[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0028] The following reference Figures 1 to 4 This invention describes a liquid level detection device 100 and a cooking device according to some embodiments of the present invention. The liquid level detection device 100 is applied to the cooking device, which may be a smart stir-fry machine, a smart ingredient dispensing machine, etc.

[0029] An embodiment of the first aspect of this utility model provides a liquid level detection device 100, comprising: a barrel assembly 110; a heating element 120 for heating the material inside the barrel assembly 110; a temperature regulating component 130 for storing the heat from the heating element 120 to maintain a constant temperature for the liquid; a temperature detection device 140 for detecting the temperature of the temperature regulating component 130; and a liquid level conversion device for converting temperature data into liquid level height; wherein the liquid level conversion device determines the change in the height of the material inside the barrel assembly 110 based on the temperature change of the temperature regulating component 130.

[0030] The container assembly 110 is used to hold materials, which can be liquid oil or a solid-liquid mixture. Specifically, this embodiment uses edible oil as an example. The oil contained in the container assembly 110 can be liquid oil, a solid-liquid mixture of oil, or solid grease. Specifically, because oil (such as edible oil) has a low freezing point, it easily solidifies in low-temperature environments. For example, in northern winters, edible oil is mostly a solid-liquid mixture or solid grease. It is understood that heating a solid-liquid mixture of oil or solid grease will melt the mixture or grease back into liquid oil and change the temperature of the liquid oil.

[0031] The liquid level detection device 100 provided in this embodiment includes a barrel assembly 110, a heating element 120, a temperature control component 130, a temperature detection device 140, and a liquid level conversion device. The heating element 120 heats the material inside the barrel assembly 110, ensuring that the material inside the barrel assembly 110 is in a liquid state. For example, it can heat and melt solid-liquid mixtures of oil or solid grease into liquid oil, which facilitates liquid level detection. The temperature control component 130 stores the heat generated by the heating element 120, keeping the liquid at a constant temperature, which prepares for subsequent liquid level detection based on temperature changes. The temperature of the temperature regulating component 130 is detected by the temperature detection device 140. Since the temperature of the temperature regulating component 130 is different in two states, namely when the liquid maintaining a constant temperature is immersed in the temperature regulating component 130 and when the liquid maintaining a constant temperature is lower than the temperature regulating component 130, the liquid level conversion device determines the change in the material level in the barrel component 110 based on the change in the detection result of the temperature detection device 140. That is, the liquid level conversion device can convert the detection result of the temperature detection device 140 into the detection of the liquid level height in the barrel component 110, thereby realizing the detection of the liquid level of the material in the barrel component 110.

[0032] In some embodiments, the temperature of the temperature control component 130 is detected by the temperature detection device 140. As the volume of the material in the barrel assembly 110 changes, the temperature of the temperature control component 130 also changes. Therefore, the liquid level conversion device determines the change in the level of the material in the barrel assembly 110 based on the change in the detection result of the temperature detection device 140.

[0033] The liquid level detection device 100 provided in this embodiment has a simple structure and does not require complex mechanical actions. Compared with the float movement used in related technologies to achieve liquid level detection, it avoids the problem of foreign objects getting stuck, which increases the friction of the float and prevents it from moving, thus causing the liquid level detection function to fail. At the same time, due to the setting of the heating element 120, the solid-liquid mixture of oil or solid grease can be heated and melted into liquid oil for liquid level detection. This avoids the problem in related technologies where the oil solidifies into grease, which increases the friction of the float and prevents it from moving, thus causing the liquid level detection function to fail. In other words, the liquid level detection device 100 provided in this embodiment can be adapted to different environmental requirements and can achieve liquid level detection for different states of oil, such as solid-liquid mixtures of oil, grease, and liquid oil. This improves the diversity of application scenarios and ensures the accuracy and stability of liquid level detection, making it suitable for widespread application.

[0034] In some possible embodiments provided by this utility model, the temperature regulating component 130 is at least partially in contact with the heating element 120, dispersing the heat generated by the heating element 120 into the liquid and / or solid.

[0035] In this embodiment, the temperature control component 130 is in contact with the heating element 120 at least partially, so that the temperature control component 130 can store the heat after the heating element 120 is heated more quickly and comprehensively, thereby improving the heat utilization rate of the heating element 120 and improving the efficiency of the liquid in the tank assembly 110 to reach a constant temperature, thereby improving the liquid level detection efficiency.

