[0065] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0066] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0067] The following describes an intelligent control method for a check valve according to this application. Figure 1This is a flowchart illustrating an intelligent control method for a check valve provided in an embodiment of this specification. This specification provides the operational steps of the method described in the embodiment or flowchart, but based on conventional or non-inventive methods, more or fewer operational steps may be included. The order of steps listed in the embodiment is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the method can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment) as shown in the embodiment or accompanying drawings. Specifically, as... Figure 1 As shown, the method may include:

[0068] S01: Obtain the historical heating power corresponding to the historical oil condensation degree during the historical operation of the range hood; the historical heating power is the heating power that makes the historical oil condensation degree reach the preset condensation degree, and the preset condensation degree is used to characterize that the oil condensation is in a melted state.

[0069] In this embodiment, an oil stain detection device can be installed inside the range hood to obtain the heating power corresponding to various oil stain solidification degrees (oil stain hardness) during the historical operation of the range hood. This heating power is the heating power that can melt the oil stain and change the check valve from the closed state to the open state.

[0070] In this embodiment, a heating module can be installed on the check valve to heat it. By adjusting the heating power of the heating module, the check valve can be heated at different power levels, thereby softening the grease on the check valve and making it easier for the check valve to be quickly blown open by the air in the range hood duct, preventing the backflow of fumes and ensuring the effectiveness of the range hood.

[0071] S02: Based on the correspondence between the historical oil contamination degree and the historical heating power, a preset heating power database is obtained.

[0072] In this embodiment, a preset heating power database is established based on the correspondence between historical oil condensation levels and historical heating power. This allows for the rapid and accurate determination of the appropriate heating power after the range hood is started, based on the oil condensation level. This effectively ensures the control precision of the check valve heating and improves the working efficiency of the range hood.

[0073] S03: When the range hood is detected to be started, the current degree of oil condensation on the check valve in the range hood is obtained.

[0074] S04: Search the preset heating power database for a preset heating power that matches the current oil congealing degree, and obtain the target heating power corresponding to the current oil congealing degree.

[0075] S05: Determine the target power range corresponding to the target heating power, and determine the target heating mode corresponding to the target power range according to the correspondence between the preset heating mode and the preset power range.

[0076] In one exemplary embodiment, such as Figure 2 As shown, the preset heating mode includes a first heating mode and a second heating mode, wherein the heating intensity of the first heating mode is greater than the heating intensity of the second heating mode, and the method may further include:

[0077] S051: Based on the heating intensity of the first heating mode, determine the preset power range corresponding to the first heating mode, which is the first preset power range;

[0078] S052: Based on the heating intensity of the second heating mode, determine the preset power range corresponding to the second heating mode as the second preset power range; the first preset power range is a range greater than a preset power threshold, and the second preset power range is a range less than or equal to the preset power threshold;

[0079] S053: Based on the correspondence between the first heating mode and the first preset power range, and the correspondence between the second heating mode and the second preset power range, the correspondence between the preset heating mode and the preset power range is obtained.

[0080] In this embodiment, the heating mode of the check valve in the range hood can be set to two levels. The first heating mode can be a high-efficiency heating mode, and the second heating mode can be a running heating mode. The heating intensity of the first heating mode is greater than that of the second heating mode.

[0081] In this embodiment of the application, a preset power range corresponding to the first heating mode is determined based on the heating intensity of the first heating mode, which is the first preset power range; a preset power range corresponding to the second heating mode is determined based on the heating intensity of the second heating mode, which is the second preset power range; wherein, the first preset power range is a range greater than a preset power threshold, and the second preset power range is a range less than or equal to the preset power threshold.

[0082] In this embodiment, after obtaining the first preset power range and the second preset power range, the correspondence between the preset heating mode and the preset power range can be obtained based on the correspondence between the first heating mode and the first preset power range, and the correspondence between the second heating mode and the second preset power range. Once the target power range corresponding to the target heating power is confirmed, the corresponding heating mode can be quickly and accurately determined, thereby heating the check valve.

