[0016] The control terminal of the distance detection module is connected to the output terminal of the object recognition module, and the output terminal of the distance detection module is connected to the user equipment.
[0017] The item recognition module is also used to output an item storage signal to the distance detection module when it is detected that there are items stored in the refrigerator;
[0018] The distance detection module is used to detect the communication distance between the item recognition module and the user device after receiving the item storage signal, and to output a trigger signal to the user device when the communication distance is greater than a preset distance threshold, so as to trigger the user device to remind the user device of missing items.
[0019] In one embodiment, the distance detection module includes a distance sensor and a comparator;
[0020] The distance sensor is mounted on the object recognition module. The control terminal of the distance sensor is connected to the output terminal of the object recognition module. The output terminal of the distance sensor is connected to the positive input terminal of the comparator. The negative input terminal of the comparator is connected to the preset distance threshold. The output terminal of the comparator is connected to the user equipment.
[0021] The distance sensor is used to detect the communication distance between the item recognition module and the user equipment after receiving the item storage signal;
[0022] The comparator is used to compare the communication distance with the preset distance threshold, and when the communication distance is greater than the preset distance threshold, it outputs a trigger signal to the user equipment to trigger the user equipment to provide an item loss reminder.
[0023] In one embodiment, the refrigerator item identification device further includes a switch detection module;
[0024] The switch detection module is installed on the refrigerator door. The output of the switch detection module is connected to the item recognition module. It is used to detect the open / closed state of the refrigerator door.

[0025] In addition, to achieve the above objectives, this utility model also provides a vehicle refrigerator, which includes a refrigerator body and a refrigerator item identification device as described above, wherein the refrigerator item identification device is disposed on the refrigerator body.
[0026] In addition, to achieve the above objectives, this utility model also provides a vehicle, which includes a vehicle body, a vehicle-mounted refrigerator, and a refrigerator item identification device as described above. The vehicle-mounted refrigerator is located on the vehicle body, and the refrigerator item identification device is located on the refrigerator body of the vehicle-mounted refrigerator.
[0027] This utility model provides a refrigerator item identification device, which includes: an item long-term storage reminder module, an item identification module, and a timing module; the item identification module is disposed inside the refrigerator body, the input end of the timing module is connected to the output end of the item identification module, and the output end of the timing module is connected to the input end of the item long-term storage reminder module; the item identification module is used to identify items stored in the refrigerator; the timing module is used to record the duration for which the item identification module identifies the same item, and when the duration reaches a preset time threshold, it outputs a trigger signal to the item long-term storage reminder module to trigger the item long-term storage reminder module to provide an item long-term storage reminder.
[0028] Therefore, this invention incorporates an item recognition module within the refrigerator body to identify items stored inside. A timing module is placed between the item recognition module and the long-term storage reminder module to record the duration for which the item recognition module identifies the same item. Thus, when the duration for which the item recognition module identifies the same item reaches a preset time threshold—that is, when the item has been in the refrigerator for an extended period—the long-term storage reminder module is triggered to remind the user of the presence of items stored for an extended period in the refrigerator. This invention effectively triggers a reminder mechanism when items stored for an extended period are present in the vehicle refrigerator, ensuring that the user does not miss the items inside and effectively preventing items from remaining in the refrigerator for extended periods due to forgetfulness.

[0041] With the improvement of people's living standards, the use of car refrigerators is becoming increasingly common. Car refrigerators are mainly divided into two types: semiconductor car refrigerators and compressor car refrigerators. Although their refrigeration principles differ, they both basically include a power supply system, refrigeration unit, refrigeration (freezing) space, insulation components, heat dissipation system, and control system. The refrigeration (freezing) space of a refrigerator is usually a cabinet with internal storage space for placing items; the size of this storage space varies depending on the refrigerator model.
[0042] Currently, users often forget that they have items stored in their car refrigerators, leading to items being stored for too long, causing damage or spoilage, and resulting in losses and inconvenience for the users.
[0043] Based on this, the present invention provides a refrigerator item identification device. In the first embodiment of the present invention, please refer to... Figure 1 The refrigerator item recognition device may include an item long-term storage reminder module 10, an item recognition module 20, and a timing module 30; the item recognition module 20 is located inside the refrigerator body, the input end of the timing module 30 is connected to the output end of the item recognition module 20, and the output end of the timing module 30 is connected to the input end of the item long-term storage reminder module 10.
[0044] Item recognition module 20 is used to identify items stored in the refrigerator;
[0045] The timing module 30 is used to record the duration of the same item being identified by the item recognition module 20, and when the duration reaches a preset time threshold, it outputs a trigger signal to the item long-term storage reminder module 10 to trigger the item long-term storage reminder module 10 to provide an item long-term storage reminder.