[0036] Specifically, the temperature regulating component 130 disperses the heat generated by the heating element 120 into the liquid and / or solid, thereby increasing the temperature of the liquid oil in the barrel assembly 110, or heating and melting the solid-liquid mixture of oil in the barrel assembly 110 into liquid, thus increasing the temperature of the liquid; or heating and melting the solid grease in the barrel assembly 110 into liquid, thus increasing the temperature of the liquid. In other words, by dispersing the heat generated by the heating element 120 into the liquid and / or solid through the temperature regulating component 130, the material in the barrel assembly 110 can be converted into a liquid, thus providing a convenient basis for subsequent liquid level detection and solving the problem of unusable solidified oil. Simultaneously, it maintains a constant temperature in the liquid within the barrel assembly 110, providing a basis for the subsequent liquid level detection device 100 to determine the liquid level changes in the barrel assembly 110 based on the temperature changes of the temperature regulating component 130, thereby achieving liquid level detection.

[0037] In this device, part of the temperature control component 130 can contact the heating element 120, while another part can not contact the heating element 120, or the entire temperature control component 130 can contact the heating element 120, in order to meet the needs of different structures of the temperature control component 130 and the heating element 120.

[0038] In some possible embodiments provided by this utility model, the heating element 120 is disposed on the bottom, top or side of the temperature regulating component 130 to meet the needs of different placement positions and different structures of the heating element 120 and the temperature regulating component 130.

[0039] It is understandable that the heating element 120 can be positioned on the bottom, top, side, or middle of the temperature control component without affecting its heating function or the liquid level detection device 100's function of detecting the liquid level. It is important to note that in practical applications, the heating element 120 needs to be immersed in the material, such as in oil, to prevent it from being exposed to air and burning out, thus extending its service life.

[0040] Furthermore, the heating element 120 is positioned on the bottom surface of the temperature control assembly 130. This effectively shields the heating element 120 from direct view by the user when observing the interior of the container assembly 110, improving the aesthetics of the interior and enhancing the user's visual experience. Simultaneously, this arrangement, placing the heating element 120 at the bottom of the container assembly 110, facilitates its immersion in the oil, providing excellent protection for the heating element 120.

[0041] In some possible embodiments provided by this utility model, the temperature control component 130 includes a heat-conducting element, which is laid flat on the bottom surface and / or side surface of the barrel assembly 110, and a gap is provided between the heat-conducting element and the bottom surface of the barrel assembly 110.

[0042] The heat-conducting component can store the heat generated by the heating element 120 and transfer it to the liquid, keeping the liquid at a constant temperature. Specifically, the heat-conducting component can be a heat-conducting aluminum plate or other structures.

[0043] By laying the heat-conducting components flat on the bottom and / or sides of the barrel assembly 110, making the heat-conducting components roughly plate-shaped, the contact area between the heat-conducting components and the material inside the barrel can be increased, thereby improving the heat conduction efficiency of the heat-conducting components. This is beneficial for the material inside the barrel assembly 110 to quickly melt into a liquid state, and / or for the temperature of the liquid oil to rise rapidly, thereby improving the efficiency of reaching a constant temperature state, and improving the durability, stability and uniformity of the oil in maintaining a constant temperature state.

[0044] By setting a gap between the heat-conducting component and the bottom surface of the barrel assembly 110, the oil can be contained in the gap between the heat-conducting component and the bottom surface of the barrel assembly 110, so as to facilitate low liquid level detection. At the same time, the oil can soak the heating element 120 located at the bottom of the heat-conducting component through the gap, which can play a good protective role for the heating element 120 and prevent the heating element 120 from dry burning.

[0045] Specifically, such as Figure 1 and Figure 3 As shown, a support portion 133 is provided on the side of the heat-conducting component facing the bottom surface of the barrel assembly 110, so that a gap is formed between the heat-conducting component and the bottom surface of the barrel assembly 110, allowing oil to pass through the gap and immerse the heating element 120 located on the side of the heat-conducting component facing the bottom surface of the barrel assembly 110. It is understood that the number of support portions 133 can be one or more.