[0083] In this embodiment, in addition to the two heating modes mentioned above, two or more heating modes can be set according to actual needs to obtain a more detailed preset power range, so as to heat the check valve with a more suitable heating mode and quickly and efficiently blow open the check valve.

[0084] This application embodiment obtains the correspondence between preset heating modes and preset power ranges, and after obtaining the target heating power, it can quickly determine the corresponding target heating mode according to the power range corresponding to the target heating power, effectively improving the accuracy and efficiency of intelligent control, and enabling the range hood to heat the check valve in a more suitable heating mode.

[0085] In this embodiment of the application, after obtaining the target heating power corresponding to the current oil condensation degree, the target heating power is first matched with the preset power range to determine the preset power range corresponding to the target heating power, which is the target power range. Then, according to the correspondence between the preset heating mode and the preset power range, the corresponding heating mode is determined, which is the target heating mode.

[0086] S06: Control the range hood to heat the check valve in the target heating mode, so that the check valve changes from the closed state to the open state.

[0087] In one exemplary embodiment, such as Figure 3 As shown, controlling the range hood to heat the check valve in the target heating mode, so that the check valve changes from a closed state to an open state, may include:

[0088] S061: Determine the initial heating parameters of the check valve according to the target heating mode;

[0089] S062: Control the range hood to heat the check valve with the initial heating parameters, and obtain the temperature of the check valve at a preset time; the temperature at the preset time is used to determine whether the temperature of the check valve reaches a preset temperature threshold within a preset time.

[0090] S063: If the temperature at the preset time indicates that the temperature of the check valve has not reached the preset temperature threshold within the preset time, the initial heating parameters are adjusted to obtain the adjusted heating parameters;

[0091] S064: Control the range hood to heat the check valve with the adjusted heating parameters, so that the check valve changes from the closed state to the open state.

[0092] In this embodiment, a heating module is installed on the check valve to heat the check valve and control its temperature. The heating power is adjusted based on the temperature feedback from the check valve, thereby achieving intelligent control of the check valve.

[0093] In this embodiment, after determining the target heating mode, the initial heating parameters of the check valve can be obtained based on the target heating mode. The check valve is then heated using these initial heating parameters, and its temperature is obtained. If the check valve temperature does not reach the preset temperature threshold within a preset time period, the initial heating parameters are adjusted based on the check valve temperature to obtain adjusted heating parameters. The range hood is then controlled to heat the check valve using these adjusted heating parameters. If the check valve temperature reaches the preset temperature threshold within a preset time period, no adjustment of the heating parameters is required, ensuring that the check valve can quickly change from a closed state to an open state.

[0094] This application embodiment heats the check valve and controls its temperature to adjust the heating power, thereby achieving timely regulation of the heating power and heating the check valve with a more suitable power, thus achieving precise control of the heating power of the check valve.

[0095] In one exemplary embodiment, such as Figure 4 As shown, the method may further include:

[0096] S11: Obtain the opening status information of the valve body of the check valve;

[0097] S12: When the opening status information indicates that the check valve is in the opening state, the target heating mode is determined as the current heating mode;

[0098] S13: Adjust the current heating mode to keep the oil in a melted state.

[0099] In this embodiment of the application, after heating the check valve, it is necessary to obtain the opening status information of the check valve body in real time. When the opening status information indicates that the check valve is in the open state (the check valve body has an opening action, which means that the oil has been softened, and the state of the check valve can be regarded as the open state), the aforementioned target heating mode is determined as the current heating mode, and adjustments are made according to the current heating situation to keep the oil in a melted state, thereby ensuring that the check valve remains in the open state.

[0100] This application embodiment obtains the opening status information of the check valve in real time, and can make timely adaptive adjustments according to the status of the check valve to keep the oil in a melted state and ensure that the check valve remains open, thereby improving the timeliness and accuracy of the entire intelligent control process.

[0101] In one exemplary embodiment, such as Figure 5 As shown, adjusting the current heating mode to keep the oil in a melted state may include:

[0102] S131: If the current heating mode is the first heating mode, adjust the first heating mode to the second heating mode, and control the range hood to heat the check valve in the second heating mode;

[0103] S132: If the current heating mode is the second heating mode, control the range hood to maintain the second heating mode to heat the check valve so that the oil stains remain in the melted state.

