Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Hereinafter, embodiments will be described with reference to the accompanying drawings, which are not intended to limit the disclosure described in the claims.

[0031] Example 1:

[0032] Please see Figure 1 The following is combined with Figure 1 A detailed description of a fuel level reminder device provided in the embodiments of this application will be given.

[0033] Specifically, embodiments of this application provide a fuel level reminder device, such as... Figure 1 As shown, the fuel level reminder device includes a fuel level detection module and a display and control module, and the fuel level detection module and the display and control module are electrically connected.

[0034] The oil level detection module includes a communication tag reading unit 1, a communication tag 2, and an elastic component. The communication tag reading unit 1 is installed on the oil cup base 4 in the range hood, and the communication tag 2 is installed at the bottom of the oil cup 5. There is a preset interval between the oil cup base 4 and the oil cup 5. The communication tag reading unit 1 and the communication tag 2 are arranged opposite to each other. One end of the elastic component is connected to the bottom of the oil cup 5, and the other end of the elastic component is connected to the oil cup base 4. When the oil cup 5 drives the elastic component to move a first distance toward the oil cup base 4, the communication tag reading unit 1 and the communication tag 2 establish a communication connection and trigger a communication reminder signal. The communication tag reading unit 1 transmits the communication reminder signal to the display and control module so that the display and control module can remind the user of the oil level.

[0035] In this embodiment of the application, the oil level reminder device is a reminder device for the amount of oil in the oil cup 5. That is, when the amount of oil in the oil cup 5 reaches the preset amount, a corresponding reminder signal can be output to remind the user to pour out the oil accumulated in the oil cup 5. Thus, even if the user cannot observe the amount of oil accumulated in the oil cup 5, the oil level in the oil cup 5 can be accurately detected.

[0036] In one specific embodiment, the oil level detection module is used to detect the oil level in the oil cup 5. In some embodiments, such as... Figure 1As shown, the fuel level detection module includes a communication tag reading unit 1, a communication tag 2, and a flexible component. The communication tag reading unit 1 is a unit for reading the communication tag 2. For example, the communication tag reading unit 1 can be a Near Field Communication (NFC) card reader, and thus, the communication tag reading unit 1 is a contactless card reader. The communication tag 2 is a passive device based on near field communication technology, which can store information and communicate with the communication tag reading unit 1 at close range to achieve rapid data exchange or signal identification. For example, the communication tag 2 can be an NFC tag. The flexible component is a component structure with elasticity.

[0037] Specifically, the elastic component is positioned between the oil cup base 4 and the oil cup 5. As the amount of oil in the oil cup 5 increases, the oil cup 5 can drive the elastic component to move towards the oil cup base 4. When the oil cup 5 drives the elastic component to move a first distance towards the oil cup base 4, the communication tag reading unit 1 positioned on the oil cup base 4 and the communication tag 2 positioned at the bottom of the oil cup 5 can communicate. That is, the NFC card reader can read the information of the communication tag 2, which means that the NFC card reader can read the signal. Consequently, the communication tag reading unit 1 can trigger a communication reminder signal and transmit the communication reminder signal to the display and control module, so that the display and control module can provide an oil level reminder. This can improve the accuracy of detecting the oil level in the oil cup 5, so that when the oil level in the oil cup 5 reaches the preset amount, the user can be promptly reminded to clean the oil stains in the oil cup 5.

[0038] It should be noted that when the oil cup 5 drives the elastic component to move a first distance toward the oil cup base 4, it indicates that the oil level in the oil cup 5 has reached the preset oil level threshold. That is, the amount of oil accumulated in the oil cup 5 is enough to cause the oil cup 5 to drop a first distance, which in turn drives the communication tag 2 at the bottom of the oil cup 5 to drop a first distance as well. At this time, the communication tag reading unit 1 and the communication tag 2 can communicate. That is, the communication tag reading unit 1 can read the signal of the communication tag 2 and generate a communication reminder signal so as to transmit the communication reminder signal to the display and control module.

[0039] In one alternative implementation, such as Figure 1 As shown, the elastic component includes a first elastic element 31 and a second elastic element 32; wherein, one end of the first elastic element 31 is connected to the bottom of the oil cup 5, and the other end of the first elastic element 31 is connected to the oil cup base 4; one end of the second elastic element 32 is connected to the bottom of the oil cup 5, and the other end of the second elastic element 32 is connected to the oil cup base 4; the first elastic element 31 and the second elastic element 32 are respectively located at both ends of the oil cup base 4.