[0046] Furthermore, the heat-conducting component can be laid flat on the bottom surface of the barrel assembly 110, or the heat-conducting component can be laid flat on the side surface of the barrel assembly 110, or the heat-conducting component can be laid flat on both the bottom and side surfaces of the barrel assembly 110.

[0047] Specifically, the heating element 120 can be detachably connected to the heat-conducting element to facilitate disassembly and separation of the heating element 120 and the heat-conducting element for maintenance and replacement. Specifically, the heating element 120 can be installed on the heat-conducting element through at least one of the following: snap-fit ​​structure, plug-in structure, tenon and mortise structure, and adhesive.

[0048] Specifically, the heating element 120 can be embedded at the bottom of the heat-conducting element, that is, the heat-conducting element wraps around the heating element 120 from the top and sides to increase the contact area between the heat-conducting element and the heating element 120, increase the heat conduction area of ​​the heat-conducting element, so as to improve the efficiency of the material in the barrel assembly 110 melting into liquid, and / or improve the efficiency of the liquid in the barrel assembly 110 reaching a constant temperature state.

[0049] In some possible embodiments provided by this utility model, the temperature detection device 140 is at least partially in contact with the temperature control component 130.

[0050] The temperature detection device 140 is used to detect the temperature of the temperature control component 130. By having at least a portion of the temperature detection device 140 in contact with the temperature control component 130, the sensitivity and accuracy of the temperature detection device 140 in detecting the temperature of the temperature control component 130 can be ensured, thereby improving the sensitivity and accuracy of the liquid level detection.

[0051] The temperature detection device 140 can be a temperature sensor, such as a probe. Specifically, the temperature detection device 140 can contact the temperature control component 130, such as the probe of a probe contacting the temperature control component 130. Since the material inside the barrel assembly 110 is kept at a constant temperature by the heating element 120 and the temperature control component 130, when the constant-temperature liquid is immersed in or in contact with the temperature control component 130, the temperature of the temperature control component 130 will be approximately the same as or have a small temperature difference with the constant-temperature liquid. When the liquid level is low, such as when the liquid level is below the temperature control component 130, the temperature of the temperature control component 130 will rise. At this time, the temperature information detected by the temperature detection device 140 shows a difference, indicating that the liquid level inside the barrel assembly 110 has changed, i.e., the liquid level inside the barrel assembly 110 is low, below the temperature control component 120, thus realizing the liquid level detection function of the material inside the barrel assembly 110.

[0052] In some embodiments, the temperature detection device 140 can be a temperature sensor, such as a probe. Specifically, the temperature detection device 140 can be in contact with the temperature control component 130, such as the probe of a probe being in contact with the temperature control component 130. Since the heating component 120 stops working after the material in the barrel assembly 110 is kept at a constant temperature by the heating element 120 and the temperature control component 130, the temperature detection device 140 detects the temperature of the temperature control component 130. When the volume of the material in the barrel assembly 110 decreases, the temperature of the liquid in the barrel assembly 110 will decrease, and the temperature of the temperature control component 130 immersed in the material will also decrease synchronously. That is, the temperature detection device 140 indirectly detects the temperature of the liquid in the barrel assembly 110, so the change in the height of the liquid in the barrel assembly 110 can be determined by the temperature detected by the temperature detection device 140. When the liquid level in the barrel assembly 110 is lower than that in the temperature control assembly 130, the heating element 130 will restart heating because the temperature detected by the temperature detection device 140 is lower than the threshold. At this time, the temperature detection device 140 detects the temperature of the heating element 120. Therefore, when the temperature detected by the temperature detection device 140 suddenly rises from low, it indicates that the liquid level of the material in the barrel assembly 110 is low, thus realizing the liquid level detection function of the material in the barrel assembly 110.

[0053] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some possible embodiments provided by this utility model, the heat-conducting component includes a first heat-conducting part 131 disposed on the bottom surface of the barrel assembly 110 and a second heat-conducting part 132 located on the top of the first heat-conducting part 131. The first heat-conducting part 131 and the second heat-conducting part 132 are detachably or fixedly connected.