[0104] In this embodiment, if the current heating mode is the first heating mode, the first heating mode is adjusted to the second heating mode with a lower heating intensity, and the range hood is controlled to heat the check valve in the second heating mode; if the current heating mode is the second heating mode, the range hood is controlled to maintain the second heating mode to heat the check valve, so that the oil stains remain in a melted state, ensuring that the check valve is always in the open state during the operation of the range hood.

[0105] In this embodiment of the application, after determining that the check valve is in the open state, the check valve is heated in a second heating mode with a lower heating intensity. This can reduce the power consumption of operation and avoid unnecessary energy waste while keeping the oil in a melted state.

[0106] In one exemplary embodiment, such as Figure 6 As shown, the method may further include:

[0107] S21: When the range hood is detected to be started, the opening duration of the check valve in the previous operation is obtained; the opening time is the time required for the check valve to change from the closed state to the open state.

[0108] S22: Determine the preset operating time threshold of the range hood based on the attribute information of the range hood;

[0109] S23: Determine the target heating mode of the check valve based on the previous opening duration and the preset opening duration threshold.

[0110] In this embodiment, besides determining the target heating mode by the degree of oil condensation, the target heating mode can also be determined by obtaining the opening duration of the check valve during its previous operation. The opening duration is the time required for the check valve to change from a closed state to an open state. A preset opening duration threshold for the range hood is determined based on the range hood's attribute information. Since different range hood models and other attribute information vary, this application does not limit the specific range of values ​​for the preset opening duration threshold.

[0111] In this embodiment of the application, when the range hood is detected to be started, the previous opening duration of the check valve is obtained, and the target heating mode of the check valve is determined based on the previous opening duration of the check valve and the preset opening duration threshold of the range hood.

[0112] This application embodiment determines the heating mode of the check valve by comparing the previous opening duration with a preset opening duration threshold. It can adjust the intelligent control method in a timely manner according to the actual operation of the range hood, improve the adaptability with range hoods of different attributes, and achieve intelligent control of the check valve in a simpler and faster way.

[0113] In one exemplary embodiment, such as Figure 7 As shown, determining the target heating mode of the check valve based on the previous opening duration and the preset opening duration threshold may include:

[0114] S231: If the previous opening duration is less than or equal to the preset opening duration threshold, the target heating mode of the check valve is determined to be the second heating mode.

[0115] S232: If the previous opening duration is longer than the preset opening duration threshold, the target heating mode of the check valve is determined to be the first heating mode.

[0116] In this embodiment, if the previous opening time of the check valve is less than or equal to a preset opening time threshold, it indicates that there is less oil on the check valve or the oil hardness is lower, and the check valve is easier to blow open. Therefore, strong heating is not required, and the target heating mode of the check valve is determined to be the second heating mode. If the previous opening time of the check valve is greater than the preset opening time threshold, it indicates that there is more oil on the check valve or the oil hardness is higher, and the check valve is not easy to blow open. Therefore, strong heating is required to make the check valve blow open faster, and the target heating mode of the check valve is determined to be the first heating mode.

[0117] The embodiments of this application determine the target heating mode by the opening duration of the check valve the previous time, which enables the range hood to heat the check valve with a more suitable heating mode. This reduces operating power consumption and energy waste while ensuring that the check valve is blown open quickly.

[0118] In this embodiment, the heating mode can be determined solely based on the previous opening duration of the check valve, or the previous opening duration of the check valve can be combined with the degree of oil condensation, and the weight between the two can be adjusted. It can be set to prioritize the degree of oil condensation to obtain a more accurate and suitable heating power, so that the check valve can quickly change from the closed state to the open state after the range hood is started.