[0040] In this embodiment, both the first elastic element 31 and the second elastic element 32 can be springs. Furthermore, by providing the first elastic element 31 and the second elastic element 32 between the oil cup 5 and the oil cup base 4, and with the first elastic element 31 and the second elastic element 32 located at both ends of the oil cup base 4 respectively, it is possible to move the first distance toward the oil cup base 4 with the help of the elastic elements to determine the distance the oil cup 5 descends. At the same time, it is also possible to make the two ends of the oil cup 5 descend the same distance, thereby ensuring the stability of the oil cup 5.

[0041] It should be noted that the deformation of the spring is equal to the distance that the oil cup 5 descends.

[0042] In one specific embodiment, the communication tag reading unit 1 is located in the middle of the oil cup base 4, the communication tag 2 is located in the middle of the bottom of the oil cup 5, and the size of the oil cup base 4 matches the bottom size of the oil cup 5.

[0043] Specifically, by placing the communication tag reading unit 1 in the middle of the oil cup base 4 and the communication tag 2 in the middle of the bottom of the oil cup 5, the communication tag reading unit 1 and the communication tag 2 can communicate.

[0044] In practical applications, the length of the oil cup base 4 is equal to the length of the bottom of the oil cup 5.

[0045] In one specific implementation, the communication tag reading unit 1 is a contact reader or a contactless reader. Preferably, the communication tag reading unit 1 is a contactless reader. For example, the communication tag reading unit 1 is an NFC reader.

[0046] The working principle of oil quantity detection using communication tag reading unit 1, communication tag 2, and elastic component is described below.

[0047] Assuming the spring constant is k, then according to Hooke's Law, the spring force F = kx, where x is the deformation of the spring. If the maximum oil capacity of oil cup 5 is m, then the gravitational force generated by oil cup 5 is G = mg, where g is the acceleration due to gravity, which is a constant. Therefore, the spring force F = G. Since the two springs are subjected to horizontal forces, the force on each spring is G / 2. From this, we can derive: 2kx = mg, and further, x = mg / 2k, where g and k are constants. Therefore, as the oil capacity of oil cup 5 increases, the larger x becomes, and the smaller the distance between oil cup 5 and oil cup base 4 becomes.

[0048] If the effective reading distance of the NFC reader (the distance the oil level drops when the oil level in the oil cup 5 reaches the preset oil level threshold) is a, and the distance between the empty oil cup 5 and the oil cup base 4 is y, then when y-mg / 2k=a, the communication tag reading unit 1 can trigger a communication reminder signal, i.e., an NFC signal, and transmit the communication reminder signal to the display and control module so that the display and control module can remind the user. The specific reminder method can be a voice reminder, an audible reminder, or a flashing light reminder, etc.

[0049] It should be noted that the preset oil level threshold can be 80% of the oil level in oil cup 5 when it is full, 90% of the oil level in oil cup 5 when it is full, or the oil level in oil cup 5 when it is full, etc.

[0050] The above embodiments of this application have the following beneficial effects:

[0051] This application includes an oil level detection module comprising a communication tag reading unit, a communication tag, and an elastic component. When the oil cup drives the elastic component to move a first distance toward the oil cup base, the communication tag reading unit triggers a communication reminder signal and transmits the signal to the display and control module. This allows the display and control module to provide an oil level reminder, thereby improving the accuracy of oil level detection in the oil cup. When the oil level in the oil cup reaches a preset amount, the user is promptly reminded to clean the oil from the cup.

[0052] Example 2:

[0053] Please see Figure 2 The following is combined with Figure 2 The oil level reminder device with a Hall effect detection unit and a magnetic object provided in the embodiments of this application will be described in detail.

[0054] Specifically, embodiments of this application provide a fuel level reminder device, such as... Figure 2 As shown, the fuel level reminder device includes a fuel level detection module and a display and control module, and the fuel level detection module and the display and control module are electrically connected.

[0055] The oil level detection module includes a Hall effect sensor 6 and a magnetic object 7. The Hall effect sensor 6 is electrically connected to the display and control module. The Hall effect sensor 6 is located on the side wall of the oil cup 5, and the magnetic object 7 is located inside the oil cup 5 and fixed to a float 8 inside the oil cup 5. The magnetic object 7 fixed to the float 8 can move with the change of oil level in the oil cup 5. The movement of the magnetic object 7 can cause the Hall effect sensor 6 to transmit a Hall voltage corresponding to the oil level to the display and control module. The display and control module is used to issue an oil level reminder signal when the difference between the Hall voltage and the initial Hall voltage is greater than a preset voltage difference threshold.

