Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0066] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0067] The following describes an intelligent control method of a check valve of the present application. Figure 1This is a flow chart of an intelligent control method for a check valve provided in an embodiment of this specification. This specification provides method operation steps as described in the embodiment or flow chart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only order of execution. When the actual system or server product is executed, it can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment) according to the method shown in the embodiment or the accompanying drawings. Specifically, Figure 1 As shown, the method may include:

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

[0069] In an embodiment of the present application, an oil detection device can be installed in the range hood to obtain the heating power corresponding to each oil condensation degree (oil hardness) of the range hood during its historical operation. The heating power is the heating power that can melt the oil and change the check valve from a closed state to an open state.

[0070] In the embodiment of the present application, a heating module can be provided on the check valve to heat the check valve. The heating power of the heating module can be adjusted to heat the check valve at a non-powerful level, thereby softening the oil stains on the check valve and making it easier for the check valve to be quickly blown open by the wind in the range hood flue, thereby preventing the backflow of oil smoke and ensuring the use effect of the range hood.

[0071] S02: Obtaining a preset heating power database according to the correspondence between the historical oil pollution coagulation degree and the historical heating power.

[0072] In the embodiment of the present application, a preset heating power database is established based on the correspondence between the historical oil stain condensation degree and the historical heating power, which can quickly and accurately find the appropriate heating power according to the oil stain condensation degree after the range hood is started, effectively ensuring the control accuracy of the check valve heating and improving the working efficiency of the range hood.

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

[0074] S04: searching the preset heating power database for a preset heating power that matches the current oil pollution condensation degree, and obtaining a target heating power corresponding to the current oil pollution condensation degree.

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

[0076] In an exemplary embodiment, if Figure 2 As shown, the preset heating mode includes a first heating mode and a second heating mode, 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: Determine, according to the heating intensity of the first heating mode, the preset power range corresponding to the first heating mode as the first preset power range;

[0078] S052: According to the heating intensity of the second heating mode, determining 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: Obtaining the correspondence between the preset heating mode and the preset power range according to 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.

[0080] In an embodiment of the present application, the heating mode of the check valve in the range hood can be set to two levels, the first heating mode can be a strong heating mode, and the second heating mode can be an operating heating mode, wherein the heating intensity of the first heating mode is greater than the heating intensity of the second heating mode.

[0081] In an embodiment of the present application, according to the heating intensity of the first heating mode, the preset power range corresponding to the first heating mode is determined, which is the first preset power range; according to the heating intensity of the second heating mode, the preset power range corresponding to the second heating mode is determined, 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 the embodiment of the present application, after obtaining the first preset power range and the second preset power range, the corresponding relationship between the preset heating mode and the preset power range can be obtained according to the corresponding relationship between the first heating mode and the first preset power range and the corresponding relationship between the second heating mode and the second preset power range. After confirming the target power range corresponding to the target heating power, the corresponding heating mode can be determined quickly and accurately, so as to heat the check valve.

[0083] In the embodiment of the present application, in addition to the above-mentioned two heating modes, more than two heating modes can be set according to actual needs to obtain a preset power range with a more detailed range division, so that the check valve can be heated with a more suitable heating mode to blow open the check valve quickly and efficiently.

[0084] The embodiment of the present application obtains the correspondence between the preset heating mode and the preset power range. After the target heating power is obtained, the corresponding target heating mode can be quickly determined according to the power range corresponding to the target heating power, thereby effectively improving the accuracy and efficiency of intelligent control and enabling the range hood to heat the check valve with a more appropriate heating mode.

[0085] In an embodiment of the present application, after obtaining the target heating power corresponding to the current oil pollution 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, based on the correspondence between the preset heating mode and the preset power range, the corresponding heating mode is determined, that is, the target heating mode.

[0086] S06: 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.

[0087] In an exemplary embodiment, if 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: Determining initial heating parameters of the check valve according to the target heating mode;

[0089] S062: Controlling the range hood to heat the check valve with the initial heating parameter, and obtaining 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 a preset temperature threshold within the preset time, adjusting the initial heating parameter to obtain an adjusted heating parameter;

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

[0092] In an embodiment of the present application, a heating module is provided on the check valve to heat the check valve, the temperature of the check valve is controlled, and the heating power is adjusted according to the temperature feedback of the check valve, thereby realizing intelligent control of the check valve.