[0119] In one exemplary embodiment, such as Figure 8As shown, the method may further include:

[0120] S31: Obtain the first correspondence between the historical oil contamination degree and the historical heating power;

[0121] S32: Obtain the second correspondence between historical ambient temperature and historical heating power;

[0122] S33: Based on the first correspondence, determine the first weighting coefficient corresponding to the oil congealing degree, and based on the second correspondence, determine the second weighting coefficient corresponding to the ambient temperature;

[0123] S34: Determine the correspondence between heating power and the degree of oil condensation and the ambient temperature based on the first weighting coefficient and the second weighting coefficient;

[0124] S35: When the range hood is detected to be started, the current ambient temperature of the range hood and the current degree of oil condensation are obtained;

[0125] S36: Determine the target heating power based on the correspondence between the heating power, the oil congealing degree, and the ambient temperature, as well as the current ambient temperature and the current oil congealing degree.

[0126] In this embodiment, the heating power of the check valve can also be adjusted according to the ambient temperature. When the ambient temperature is low, the hardness of the oil on the check valve increases, making it more difficult to open. In this case, the heating power of the heating module on the check valve can be increased to make the oil on the check valve easier to melt. When the ambient temperature is high, the oil on the check valve will soften accordingly, making the check valve easier to open. In this case, the heating power of the heating module on the check valve can be reduced.

[0127] In this embodiment, a first correspondence between historical grease condensation and historical heating power, and a second correspondence between historical ambient temperature and historical heating power can be obtained during the historical operation of the range hood. Appropriate weighting coefficients are set to obtain the correspondence between heating power, grease condensation, and ambient temperature. When the range hood is started, the current ambient temperature and current grease condensation are obtained. Based on the correspondence between heating power, grease condensation, and ambient temperature, the final target heating power is obtained.

[0128] Wk=C1×W1+C2×W2

[0129] In the formula, Wk is the target heating power, C1 is the first weighting coefficient, C2 is the second weighting coefficient, W1 is the heating power obtained based on the oil congealing degree, and W2 is the heating power obtained based on the ambient temperature.

[0130] This application embodiment obtains the correspondence between heating power and oil condensation degree and ambient temperature, which can effectively reduce the impact of ambient temperature on the operation of the range hood, and determine the most suitable heating power according to the current operating environment of the range hood, so as to achieve more precise and efficient heating of the check valve, so that the check valve can be quickly blown open by the wind in the range hood duct.

[0131] In this embodiment, the target heating power of the check valve can also be determined independently based on the ambient temperature of the range hood. An initial relationship between ambient temperature and heating power can be established. Based on the previous opening duration of the check valve, the adjustment coefficient is adjusted sequentially. If the previous opening duration is longer than a second preset opening duration, the adjustment coefficient can be increased; if the previous opening duration is shorter than the second preset opening duration, no further increase in the adjustment coefficient is needed. This allows the adjustment coefficient corresponding to various ambient temperatures, enabling the range hood to adapt to different temperature environments and ensuring the check valve quickly reaches the opening state under appropriate heating power. For example, the target heating power can be obtained from the following formula:

[0132] Wk = A × Ws

[0133] In the formula, Wk is the target heating power, A is the adjustment coefficient, and Ws is the default heating power.

[0134] In this embodiment, the corresponding heating power can also be determined according to the ambient temperature. By obtaining the heating power corresponding to each historical ambient temperature, the correspondence between ambient temperature and heating power can be obtained. When the range hood is started, the current ambient temperature is obtained, and the corresponding heating power is determined according to the current ambient temperature. The check valve is heated in a suitable heating mode to soften the grease on the check valve, so that the check valve can be blown open by the air in the range hood duct more quickly, avoiding backflow of fumes, thereby ensuring the fume extraction effect of the range hood.

[0135] In this embodiment of the application, based on the above method, the ambient temperature and the degree of oil congealing can be further combined, the heating power obtained according to the degree of oil congealing is used as the default heating power, and the adjustment coefficient corresponding to the ambient temperature is determined to obtain the final target heating power.

[0136] In this embodiment, an initial heating power Wa can be determined based on the ambient temperature and the degree of oil congealing. Then, an adjustment coefficient A is used to adjust the initial heating power Wa according to the previous opening duration of the check valve, thus obtaining the final target heating power Wk. The specific formula is as follows:
