[0006] A timing module, the input of which is connected to the output of the weight detection module and the output of which is connected to the input of the item storage reminder module, is used to record the duration for which the weight detection module detects the same refrigerator weight, and when the duration reaches a preset time threshold, outputs an electrical signal to the item storage reminder module to transmit the refrigerator weight detected by the weight detection module to the item storage reminder module through the electrical signal;
[0007] The item storage reminder module is used to receive the electrical signal and, when the weight of the refrigerator carried by the electrical signal is greater than a preset weight threshold, to remind the user to store items.

[0009] The positive input terminal of the comparator is connected to the output terminal of the timing module, the negative input terminal of the comparator is connected to the preset weight threshold, and the output terminal of the comparator is connected to the reminder unit;
[0010] The comparator is used to: receive the electrical signal, compare the weight of the refrigerator carried by the electrical signal with the preset weight threshold, and when the weight of the refrigerator carried by the electrical signal is greater than the preset weight threshold, output a trigger signal to the reminder unit to trigger the reminder unit to remind the user to store items.
[0011] In one embodiment, the weight detection module is a gravity sensor.
[0012] In one embodiment, the timing module is a timer.
[0013] In one embodiment, the refrigerator item detection device further includes a switch detection module;
[0014] The switch detection module is installed on the refrigerator door. The output of the switch detection module is connected to the weight detection module to detect the open / closed state of the refrigerator door. When the door is detected to be open, the switch detection module outputs a trigger signal to the weight detection module to trigger the weight detection module to detect the weight of the refrigerator.
[0015] In one embodiment, the switch detection module is a switch sensor.
[0016] In one embodiment, the refrigerator item detection device further includes a shock absorption module;

[0034] 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.
[0035] 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.
[0036] Based on this, the present invention provides a refrigerator item detection device. In the first embodiment of the present invention, please refer to... Figure 1 The refrigerator item detection device may include a weight detection module 10, a timing module 20, and an item storage reminder module 30; the weight detection module 10 is installed at the bottom of the refrigerator body, the input end of the timing module 20 is connected to the output end of the weight detection module 10, and the output end of the timing module 20 is connected to the input end of the item storage reminder module 30.
[0037] Weight detection module 10 is used to detect the weight of the refrigerator;
[0038] The timing module 20 is used to record the duration of the same refrigerator weight detected by the weight detection module 10, and when the duration reaches a preset time threshold, it outputs an electrical signal to the item storage reminder module 30 so as to transmit the refrigerator weight detected by the weight detection module 10 to the item storage reminder module 30 through the electrical signal.
[0039] The item storage reminder module 30 is used to receive electrical signals and remind users to store items when the weight of the refrigerator carried by the electrical signal exceeds a preset weight threshold.
[0040] It should be noted that the preset time threshold is used to determine whether the weight detection module has stably detected the weight of the refrigerator. It can be a default value, such as 10 seconds; or it can be flexibly set by the user according to the actual situation. This embodiment does not impose specific limitations on this. The preset weight threshold is used to determine whether there are items stored in the refrigerator. It can be a default value, such as the weight of the refrigerator itself; or it can be flexibly set by the user according to the actual situation. This embodiment does not impose specific limitations on this.
[0041] Additionally, it should be noted that the weight detection module 10 can be a gravity sensor, pressure sensor, capacitive weighing sensor, or other device or circuit with weight detection function, etc., and this embodiment does not specifically limit it. The timing module 20 can be a timer, time relay, or other device or circuit with timing function, etc., and this embodiment does not specifically limit it.
[0042] It is understandable that this embodiment is essentially for detecting the weight of a vehicle-mounted refrigerator. Therefore, the weight detection module 10 may experience a decrease in detection accuracy due to vehicle vibrations. Thus, to ensure accurate determination of whether items are stored inside the refrigerator, it can be configured so that the item storage reminder module 30 only compares the stable refrigerator weight detected by the weight detection module 10 with a preset weight threshold after the refrigerator weight detected by the weight detection module 10 has stabilized.
[0043] In one feasible implementation, the item storage reminder module 30 can be a controller, a microcontroller unit (MCU), or other control chip with control functions. Based on this, the item storage reminder module 30 can compare the refrigerator's weight with a preset weight threshold and provide reminders for item storage on the relevant control chip.
[0044] In another feasible implementation, please refer to Figure 2 The item storage reminder module 30 may include a comparator U1 and a reminder unit 31;
[0045] The positive input terminal of comparator U1 is connected to the output terminal of timing module 20, the negative input terminal of comparator U1 is connected to the preset weight threshold Vgset, and the output terminal of comparator U1 is connected to reminder unit 31.
[0046] The comparator U1 is used to: receive an electrical signal, compare the weight of the refrigerator carried by the electrical signal with the preset weight threshold Vgset, and when the weight of the refrigerator carried by the electrical signal is greater than the preset weight threshold Vgset, output a trigger signal to the reminder unit 31 to trigger the reminder unit 31 to remind the user to store items.
[0047] It should be noted that the reminder unit 31 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. In addition, the user's mobile device (such as a mobile phone, tablet computer, smartwatch, etc.) can also be used as the reminder unit 31. In this case, the output of the comparator U1 needs to be communicatively connected to the reminder unit 31, so that the reminder unit 31 can not only remind you to store items, but also remind you to leave items behind.
[0048] In the scenario where the reminder unit 31 provides an item forgetting reminder, the refrigerator item detection device may further include a distance detection module. This distance detection module can be installed on the comparator U1, with the output of the comparator U1 connected to the control terminal of the distance detection module. The output of the distance detection module is also connected to the reminder unit 31. This distance detection module, upon receiving an item storage signal from the comparator U1 (the comparator U1 outputs an item storage signal when the weight of the refrigerator carried by the electrical signal exceeds a preset weight threshold Vgset), detects the communication distance between the comparator U1 and the reminder unit 31. If the detected communication distance exceeds the preset distance threshold, it outputs a trigger signal to the reminder unit 31 to trigger the reminder unit 31 to provide an item forgetting reminder. In other words, for situations where the user leaves the vehicle but the refrigerator still contains items, an item forgetting reminder can be provided on the user's mobile device.
[0049] The distance detection module may include a distance detection unit (which may be a distance sensor or other device or circuit with distance detection function) and a second comparator (comparator U1 can be considered as the first comparator). The distance detection unit is mounted on comparator U1, the output of comparator U1 is connected to the control terminal of the distance detection unit, the output of the distance detection unit is connected to the positive input of the second comparator, the negative input of the second comparator is connected to a preset distance threshold, and the output of the second comparator is connected to the reminder unit 31. The distance detection unit is used to detect the communication distance between comparator U1 and the reminder unit 31 after receiving the item storage signal output by comparator U1. The second comparator is used to compare the communication distance detected by the distance detection unit with the preset distance threshold, and when the communication distance is greater than the preset distance threshold, it outputs a trigger signal to the reminder unit 31 to trigger the reminder unit 31 to remind the user of the item being left behind. The preset distance threshold is used as the basis for determining 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 it.
[0050] Additionally, it should be noted that when the weight of the refrigerator exceeds the preset weight threshold Vgset, the comparator U1 will output a high-level signal, which is the trigger signal output by the comparator U1 to the reminder unit 31.
[0051] This embodiment provides a refrigerator item detection device, which includes a weight detection module 10, a timing module 20, and an item storage reminder module 30. The weight detection module 10 is installed at the bottom of the refrigerator body and is used to detect the weight of the refrigerator. The input terminal of the timing module 20 is connected to the output terminal of the weight detection module 10, and the output terminal of the timing module 20 is connected to the input terminal of the item storage reminder module 30. The timing module 20 records the duration for which the weight detection module 10 detects the same refrigerator weight, and when the duration reaches a preset time threshold, it outputs an electrical signal to the item storage reminder module 30 to transmit the refrigerator weight detected by the weight detection module 10 to the item storage reminder module 30 through the electrical signal. The item storage reminder module 30 receives the electrical signal and reminds the user to store items when the refrigerator weight carried by the electrical signal is greater than the preset weight threshold.