[0056] In this embodiment, the Hall detection unit 6 can be a Hall sensor, and the magnetic object 7 is a magnetic object. For example, the magnetic object 7 can be a magnet. Furthermore, by fixing the magnetic object 7 to the float 8 inside the oil cup 5, the float 8 carries the magnetic object 7 and floats on the oil in the oil cup 5. When the oil level in the oil cup 5 rises or falls, the height of the magnetic object 7 changes. The Hall sensor can then output a Hall voltage corresponding to the oil level in the oil cup 5. The display and control module can then determine whether an oil level reminder is needed by comparing the difference between the Hall voltage output by the Hall sensor corresponding to the oil level and the initial Hall voltage. This improves the detection accuracy, increases the response speed, and reduces production costs.

[0057] It should be noted that the initial Hall voltage is the Hall voltage output by the Hall sensor when the magnetic object 7 is located at the bottom of the oil cup 5, that is, the Hall voltage when there is no oil accumulation in the oil cup 5.

[0058] In another specific embodiment, the magnetic object 7 can also be a magnetic float, wherein a magnetic float is a device that can float in a liquid. Therefore, when the magnetic object 7 is a magnetic float, it is not necessary to fix the magnetic object 7 to the float 8. That is, the magnetic object 7, which is a magnetic float, can float on the oil in the oil cup 5 by itself.

[0059] In one optional embodiment, the Hall detection unit 6 is located at the bottom of the side wall of the oil cup 5. In another specific embodiment, the Hall detection unit 6 is located in the middle of the side wall of the oil cup 5. In yet another specific embodiment, the Hall detection unit 6 is located at the top of the side wall of the oil cup 5. Preferably, the Hall detection unit 6 is located at the bottom of the side wall of the oil cup 5.

[0060] The working principle of oil quantity detection using Hall effect detection unit 6 and magnetic object 7 is described below.

[0061] By mounting a Hall sensor on the side wall of the oil cup 5 to ensure that the sensitive surface of the Hall sensor can detect the magnet, a magnet is placed in the oil cup 5 and fixed to a float. The float carrying the magnet can then move up and down with changes in the oil level. When the oil level changes, the change in the position of the magnet causes a change in the Hall voltage output by the Hall sensor. The Hall voltage output by the Hall sensor is sent to the display and control module, which determines the oil level based on the difference between the Hall voltage and the initial Hall voltage. When the oil level reaches a preset height threshold, a fuel level reminder signal is issued. Specifically, if the display and control module detects that the difference between the Hall voltage and the initial Hall voltage is greater than the preset voltage difference threshold, it indicates that the oil level in the oil cup 5 has reached the preset height threshold, and a fuel level reminder signal can be issued. The specific reminder method can be a voice reminder, an audible reminder, or a flashing light reminder.

[0062] The above embodiments of this application have the following beneficial effects:

[0063] This application determines whether an oil level warning is needed by using the relationship between the Hall voltage output by the Hall sensor corresponding to the oil level and the initial Hall voltage. This improves detection accuracy, response speed, and reduces production costs.

[0064] Example 3:

[0065] Please see Figure 3 The following is combined with Figure 3 The oil level reminder device of the weighing unit provided in the embodiments of this application will be described in detail.

[0066] Specifically, embodiments of this application provide a fuel level reminder device, such as... Figure 3 As shown, the fuel level reminder device includes a fuel level detection module and a display and control module, and the fuel level detection module and the display and control module are electrically connected.

[0067] The oil level detection module includes a weighing unit 9, which is electrically connected to the display and control module. The oil cup 5 is located on the weighing surface of the weighing unit 9, and the weighing unit 9 is set on the oil cup base 4. The weighing unit 9 is used to weigh the oil cup 5 and transmit the weighing data to the display and control module. The display and control module is used to issue an oil level reminder signal when the weighing data is greater than the preset weighing threshold.

[0068] In this embodiment, the weighing unit 9 can be a weighing sensor, which weighs the oil cup 5 and the amount of oil accumulated in the oil cup 5 to obtain weighing data. The obtained weighing data is then sent to the display and control module, so that the display and control module can issue an oil level reminder signal when the weighing data is greater than a preset weighing threshold, so as to remind the user to clean the oil stains in the oil cup 5 in a timely manner.

[0069] It should be noted that when the weighing data is greater than the preset weighing threshold, it indicates that the oil in oil cup 5 needs to be cleaned. Then the display and control module can send an oil level reminder signal to remind the user to empty the oil in oil cup 5. Thus, even if the user cannot observe how much oil is in oil cup 5, the oil level in oil cup 5 can still be accurately detected.

[0070] The above embodiments of this application have the following beneficial effects:

[0071] This application uses a weighing unit to weigh the oil cup and transmits the weighing data to the display and control module. When the weighing data exceeds a preset weighing threshold, the display and control module issues an oil level reminder signal to promptly remind the user to clean the oil in the oil cup.