[0093] In the embodiment of the present application, after determining the target heating mode, the initial heating parameters of the check valve can be obtained according to the target heating mode, and the check valve is heated with the obtained initial heating parameters, and the temperature of the check valve is obtained. If the temperature of the check valve does not reach the preset temperature threshold within the preset time, the initial heating parameters are adjusted according to the temperature of the check valve to obtain the adjusted heating parameters, and the range hood is controlled to heat the check valve with the adjusted heating parameters; if the temperature of the check valve reaches the preset temperature threshold within the preset time, the heating parameters do not need to be adjusted, ensuring that the check valve can quickly change from a closed state to an open state.

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

[0095] In an exemplary embodiment, if Figure 4 As shown, the method may also include:

[0096] S11: Acquiring the opening state information of the valve body of the check valve;

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

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

[0099] In an embodiment of the present application, after the check valve is heated, 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 an open state (the opening movement of the check valve body indicates that the oil stains have been softened, and the state of the check valve can be regarded as an open state), the aforementioned target heating mode is determined as the current heating mode, and adjusted according to the current heating situation to keep the oil stains in a melted state, thereby ensuring that the check valve remains in an open state.

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

[0101] In an exemplary embodiment, if Figure 5 As shown, the adjusting of the current heating mode to keep the oil stain in a melted state may include:

[0102] S131: If the current heating mode is the first heating mode, adjusting the first heating mode to the second heating mode, and controlling 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 stain maintains the melted state.

[0104] In an embodiment of the present application, if the current heating mode is the first heating mode, the first heating mode is adjusted to the second heating mode with 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 an open state during the operation of the range hood.

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

[0106] In an exemplary embodiment, if Figure 6 As shown, the method may also include:

[0107] S21: when it is detected that the range hood is started, obtaining the last opening time of the check valve; the opening time is the time required for the check valve to change from the closed state to the open state;

[0108] S22: determining a preset activation time threshold of the range hood according to the attribute information of the range hood;

[0109] S23: Determine a target heating mode of the check valve according to the previous opening time and the preset opening time threshold.

[0110] In the embodiment of the present application, in addition to determining the target heating mode by the condensation degree of the oil stain, the target heating mode can also be determined by obtaining the opening time of the range hood check valve during the previous operation, and the opening time is the time required for the check valve to change from the closed state to the open state. According to the attribute information of the range hood, the preset opening time threshold of the range hood is determined. Since there are differences in various attribute information such as models of different range hoods, the specific value range of the preset opening time threshold is not limited in this application.

[0111] In an embodiment of the present application, when it is detected that the range hood is started, the previous opening time of the check valve is obtained, and then the target heating mode of the check valve is determined based on the previous opening time of the check valve and the preset opening time threshold of the range hood.

[0112] The embodiment of the present application determines the heating mode of the check valve by the previous opening time of the check valve and the preset opening time threshold. It can timely adjust the intelligent control method according to the actual operation of the range hood, improve the adaptability with range hoods with different properties, and realize intelligent control of the check valve in a simpler and faster way.

[0113] In an exemplary embodiment, if Figure 7 As shown, determining the target heating mode of the check valve according to the previous opening time and the preset opening time threshold may include:

[0114] S231: If the previous opening time is less than or equal to the preset opening time threshold, determining that the target heating mode of the check valve is the second heating mode;

[0115] S232: If the previous opening time is greater than the preset opening time threshold, determine that the target heating mode of the check valve is the first heating mode.

[0116] In an embodiment of the present application, if the previous opening time of the check valve is less than or equal to the 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, so there is no need for strong heating, 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, so strong heating is required to blow the check valve open faster, and the target heating mode of the check valve can be determined to be the first heating mode.

[0117] The embodiment of the present application determines the target heating mode by the previous opening time of the check valve, so that the range hood can heat the check valve with a more suitable heating mode. It can reduce operating power consumption and energy waste while ensuring that the check valve is blown open quickly.

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

[0119] In an exemplary embodiment, if Figure 8As shown, the method may also include:

[0120] S31: Obtaining a first corresponding relationship between the historical oil pollution condensation degree and the historical heating power;

[0121] S32: Acquire a second corresponding relationship between the historical ambient temperature and the historical heating power;

[0122] S33: determining a first weight coefficient corresponding to the oil pollution coagulation degree according to the first corresponding relationship, and determining a second weight coefficient corresponding to the ambient temperature according to the second corresponding relationship;

[0123] S34: determining a corresponding relationship between heating power, the oil pollution condensation degree, and the ambient temperature according to the first weight coefficient and the second weight coefficient;

[0124] S35: when it is detected that the range hood is started, obtaining the current ambient temperature of the range hood and the current condensation degree of the oil stain;

[0125] S36: Determine the target heating power according to the corresponding relationship between the heating power, the oil pollution condensation degree, the ambient temperature, the current ambient temperature, and the current oil pollution condensation degree.

[0126] In the embodiment of the present application, the heating power of the check valve can also be adjusted according to the ambient temperature. When the ambient temperature becomes low, the hardness of the oil stain on the check valve increases, making it more difficult for the check valve to be opened. At this time, the heating power of the heating module on the check valve can be increased to make the oil stain on the check valve easier to melt; when the ambient temperature becomes high, the oil stain on the check valve will become softer accordingly, making the check valve easier to open. At this time, the heating power of the heating module on the check valve can be reduced.

[0127] In the embodiment of the present application, the first correspondence between the historical oil condensation degree and the historical heating power and the second correspondence between the historical ambient temperature and the historical heating power during the historical operation of the range hood can be obtained, and a suitable weight coefficient can be set to obtain the correspondence between the heating power, the oil condensation degree, and the ambient temperature. When the range hood is started, the current ambient temperature and the current oil condensation degree are obtained, and the final target heating power is obtained according to the correspondence between the heating power, the oil condensation degree, and the ambient temperature.

[0128] Wk=C1×W1+C2×W2

[0129] Wherein, Wk is the target heating power, C1 is the first weight coefficient, C2 is the second weight coefficient, W1 is the heating power obtained according to the condensation degree of the oil pollution, and W2 is the heating power obtained according to the ambient temperature.

[0130] The embodiment of the present application can effectively reduce the impact of ambient temperature on the operation of the range hood by obtaining the corresponding relationship between the heating power and the condensation degree of oil stains and the ambient temperature, and determine the most suitable heating power according to the current operating environment of the range hood, so as to achieve more accurate and efficient heating of the check valve so that the check valve can be quickly blown open by the wind in the range hood flue.

[0131] In the embodiment of the present application, the target heating power of the check valve can also be determined based on the ambient temperature of the range hood. An initial correspondence between the ambient temperature and the heating power can be set first, and the adjustment coefficient can be adjusted successively according to the previous opening time of the check valve. If the previous opening time is longer than the second preset opening time, the adjustment coefficient can be increased. If the previous opening time is less than the second preset opening time, there is no need to continue to increase the adjustment coefficient. In this way, the adjustment coefficient corresponding to each ambient temperature can be obtained, so that the range hood can adapt to working environments of various temperatures and ensure that the check valve quickly reaches the open state under the appropriate heating power. For example, the target heating power can be obtained by the following formula:

[0132] Wk=A×Ws

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

[0134] In the embodiment of the present application, 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 corresponding relationship between the ambient temperature and the heating power is obtained. When the range hood is started, the current ambient temperature is obtained, and then 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 oil stains on the check valve, so that the check valve can be blown open more quickly by the wind in the range hood flue, avoiding the backflow of oil smoke, thereby ensuring the oil smoke absorption effect of the range hood.

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

[0136] In the embodiment of the present application, an initial heating power Wa can be determined according to the ambient temperature and the condensation degree of the oil, and then the initial heating power Wa can be adjusted by the adjustment coefficient A determined by adjusting the previous opening time of the check valve to obtain the final target heating power Wk. The specific formula can be shown as follows:

[0137] Wa=C1×W1+C2×W2

[0138] Wk=A×Wa
