[0026] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0027] The present invention provides a pressure data acquisition device. Figure 1 and Figure 2 The pressure data acquisition device is used to collect the pressure data of the knob. The knob includes a knob seat 23 and a knob cover 21 covered on the knob seat 23. The pressure data acquisition device includes: a pressure sensor 11, an analog-to-digital converter 12, and a processor 13; the pressure sensor 11 is arranged in a receiving cavity surrounded by the knob seat 23 and the knob cover 21. The pressure sensor 11 is electrically connected to the analog-to-digital converter 12, and the analog-to-digital converter 12 is electrically connected to the processor 13.

[0028] The pressure sensor 11 can be connected to the analog-to-digital converter 12 via a connecting wire or wirelessly. The specific connection method between the pressure sensor 11 and the analog-to-digital converter 12 can be set according to actual conditions and is not particularly limited here.

[0029] The data collected by the pressure sensor 11 includes at least one set of pressure data and the collection time corresponding to the pressure data. The pressure sensor 11 transmits the collected pressure data to the analog-to-digital converter 12, which converts the pressure data into a digital signal and monitors the converted digital signal. The analog-to-digital converter 12 can be connected to the processor 13 by a connecting line or by a wireless connection. The analog-to-digital converter 12 sends the converted digital signal to the processor 13, which processes it. The processor 13 uses data debugging software to save the pressure data, process the data, and perform digital-to-digital analysis and conversion.

[0030] Specifically, the processor 13 splits each group of effective pressure data from the collected pressure data according to the data distribution law. It should be noted that the data distribution law is that if the pressure value of the pressure data satisfies the order from small to large, and then from large to small, and the pressure value is 0 when no pressure test is performed, then the pressure data is effective pressure data. After completing the splitting of the effective pressure data, the processor 13 extracts key data from each group of effective pressure data, analyzes the performance of the valve body to be tested according to the key data and the pressure test phenomenon corresponding to the key data, and thus determines the association between the phenomenon and the key data.

[0031] The pressure data may include pressure values ​​at different times. The key data may include the maximum pressure, the start time of the pressure, the time of the maximum pressure, and the end time of the pressure.

[0032] Taking the stove valve body as an example, after extracting key data from each set of valid pressure data, the processor 13 calculates the pressure maintenance time by the pressure start time and the pressure end time in combination with the phenomenon of whether the ignition is successful, and determines the relationship between the ignition success rate and the pressure value, the relationship between the ignition success rate and the pressure maintenance time, and the user's usage habits. The user's usage habits may include the pressure value and the pressure maintenance time.

[0033] It should be noted that the valve stem 31 of the valve body to be tested passes through the valve stem hole of the knob seat 23, and the pressure sensor collects the pressure of the knob, which actually collects the pressure of the valve stem 31 of the valve body to be tested.

[0034] In this embodiment, by arranging a pressure data acquisition device on the valve body to be tested, the pressure of a single valve body and a complete valve body can be tested, and the actual usage scenario of the user can be truly simulated. A pressure test can be performed during the use of the valve body to be tested, so that the stability and reliability of the valve body to be tested can be analyzed based on the pressure data. The structure is simple and the cost is low.

[0035] In one embodiment, the pressure data acquisition device includes: a display. The display is electrically connected to the analog-to-digital converter 12 .

[0036] The display is used to receive the digital signal sent by the analog-to-digital converter 12 and display the digital signal representing the pressure data in real time.

[0037] In this embodiment, a display is provided and electrically connected to the analog-to-digital converter 12 to realize real-time display of digital signals, so that the user can intuitively monitor the pressure data and analyze the stability and reliability of the valve body to be tested based on the pressure data.

[0038] In one embodiment, the display is electrically connected to the processor 13. The display is used to receive the analysis result of the processor 13 and display the analysis result in real time.

[0039] In this embodiment, a display is provided and electrically connected to the processor 13 to realize real-time display of the pressure data analysis results, so that the user can intuitively monitor the pressure data and perform stability and reliability analysis of the valve body to be tested based on the pressure data.

[0040] In one embodiment, the knob further comprises: a valve stem 31 penetrating the knob seat 23. The action point of the pressure sensor 11 is used to contact the valve stem 31.

[0041] It should be noted that the valve stem 31 is the valve stem 31 of the valve body to be tested. The valve stem 31 passes through the knob seat 23 through the valve stem hole at the center of the knob. Taking the gas stove as an example, when the user ignites, he needs to press the knob downward, and the action point of the pressure sensor 11 directly contacts and interacts with the valve stem 31, thereby measuring the pressure value of the valve body during the ignition process, rather than the force on the knob.

[0042] In this embodiment, by making the action point of the pressure sensor 11 contact the valve stem 31, the pressure of the valve body to be tested is directly measured. Compared with measuring the force of the knob, the reliability and stability of the valve body to be tested are more accurately characterized, making the analysis of pressure data more accurate and reliable.

[0043] In one embodiment, the knob further comprises: a heat insulation layer. The heat insulation layer is arranged on the surface of the knob.

[0044] Specifically, the heat insulation layer is a heat insulation material sprayed on the surface of the knob. It is understandable that if the knob is located on the stove, the user needs to touch the knob to control the flame of the stove during the use of the stove. In order to avoid burns to the user and to avoid failure of the pressure sensor 11 disposed in the accommodating cavity of the knob due to high temperature, a heat insulation layer needs to be provided on the surface of the knob. When the stove is in use, the stove eye will generate a flame, and the heat of the flame will radiate to the surroundings, resulting in a high temperature on the surface of the knob. Spraying heat insulation material on the surface of the knob blocks the heat, so that the heat of the flame cannot be transferred to the pressure sensor 11 in the accommodating cavity of the knob.

[0045] In this embodiment, by spraying heat insulating material on the surface of the knob, the pressure sensor 11 arranged in the accommodating cavity of the knob is prevented from malfunctioning due to high temperature, thereby improving the high temperature resistance of the knob, preventing the user from being burned when touching the knob, and realizing the protection function for the user.

[0046] In one embodiment, the heat insulating layer is disposed inside the knob.

[0047] Specifically, the heat insulation layer is the heat insulation cotton filled inside the knob. The heat insulation cotton has the characteristics of high temperature resistance, non-flammability, low thermal conductivity, etc. Filling the heat insulation cotton inside the knob can block the heat when the stove is used, and avoid the pressure sensor 11 in the knob's accommodating cavity from malfunctioning due to high temperature.

[0048] In this embodiment, by filling the inside of the knob with heat insulation cotton, the pressure sensor 11 arranged in the accommodating cavity of the knob is prevented from malfunctioning due to high temperature, the accuracy of the pressure data collected by the pressure sensor 11 is ensured, and the high temperature resistance of the knob is improved.

[0049] The utility model also provides a cooking appliance, see Figure 3 , the cooker comprises: the pressure data acquisition device in any one of the above embodiments.

[0050] Specifically, the processor 13 splits each group of valid pressure data from the collected pressure data according to the data distribution law. It should be noted that the data distribution law is that if the pressure value of the pressure data satisfies the order from small to large, and then from large to small, and the pressure value is 0 when no pressure test is performed, then the pressure data is valid pressure data. After completing the splitting of the valid pressure data, the processor 13 extracts key data from each group of valid pressure data, and performs a system analysis based on the key data and the pressure test phenomenon corresponding to the key data, so as to determine the association between the phenomenon and the key data.

[0051] Among them, the pressure test for the stove valve body can be pressing the knob in a static state, that is, only pressing the knob without performing an ignition operation. The pressure test for the stove valve body can also be an ignition test, which is used to simulate the actual working scene of the stove, collect pressure data of different users when performing ignition operations and analyze them. When the knob is pressed, the knob is subjected to downward pressure, and the pressure sensor 11 collects the pressure of the valve body. The pressure test phenomenon is whether the ignition is successful. The association between the phenomenon and the key data includes the relationship between the ignition success rate and the pressure value, the relationship between the ignition success rate and the pressure maintenance time, and the user's usage habits. The user's usage habits may include the pressure value and the pressure maintenance time. Since the stove knob is generally round, a circular pressure sensor 11 can be used in the pressure data acquisition device.

[0052] See also Figure 4 The valve stem 31 of the stove valve body passes through the knob seat 23 through the valve stem hole of the knob seat 23 , and the pressure sensor actually collects the pressure of the valve stem 31 of the stove valve body.

[0053] In this embodiment, a pressure data acquisition device is used without changing the shape of the knob and the depth of the valve stem hole, ensuring that the user can keep consistent with the actual working scene of the stove when igniting, thereby reducing the error of the pressure test and providing strong data support for improving the performance and reliability of the stove.