[0054] In this embodiment, the first heat-conducting part 131 can be understood as being laid flat on the bottom surface of the barrel assembly 110, and the second heat-conducting part 132 can be opposite to the side surface of the barrel assembly 110. By setting the first heat-conducting part 131 and the second heat-conducting part 132, the heat-conducting area of ​​the heat-conducting component can be increased, thereby increasing the contact area between the oil in the barrel assembly and the heat-conducting component, thereby increasing the efficiency of the material in the barrel assembly 110 melting into liquid, and / or increasing the efficiency of the liquid in the barrel assembly 110 reaching a constant temperature state, and is conducive to improving the durability of the constant temperature state of the liquid.

[0055] The first heat-conducting part 131 and the second heat-conducting part 132 can be detachably connected, for example, by at least one of the following methods: bolt structure, snap-fit ​​structure, plug-in structure, tenon structure, and magnetic structure. Alternatively, the first heat-conducting part 131 and the second heat-conducting part 132 can be fixedly connected, for example, by welding or bonding. It is understood that in other examples, the first heat-conducting part 131 and the second heat-conducting part 132 can be an integral structure, such as a one-piece molded structure.

[0056] like Figure 3 As shown, in some possible embodiments provided by this utility model, the temperature detection device 140 includes a first temperature sensor 141, the probe of the first temperature sensor 141 is inserted into the second heat-conducting part 132 and contacts the second heat-conducting part 132 and / or the first heat-conducting part 131.

[0057] In this embodiment, the probe of the first temperature sensor 141 is inserted into the second heat-conducting part 132, so that the second heat-conducting part 132 provides a mounting structure and mounting position for the first temperature sensor 141, simplifying the setting of the mounting structure of the first temperature sensor 141 and meeting the design requirements of compact structure and small size of liquid level detection device 100. The probe of the first temperature sensor 141 contacts the first heat-conducting part 131 and / or the second heat-conducting part 132 to ensure that the first temperature sensor 141 can detect the temperature of the temperature control component 130 in a timely, accurate, and sensitive manner.

[0058] Specifically, the probe of the first temperature sensor 141 can contact the first heat-conducting part 131, or the probe of the first temperature sensor 141 can contact the second heat-conducting part 132, or the probe of the first temperature sensor 141 can contact the first heat-conducting part 131 and the second heat-conducting part 132.

[0059] Understandably, the specific position of the probe of the first temperature sensor 141 on the heat-conducting component can be reasonably set according to the liquid level detection device 100's requirements for detecting high and low liquid levels.

[0060] like Figure 3 As shown, in some possible embodiments provided by this utility model, the temperature detection device 140 includes a second temperature sensor 142, which is spaced apart from the temperature control component 130. The second temperature sensor 142 is used to detect the material temperature inside the barrel component 110.

[0061] In other words, the second temperature sensor 142 is not in contact with the temperature control component 130; the two are arranged at an interval. The second temperature sensor 142 is used to detect the temperature of the material inside the container. Thus, in a practical scenario, when the constant-temperature liquid level inside the container assembly 110 is low, such as below the level of the first temperature sensor 141 and the second temperature sensor 142, since the second temperature sensor 142 is not in contact with the temperature control component 130 or the liquid, while the first temperature sensor 141 is in contact with the temperature control component 130, there will be a difference in the temperatures detected by the first temperature sensor 141 and the second temperature sensor 142. The temperature detected by the first temperature sensor 141 will be higher than the temperature detected by the second temperature sensor 142. Therefore, it can be determined that the liquid level inside the container assembly 110 is lower than that of the second temperature sensor 142, thus realizing the liquid level detection function inside the container assembly 110.

[0062] Specifically, the first temperature sensor 141 and the second temperature sensor 142 can be the same detection structure or different detection structures. Specifically, both the first temperature sensor 141 and the second temperature sensor 142 can be probes.

[0063] like Figure 3 As shown, in some possible embodiments provided by this utility model, the probe of the second temperature sensor 142 is positioned further away from the bottom surface of the barrel assembly 110 than the temperature control assembly 130.

