant from spilling out and improves the safety factor of the cutting board sterilizer.

[0076] Reference Figure 1 and Figure 7 As shown, this utility model embodiment also provides a cutting board sterilizer, which may include an anti-tipping device and a housing assembly 5 as described in any of the above utility model embodiments. The housing assembly 5 encloses a cutting board receiving cavity 501 and a kitchen utensil receiving cavity 502 communicating with the cutting board receiving cavity 501. The cutting board receiving cavity 501 is used to receive cutting boards, which are usually placed into the cutting board receiving cavity 501 through a side opening of the cutting board sterilizer, and are usually in a closed state when operating the sterilization mode. The kitchen utensil receiving cavity 502 is used to receive kitchen utensils such as knives, chopsticks, and spoons. The opening of the kitchen utensil receiving cavity 502 faces the top of the housing assembly 5, and the kitchen utensil receiving cavity 502 is usually not closed when operating the sterilization mode.

[0077] The anti-tipping device may include a tipping detection component 1, a sealing door 2, a drive motor 3, and a control board 4. The tipping detection component 1 refers to a collection of components used to detect whether the cutting board sterilizer has tipped over. The tipping detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. For example, the tipping detection component 1 may be embedded within the outer shell assembly 5.

[0078] The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil cavity 502 of the cutting board sterilizer. A cutting board sterilizer typically includes multiple cavities, such as a cutting board cavity 501 and a kitchen utensil cavity 502. The cutting board cavity 501 is used to hold cutting boards, which are typically placed into it through a side opening of the sterilizer. It is usually closed during sterilization operation. The kitchen utensil cavity 502 is used to hold kitchen utensils such as knives, chopsticks, and spoons.

[0079] Normally, kitchen utensils are placed into the utensil cavity 502 through the top opening. It is usually not closed when operating in disinfection mode. Therefore, by adding the sealing door 2 to the opening of the utensil cavity 502, the cavity can be sealed promptly in the event of the cutting board sterilizer tipping over, preventing disinfectant or hot air from spilling out and posing a safety threat to the user.

[0080] The drive motor 3 is a power source component, and its output shaft is coaxially fixed with the rotation axis of the closed door 2. That is, the central axis of the output shaft of the drive motor 3 coincides with the central axis of the rotation axis of the closed door 2, and the output shaft of the drive motor 3 is fixedly connected to the rotation axis of the closed door 2. Thus, the drive motor 3 can be installed on the housing assembly 5 and used to drive the closed door 2 to rotate, closing or opening the opening of the kitchen utensil accommodating cavity 502.

[0081] The control board 4 is electrically connected to the tilt detection component 1 and the drive motor 3, respectively. Therefore, the control board 4 can control the operating state of the drive motor 3. The tilt detection component 1 can transmit the detected tilt voltage signal to the control board 4. The control board 4 then controls the drive motor 3 to adjust the opening and closing state of the kitchen utensil cavity 502. Thus, in the event of a tipping over, the kitchen utensil cavity 502 can be sealed promptly, preventing the disinfectant solution or hot air from spilling out of the cavity, thus avoiding any threat to user safety. This improves the safety and user experience of the cutting board sterilizer.

[0082] In one optional embodiment of the utility model, referring to Figure 1 and Figure 7 As shown, the cutting board sterilizer may include a main control board 6, which is electrically connected to the electrical components in the cutting board sterilizer, thereby controlling the operating status of the cutting board sterilizer. The control board 4 can be electrically connected to the main control board 6. Alternatively, the control board 4 of the anti-tipping device can be directly integrated into the main control board 6, thereby reducing the hardware cost of the cutting board sterilizer.

[0083] In summary, this utility model discloses an anti-tipping device and a cutting board sterilizer. This utility model embodiment may include a tilt detection component 1, a sealing door 2, a drive motor 3, and a control board 4. The tilt detection component 1 is located on the outer shell assembly 5 of the cutting board sterilizer. The sealing door 2 is rotatably connected to the outer shell assembly 5 at the opening of the kitchen utensil containing cavity 502 of the cutting board sterilizer. The output shaft of the drive motor 3 is coaxially fixed with the rotation shaft of the sealing door 2. The control board 4 is electrically connected to the tilt detection component 1 and the drive motor 3, respectively, to control the drive motor 3 to adjust the opening and closing state of the kitchen utensil containing cavity 502 based on the tilt voltage signal detected by the tilt detection component 1. Therefore, in the event of a tilting incident, the opening of the kitchen utensil containing cavity 502, which allows the internal disinfectant to be discharged, can be closed. This prevents the disinfectant from spilling and improves the safety of the cutting board sterilizer.