[0054] In one embodiment, the knob cover 21 and the knob seat 23 are detachably connected, so that an ideal knob size and shape can be constructed according to actual needs, thereby improving the practicality of the knob and facilitating pressure testing by simulating the working scenario of the valve body to be tested, so that the pressure test results are closer to the pressure value in the actual usage scenario.

[0055] In one embodiment, the shape of the knob includes at least one of the following: circle, rectangle, square, triangle, ellipse.

[0056] In practical applications, the shape of the knob can be selected according to the usage scenario of the valve body to be tested and the shape of the valve body to be tested. For example, if the valve body to be tested is a valve body for stove ignition, the valve body needs to withstand downward pressure and rotational torque, and a round knob is generally used to better simulate the stove ignition scenario for pressure testing.

[0057] In this embodiment, the knob shape can be a variety of different shapes with strong applicability. A matching knob can be selected according to the actual usage scenario, so as to better simulate the working scenario of the valve body to be tested for pressure testing, so that the pressure test results are closer to the pressure value in the actual usage scenario, thereby improving the accuracy of the pressure test and providing strong data support for improving the performance and reliability of the stove.

[0058] In one embodiment, the cooker includes at least two knobs, and each knob is provided with at least one pressure sensor 11 .

[0059] The number of pressure sensors 11 provided for each knob can be determined according to actual conditions. It is understandable that if the number of pressure sensors 11 is greater, the pressure data collected by multiple pressure sensors 11 can be analyzed to improve the accuracy of the pressure data, while avoiding the problem of inability to accurately collect pressure data due to a failure of one pressure sensor 11. However, too many pressure sensors 11 will increase the manufacturing cost of the knob, so the appropriate number of pressure sensors 11 can be selected according to actual conditions.

[0060] In this embodiment, at least one pressure sensor 11 is provided on each knob. Pressure sensors 11 are added according to actual conditions. The structure is simple and the cost is low. Pressure tests are performed on each knob to improve the accuracy of pressure data, which facilitates reliability analysis of the stove based on the pressure data and provides a theoretical basis for improving the stability and reliability of the stove.

[0061] In one embodiment, the stove comprises: a heat insulation board. The heat insulation board can be placed upright on the stove table and the heat insulation board is located between the stove eye and the knob of the stove.

[0062] During the use of the stove, the heat generated by the stove eye will be transferred to the knob of the stove, causing the knob to become seriously hot and the user cannot operate the knob normally. In addition, the components contained in the knob will be damaged due to the high temperature and cannot be used normally. If the pressure sensor 11 in the knob is damaged, the collected pressure data cannot be used as a basis for analyzing the reliability of the stove valve body.

[0063] It should be noted that the heat insulation board can be in various shapes, such as round, rectangular, square, triangular, and elliptical. The function of the heat insulation board is to provide heat insulation.

[0064] In this embodiment, the heat insulation board has a simple structure, is easy to manufacture and has low cost. When in use, the user can place it on the stove table according to specific conditions, and it is ready to use, which is convenient to use. The heat insulation board is used to prevent the components contained in the knob from being damaged due to excessive temperature, thereby improving the high temperature resistance of the knob.

[0065] In one embodiment, the cooker comprises: a first waterproof ring. The first waterproof ring is embedded in the valve stem hole of the knob.

[0066] It is understandable that if water flows into the stove valve body, it will cause rust or poor circuit contact, reducing the ignition success rate, so it is necessary to set a first waterproof ring. The first waterproof ring is embedded in the valve stem hole of the knob to prevent water from entering the valve body through the valve stem hole.

[0067] In this embodiment, a first waterproof ring is embedded in the valve stem hole of the knob to prevent water from entering the valve body through the valve stem hole and causing the valve body to rust. This protects the components in the stove, improves the service life and performance of the stove, and increases the ignition success rate.

[0068] In one embodiment, the cooker includes: a second waterproof ring. The second waterproof ring is nested on the valve stem 31. The second waterproof ring is nested on the valve stem 31 to prevent water from entering the valve body through the valve stem 31.

[0069] In this embodiment, by embedding the second waterproof ring on the valve stem 31, water is prevented from entering the valve body through the valve stem 31, thereby protecting the stove valve body, improving the service life and performance of the stove, and preventing the stove valve body from being damaged.

[0070] In one embodiment, the cooker includes: a first waterproof ring and a second waterproof ring.

[0071] In this embodiment, by providing the first waterproof ring and the second waterproof ring, water on the stove table can be better prevented from flowing into the stove valve body, thereby protecting the components in the stove and improving the service life and performance of the stove.

[0072] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