[0064] In this configuration, the bottom surface of the temperature control component 130 is close to and opposite to the bottom surface of the tank assembly 110. The probe of the second temperature sensor 142 is farther away from the bottom surface of the tank assembly 110 relative to the bottom surface of the temperature control component 130, meaning the probe of the second temperature sensor 142 is higher than the bottom surface of the temperature control component 130. This arrangement ensures that when the liquid level inside the tank assembly 110 is lower than the probe of the second temperature sensor 142, a temperature difference will be detected by the first temperature sensor 141 and the second temperature sensor 142, thus achieving liquid level detection. Specifically, the liquid level at this time can be a low liquid level threshold. Meanwhile, the liquid level inside the tank assembly 110 can be lower than the probe of the second temperature sensor 142 but higher than the bottom surface of the temperature control component 130, allowing the oil to immerse the heating element 120 located at the bottom surface of the temperature control component 130, preventing the heating element 120 from dry-burning and providing good protection for it.

[0065] Understandably, when the temperature sensor includes only the first temperature sensor 141 and excludes the second temperature sensor 142, the probe of the first temperature sensor 141 can be set to be farther from the bottom surface of the tank assembly 110 than the temperature control component 130, i.e., the probe of the first temperature sensor 141 is higher than the bottom surface of the temperature control component 130. In this way, when the liquid level in the tank assembly 110 is lower than the probe of the first temperature sensor 141, the temperature detected by the first temperature sensor 141 will show a difference, thus realizing the liquid level detection function. At this time, the liquid level in the tank assembly 110 can be lower than the probe of the first temperature sensor 141 but higher than the bottom surface of the temperature control component 130, so that the oil can immerse the heating element 120 located on the bottom surface of the temperature control component 130, preventing the heating element 120 from dry burning and providing good protection for the heating element 120.

[0066] like Figure 1 and Figure 4 As shown, in some possible embodiments provided by this utility model, the liquid level detection device 100 further includes a control device, which is electrically connected to the heating element 120. The control device is configured to control the working state of the heating element 120 based on the detection information from the temperature detection device 140. This enables the heating element 120 to accurately melt the material in the barrel assembly 110 into a liquid state and maintain it at a constant temperature, thereby improving the accuracy of the liquid level conversion device in judging the height change of the material in the barrel assembly 110 based on the temperature change of the temperature regulating component 130, and further improving the detection accuracy of the liquid level detection device 100.

[0067] Specifically, the heating element 120 can be a heating wire, a heating tube, or other heating element.

[0068] In some possible embodiments provided by this utility model, the control device is configured to control the working state of the heating element 120 according to the detection information of the temperature detection device 140. Specifically, it includes: when the detection information of the temperature detection device 140 is less than a first preset temperature, controlling the heating element 120 to start working; when the detection information of the temperature detection device 140 reaches a second preset temperature, controlling the heating element 120 to stop working so that the liquid is kept at a constant temperature. The first preset temperature is less than the second preset temperature, and the second preset temperature can be understood as the temperature of the temperature regulating component 130 when the liquid in the tank assembly 110 is kept at a constant temperature.

[0069] In this embodiment, the temperature detection device 140 is used to detect the temperature of the temperature regulating component 130. When the detection information of the temperature detection device 140 is lower than the first preset temperature, it indicates that the temperature of the temperature regulating component 130 is low. At this time, the liquid in the barrel assembly 110 has not reached the temperature of a constant temperature state. The control device controls the heating element 120 to work, storing the heat after heating by the heating element 120 through the temperature regulating component 130, and melting the solid-liquid mixture or solid grease in the barrel assembly 110 into liquid oil, and heating the liquid oil, or directly heating the liquid oil in the barrel assembly 110. When the detection information of the temperature detection device 140 reaches the second preset temperature, it indicates that the temperature regulating component 130 has reached the temperature required for the liquid to maintain a constant temperature, that is, the liquid in the barrel assembly 110 has reached the temperature required for a constant temperature state. At this time, the heating element 120 is controlled to stop working, so that the liquid maintains a constant temperature state.

[0070] The first preset temperature can be less than 40°C, and the second preset temperature can be 65°C to 75°C, such as 70°C.

[0071] The first preset temperature can be greater than or equal to 40℃ and less than 50℃, and the second preset temperature can be 52℃ to 55℃, such as 53℃.