[0046] It should be noted that the preset time threshold is used as a basis for determining whether the item has been placed in the refrigerator for a long time. It can be a default value, such as 1 day (i.e., 24 hours); or it can be flexibly set by the user according to the actual situation. This embodiment does not make specific limitations on this.
[0047] Additionally, it should be noted that the item long-term storage reminder module 10 can be a buzzer, indicator light, display, voice reminder module, vibration reminder device, or other device with reminder function, etc., and this embodiment does not specifically limit it. The timing module 30 can be a timer, time relay, or other device or circuit with timing function, etc., and this embodiment does not specifically limit it. In actual use, both the item long-term storage reminder module 10 and the timing module 30 can be installed in the control system of the vehicle refrigerator.
[0048] In one feasible implementation, the item identification module 20 may include a reader / writer and at least one item identification card;
[0049] Both the item identification card and the reader are located inside the refrigerator body. The reader is connected to the item identification card, and the output of the reader is connected to the input of the timing module 30.
[0050] The item identification card is used to connect to items stored in the refrigerator;
[0051] The reader is used to scan item identification cards to identify items stored in the refrigerator.
[0052] It should be noted that the item identification card can have multiple card slots, each of which can contain an item tag. The item tag corresponds to the type or information of the item connected to the item identification card (e.g., item name, shelf life, optimal storage temperature, or user-defined item attributes). The item identification card can be fixed in a fixed manner (e.g., using a clip) to connect to the items stored in the refrigerator. The item identification card can be an NFC (Near Field Communication) card, Bluetooth card, barcode card, QR code card, etc., and this embodiment does not specifically limit this. The reader / writer can be an NFC reader / writer, Bluetooth reader / writer, barcode reader / writer, QR code reader / writer, etc., and this embodiment does not specifically limit this. By scanning the item identification card, the reader / writer can read the relevant information about the connected item from the item identification card, thereby identifying the items stored in the refrigerator.
[0053] Among them, when using NFC identification cards and NFC readers to identify items in the refrigerator, not only is the identification accuracy high, but the cost and complexity of identification are also low.
[0054] In another feasible implementation, the item recognition module 20 can be a camera device.
[0055] It should be noted that the camera device can be a camera, webcam, image sensor, or other device with image capture and recognition functions, and this embodiment does not specifically limit it.
[0056] Understandably, by taking pictures of the inside of a refrigerator with a camera, the items stored inside can be identified using those pictures.
[0057] The above are just two feasible structural compositions of the item recognition module 20 provided in this embodiment. This embodiment does not specifically limit the specific structural composition of the item recognition module 20.
[0058] This embodiment provides a refrigerator item identification device, which includes: an item long-term storage reminder module 10, an item identification module 20, and a timing module 30. The item identification module 20 is disposed inside the refrigerator body. The input terminal of the timing module 30 is connected to the output terminal of the item identification module 20, and the output terminal of the timing module 30 is connected to the input terminal of the item long-term storage reminder module 10. The item identification module 20 is used to identify items stored in the refrigerator. The timing module 30 is used to record the duration for which the item identification module 20 identifies the same item, and when the duration reaches a preset time threshold, it outputs a trigger signal to the item long-term storage reminder module 10 to trigger the item long-term storage reminder module 10 to provide an item long-term storage reminder.
[0059] Therefore, this embodiment uses an item recognition module 20 within the refrigerator body to identify items stored inside. A timing module 30 is placed between the item recognition module 20 and the item long-term storage reminder module 10 to record the duration for which the item recognition module 20 identifies the same item. Thus, when the duration for which the item recognition module 20 identifies the same item reaches a preset time threshold—that is, when the item has been in the refrigerator for a relatively long time—the item long-term storage reminder module 10 will be triggered to provide a timely reminder to the user that an item has been stored in the refrigerator for an extended period. Therefore, this embodiment can promptly trigger a reminder mechanism when there are items stored for a long time in the vehicle refrigerator, ensuring that the user does not miss the items in the refrigerator and effectively avoiding the problem of items remaining in the refrigerator for extended periods due to forgetfulness.
[0060] In addition, in other embodiments, the timing module in this embodiment can be replaced with a counting module to record the number of times the item recognition module 20 continuously recognizes the same item, and when the number of consecutive recognitions reaches a preset threshold, the counting module outputs a trigger signal to the item long-term storage reminder module to trigger the item long-term storage reminder module to provide an item long-term storage reminder.
[0061] The preset threshold number of times is used to determine whether an item has been placed in the refrigerator for a relatively long time. It can be a default value, such as 100 times; however, it can also be flexibly set by the user according to actual circumstances. This embodiment does not impose specific limitations on this. The counting module can be a counter or other devices or circuits with counting functions. This embodiment does not impose specific limitations on this either.