[0052] Therefore, this embodiment uses a weight detection module 10 at the bottom of the refrigerator body to detect the refrigerator's weight, and a timing module 20 between the weight detection module 10 and the item storage reminder module 30 to record the duration for which the weight detection module 10 detects the same refrigerator weight. Thus, when the weight detection module 10 stably detects a certain refrigerator weight, the item storage reminder module 30 compares this stably detected weight with a preset weight threshold to accurately determine whether there are items stored in the refrigerator, and thus accurately determines whether to issue an item storage reminder. Therefore, this embodiment can accurately trigger a reminder mechanism when items are stored in the vehicle refrigerator, ensuring that users do not miss the items inside and effectively avoiding the problem of items remaining in the refrigerator for extended periods due to forgetfulness.
[0053] In addition, in other embodiments, the timing module in this embodiment can be replaced with a counting module to record the number of consecutive times the weight detection module detects the same refrigerator weight. When the number of consecutive times reaches a preset threshold, the counting module outputs an electrical signal to the item storage reminder module to transmit the refrigerator weight detected by the weight detection module to the item storage reminder module through the electrical signal.
[0054] The preset threshold number of times is used to determine whether the weight detection module has stably detected the weight of the refrigerator. It can be a default value, such as 10 times; or it can be flexibly set by the user according to the actual situation. This embodiment does not make a specific limitation on this. The counting module can be a counter or other devices or circuits with counting functions. This embodiment does not make a specific limitation on this.
[0055] Based on the first embodiment described above, a second embodiment of the refrigerator item detection device of this utility model is proposed. For the second embodiment, please refer to... Figure 3 The refrigerator item detection device may also include a switch detection module 40;
[0056] The switch detection module 40 is installed on the refrigerator door. The output of the switch detection module 40 is connected to the weight detection module 10 to detect the switch state of the refrigerator door. When the switch door is detected to be in the open state, the switch detection module 40 outputs a trigger signal to the weight detection module 10 to trigger the weight detection module 10 to detect the weight of the refrigerator.
[0057] It should be noted that the opening and closing state of the door can include both the open and closed states. The opening and closing detection module 40 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.
[0058] 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 40 on the refrigerator door to detect the open / closed state of the refrigerator door, so that when the switch detection module 40 detects that the door is open, it can trigger the weight detection module 10 to detect the weight of the refrigerator.
[0059] Based on this embodiment, the weight detection module 10 can also detect the weight of the refrigerator before the refrigerator door is opened. Therefore, by comparing the weight of the refrigerator detected by the weight detection module 10 before and after the refrigerator door is opened, it can be determined whether new items have been put into the refrigerator or whether items have been taken out of the refrigerator.
[0060] Based on the first and / or second embodiments described above, a third embodiment of the refrigerator item detection device of the present invention is proposed. In the third embodiment, the refrigerator item detection device may further include a shock-absorbing module 50, which is installed at the bottom of the refrigerator body.
[0061] It should be noted that the shock absorption module 50 can be used to offset the impact of vehicle bumps on the detection accuracy of the weight detection module 10. The shock absorption module 50 can be a shock absorber, rubber shock absorber pad, damper or other devices or circuits with shock absorption function. This embodiment does not make specific limitations on this.
[0062] In this embodiment, by installing a shock-absorbing module 50 at the bottom of the refrigerator body, the impact of vehicle bumps on the detection accuracy of the weight detection module 10 is further offset by the shock-absorbing module 50, thereby improving the detection accuracy of the weight detection module 10 when the vehicle is bumpy. This helps the refrigerator item detection device to more accurately determine whether there are items stored in the refrigerator, and to more accurately determine whether to remind the user to store items.
[0063] For example, the refrigerator item detection device obtained by combining the above embodiments can be referred to Figure 4 The form shown is provided on the refrigerator body of the vehicle refrigerator ( Figure 4 The main focus is on showing the placement of each module in the refrigerator's item detection device on the refrigerator body, so only the connections between some modules are displayed. The timing module 20 and the item storage reminder module 30 can be installed either on the outside or inside the vehicle refrigerator.
[0064] 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 detection device of the present invention. Any simple modifications based on this technical concept are within the protection scope of the present invention.