[0072] like Figure 1 and Figure 4 As shown, in some possible embodiments of this invention, the liquid level detection device 100 further includes a liquid pipeline 150, which passes through the temperature control assembly 130. Therefore, the temperature control assembly 130 can be used to heat and melt the solid-liquid mixture or solid grease remaining in the liquid pipeline 150, reducing the risk of blockage and improving its smoothness. Simultaneously, this arrangement allows the temperature control assembly 130 to shield and protect the liquid pipeline 150, improving the aesthetics of the interior of the tank assembly 110. It also prevents the liquid pipeline 150 from being exposed inside the tank assembly 110 and potentially being scratched by other components, thus extending its service life.

[0073] Specifically, the liquid pipeline 150 can connect the inside and outside of the tank assembly 110. For example, the liquid inside the tank assembly 110 can be transported to the outside of the tank assembly 110 through the liquid pipeline 150. By passing through the temperature control component 130 through the liquid pipeline 150, the risk of blockage of the liquid pipeline 150 can be reduced, thereby ensuring the smooth flow of liquid inside the tank assembly 110 to the outside through the liquid pipeline 150.

[0074] like Figure 1As shown, in some possible embodiments provided by this utility model, the liquid level detection device 100 further includes a filter device 180. The filter device 180 is located at the bottom of the temperature control component 130 and is sleeved on the periphery of the end of the liquid pipeline 150 located inside the barrel assembly 110. The filter device 180 is provided with a plurality of filter holes for filtering impurities in the oil. For example, the liquid pipeline 150 includes a first end and a second end. The first end is located inside the barrel assembly 110, and the second end is located outside the barrel assembly 110. The filter device 180 is located on the periphery of the first end to filter the liquid flowing into the liquid pipeline 150 through the first end, reducing the possibility of impurities flowing into the first end and causing blockage of the liquid pipeline 150. At the same time, it helps to improve the cleanliness of the liquid flowing through the liquid pipeline 150.

[0075] Specifically, the filter device 180 can be detachably installed at the bottom of the heat-conducting component, such as by at least one of the following methods: bolt structure, snap-fit ​​structure, tenon structure, or magnetic structure. Alternatively, the filter device 180 can also be installed on the bottom surface inside the tank assembly 110. When the temperature control assembly 130 is placed inside the tank assembly 110, the first end of the liquid pipeline 150 can be inserted into the filter device 180.

[0076] like Figure 1 and Figure 4 As shown, in some possible embodiments provided by this utility model, the liquid level detection device 100 further includes: a prompting device 160, which is connected to the control device and is used to prompt the feedback signal of the temperature detection device 140. That is, when the liquid level conversion device determines the change in the material level in the tank assembly 110 based on the temperature change of the temperature regulating component 130, the control device prompts the feedback signal through the prompting device 160 to remind the user that the liquid in the tank assembly 110 has reached the preset liquid level. If the liquid level is low, the user is prompted to replenish the material in time.

[0077] The control device and the prompting device 160 are integrated into the housing 170. The housing 170 provides installation space and position for the control device and the prompting device 160, and at the same time, it provides good protection for the control device and the prompting device 160, which helps to extend the service life of the control device and the prompting device 160.

[0078] The temperature control component 130 is located outside the housing 170 and connected to the housing 170 to facilitate the circuit connection between the temperature detection device 140 installed on the temperature control component 130 and the control device circuit inside the housing 170.

[0079] The prompting device 160 includes at least one of an audio prompting device 160, an LED prompting device 160, and a text prompting device 160, such as a buzzer, an indicator, or a display screen.

[0080] A second aspect of this utility model provides a cooking device, including: a main body of the device and a liquid level detection device 100 of any embodiment in the first aspect, and a container assembly 110 for containing oil or a solid-liquid mixture. Since the cooking device includes the liquid level detection device 100 of any of the aforementioned embodiments, it possesses all the technical effects of the aforementioned liquid level detection device 100, which will not be elaborated further here.

[0081] Furthermore, the liquid level detection device 100 is installed on the main body of the equipment. For example, the tank assembly 110 of the liquid level detection device 100 is installed on the main body of the equipment. The tank assembly 110 is used to contain oil or solid-liquid mixtures to realize the containment of liquid seasonings or edible oils. In addition, the liquid level detection device 100 can detect the low liquid level of the liquid seasonings in the tank assembly 110, so as to remind the user to replenish the material in time through the prompting device 160.