[0062] Based on the first embodiment described above, a second embodiment of the refrigerator item identification device of this utility model is proposed. For the second embodiment, please refer to... Figure 2 The item recognition module 20 can also communicate with the user equipment, and the refrigerator item recognition device can also include a distance detection module 40 set on the item recognition module 20;
[0063] The control terminal of the distance detection module 40 is connected to the output terminal of the item recognition module 20, and the output terminal of the distance detection module 40 is connected to the user equipment.
[0064] The item recognition module 20 is also used to output an item storage signal to the distance detection module 40 when it is recognized that there are items stored in the refrigerator;
[0065] The distance detection module 40 is used to detect the communication distance between the item recognition module 20 and the user device after receiving the item storage signal, and to output a trigger signal to the user device when the communication distance is greater than a preset distance threshold, so as to trigger the user device to remind the user device of the item being left behind.
[0066] It should be noted that the user equipment can be a mobile electronic device carried by the user, such as a mobile phone, tablet, or smartwatch; this embodiment does not specifically limit this. The item storage signal is used to indicate that items are stored in the refrigerator. When the item recognition module 20 detects that items are stored in the refrigerator, it can output a high-level signal, which is the item storage signal. The preset distance threshold is used to determine whether the user has left the vehicle. It can be a default value or can be flexibly set by the user according to the actual situation; this embodiment does not specifically limit this.
[0067] In one feasible implementation, please refer to Figure 3 The distance detection module 40 may include a distance sensor L1 and a comparator U1;
[0068] The distance sensor L1 is installed on the object recognition module 20. The control terminal of the distance sensor L1 is connected to the output terminal of the object recognition module 20. The output terminal of the distance sensor L1 is connected to the positive input terminal of the comparator U1. The negative input terminal of the comparator U1 is connected to the preset distance threshold Vlset. The output terminal of the comparator U1 is connected to the user equipment.
[0069] Distance sensor L1 is used to detect the communication distance between the item identification module 20 and the user equipment after receiving the item storage signal;
[0070] Comparator U1 is used to compare the communication distance with the preset distance threshold Vlset. If the communication distance is greater than the preset distance threshold Vlset, it outputs a trigger signal to the user device to trigger the user device to remind it of missing items.
[0071] It should be noted that when the communication distance is greater than the preset distance threshold Vlset, comparator U1 will output a high-level signal, which is the trigger signal output by comparator U1 to the user equipment.
[0072] In this embodiment, the item recognition module 20 is communicatively connected to the user device, and a distance detection module 40 is installed on the item recognition module 20. Upon receiving an item storage signal, the communication distance between the item recognition module 20 and the user device is detected. Therefore, if the communication distance exceeds a preset distance threshold Vlset, i.e., if the user leaves the vehicle but the car refrigerator still contains items, the user device will be triggered to issue an item forgetting reminder. Thus, this embodiment can promptly issue item forgetting reminders when the user leaves the vehicle but items remain in the car refrigerator, effectively preventing items from being left in the refrigerator.
[0073] Based on the first and / or second embodiments described above, a third embodiment of the refrigerator item identification device of this utility model is proposed. In the third embodiment, please refer to... Figure 4 The refrigerator item recognition device may also include a switch detection module 50;
[0074] The switch detection module 50 is installed on the refrigerator door. The output of the switch detection module 50 is connected to the item recognition module 20 to detect the switch status of the refrigerator door. When the switch door is detected to be open, the module outputs a trigger signal to the item recognition module 20 to trigger the item recognition module 20 to recognize the items in the refrigerator.
[0075] It should be noted that the opening and closing state of the door can include both the open and closed states. The switch detection module 50 can be a switch sensor, Hall sensor, proximity sensor, barometric pressure sensor, image recognition device, or other device or circuit with the function of detecting the opening and closing state of the door, etc., and this embodiment does not specifically limit it.
[0076] Understandably, considering that items can only be put in and taken out after the refrigerator door is opened, this embodiment installs a switch detection module 50 on the refrigerator door to detect the open / closed state of the refrigerator door, so that when the switch detection module 50 detects that the door is open, it can trigger the item recognition module 20 to identify the items in the refrigerator.
[0077] For example, the refrigerator item recognition device obtained by combining the above embodiments can be referred to Figure 5 The form shown is provided on the refrigerator body of the vehicle refrigerator ( Figure 5 The main focus is on the placement of the various modules in the refrigerator's item recognition device on the refrigerator body, so only the connections between some modules are shown. The timing module 30 and the long-term storage reminder module 10 can be installed on the exterior of the vehicle refrigerator or inside the refrigerator.
[0078] It should be noted that this example is only for the purpose of assisting in understanding the present invention and does not constitute a limitation on the refrigerator item identification device of the present invention. Any simple modifications based on this technical concept are within the protection scope of the present invention.
[0079] This utility model also provides a vehicle-mounted refrigerator, which includes a refrigerator body and the aforementioned refrigerator item identification device, wherein the refrigerator item identification device is disposed on the refrigerator body.
