[0032] The technical solution of the present application is described below through specific embodiments.

[0033] Reference Figure 1 , shows a schematic diagram of a position detection method provided by an embodiment of the present application, the method is applied to a heating-without-combustion appliance, wherein the heating-without-combustion appliance is provided with a receiving cavity and a first sensor; specifically, the method may include the following steps:

[0034] Step 101, when it is determined that there is a heating object in the accommodating cavity, obtaining first sensing information collected by the first sensor on the heating object;

[0035] The accommodating cavity can be a cylindrical cavity, which includes a first end and a second end. The first end is the opening of the accommodating cavity. The heating object can be inserted into the accommodating cavity from the opening of the accommodating cavity and inserted toward the second end along the axial direction of the accommodating cavity.

[0036] Before executing step 101, the heating without burning appliance can first identify the presence of a heating object in the accommodating cavity. If there is no heating object, there is no need to obtain the first perception information, thereby avoiding energy waste of the heating without burning appliance.

[0037] When it is determined that there is a heating object in the accommodating cavity, the first sensor located inside the heating non-combustion appliance is called. The first sensor has a corresponding sensing range, and the accommodating cavity is located within its sensing range. Therefore, first sensing information collected for the part of the heating object located in the accommodating cavity can be obtained.

[0038] The heating object is provided with an aerosol matrix for being placed in the containing cavity. The aerosol matrix can be heated to a certain temperature by the heating without burning device to release the aerosol, and the aerosol can be inhaled once or multiple times. The heating without burning device can periodically or continuously heat the aerosol matrix so that the aerosol matrix releases the aerosol multiple times.

[0039] Step 102, determining a first angle value of a portion of the heating object located in the accommodating cavity relative to a position of the first sensor according to the first sensing information;

[0040] The portion of the heating object located in the accommodating cavity refers to the portion of the heating object from the opening of the accommodating cavity to the edge of the heating object.

[0041] Since part of the heating object has been inserted into the accommodating cavity at this time, this part is also located in the sensing area of ​​the first sensor.

[0042] As an example, a gap is provided in the axial direction of the accommodation cavity, and the first sensor can emit a light signal, and receive the light signal reflected by the accommodation cavity and / or the light signal reflected by the heated object after passing through the gap, and generate first perception information based on the reflected light signal. The first sensor can distinguish the light signal reflected by the accommodation cavity from the light signal reflected by the heated object, and thus can determine the first angle value based on the first perception information and the position of the first sensor. Specifically, the first angle value is the angle formed by the two ends of the portion of the heated object located in the accommodation cavity and the line segment where the first sensor is located.

[0043] Reference Figure 2 , shows a schematic diagram of a receiving cavity and a first sensor provided in an embodiment of the present application, such as Figure 2As shown, the first angle of the portion of the heating object located in the accommodating cavity relative to the position of the first sensor is angle δ. According to the first sensing information, the angle values ​​of angle α and angle β can be determined, and then the first value, that is, the angle value of angle δ can be determined.

[0044] Step 103: determining the real-time position of the heating object in the accommodating cavity according to the first angle value.

[0045] As an example, the real-time position is the position of the edge of the heating object in the axial direction of the receiving cavity. Since the first angle value changes with the change in the length of the portion of the heating object that has been inserted into the receiving cavity, the embodiment of the present application can determine the change in the length of the portion of the heating object that has been inserted into the receiving cavity based on the change in the first angle value, thereby detecting the real-time position of the heating object in the receiving cavity.

[0046] As another example, the real-time position is a position state, which is at the target position or not at the target position. Whether the heating object is at the target position is determined according to the first angle value, thereby determining the real-time position of the heating object.

[0047] In an embodiment of the present application, when it is determined that there is a heating object in the accommodating cavity, first perception information collected by the first sensor for the heating object is obtained; the heating object is provided with an aerosol matrix for being placed in the accommodating cavity; based on the first perception information, a first angle value of the part of the heating object located in the accommodating cavity relative to the position of the first sensor is determined; and the real-time position of the heating object in the accommodating cavity is determined based on the first angle value, so that when a user inserts the heating object into the heating without burning appliance, the heating without burning appliance can automatically identify the real-time position of the heating object in the accommodating cavity based on the angle information corresponding to the heating object without manual confirmation.

[0048] In some implementations of the embodiments of the present application, the method further includes: in response to the real-time position of the heating object being a preset target position, starting to heat the heating object.

[0049] After determining the real-time position of the heating object, the heating-not-burning appliance continuously identifies whether the real-time position of the heating object is the target position. When the heating object is at the target position, it is confirmed that the heating object is fully inserted into the accommodating cavity. As an example, the target position is the position of the second end, and when the heating object reaches the target position, the heating object is in contact with the second end. As another example, when the heating object reaches the target position, the heating object is a preset distance away from the second end.

[0050] The real-time position can be represented by the distance between the edge of the heating object and the preset target position in the accommodating cavity. For example, if the real-time position is 3 cm, the position of the heating object is 3 cm away from the target position.

[0051] The target position is the position where the heating object is inserted into the accommodating cavity to the maximum insertion depth. For example, if the target position is the bottom of the accommodating cavity, the real-time position is represented by the distance between the heating object and the bottom of the accommodating cavity, that is, the remaining insertion distance of the heating object.

[0052] When the real-time position is 0, the position of the heating object is determined to be the target position. The heating-not-burning device can automatically start heating the heating object when the real-time position of the heating object is determined to be the target position, thereby increasing the temperature of the aerosol matrix in the heating object, and releasing the aerosol when the aerosol matrix reaches a certain temperature.

[0053] The heating object is also provided with a component of a non-aerosol matrix, such as a nozzle. When the aerosol matrix releases aerosol, the user can inhale the aerosol through the nozzle. When the heating object reaches the target position, the component of the non-aerosol matrix is ​​at least partially located outside the accommodation cavity to avoid affecting the user's inhalation of the aerosol.

[0054] Through the embodiments of the present application, not only can the real-time position of the heating object in the accommodating cavity be detected, but also the heating object can be automatically started to be heated when the real-time position of the heating object is the target position. Without setting a delayed trigger heating, the heating of the heating object can be automatically triggered, so that the heating object is heated and baked when it is fully inserted into the accommodating cavity, thereby reducing the situation where the aerosol matrix cannot be released or reduces the release of aerosol due to incomplete heating, and further improving the user experience of obtaining aerosols using heat-not-burn appliances.

[0055] In one implementation of the embodiment of the present application, the length of the heating object inserted into the accommodating cavity can be determined based on the first angle value, and the real-time position of the heating object can be determined based on the length. Specifically, step 103 may include: determining the first length value of the heating object in the accommodating cavity based on the first angle value and the preset characteristic parameters; determining the second length value; the second length value is determined by the second angle value and the first preset distance; the second angle value is the angle formed by the opening of the accommodating cavity and the preset target position relative to the position of the first sensor; and determining the real-time position of the heating object in the accommodating cavity based on the difference between the first length value and the second length value.

[0056] The characteristic parameters include parameters related to calculating the first length value and can be determined in advance, such as Figure 2As shown, the characteristic parameters may include one or more of the angle value of angle α, the angle value of angle γ, the length value of the first preset distance, and the internal length D2 of the accommodating cavity. The first preset distance is the shortest distance between the first sensor and the accommodating cavity, such as Figure 2 As shown, the first preset distance can be the length of the dotted line L. The first length value can be determined by combining the first angle value and the characteristic parameter with the corresponding trigonometric function calculation formula. The first length value is the length of the portion of the heating object located in the accommodating cavity (i.e., the delay length of the heating object in the accommodating cavity). Figure 2 As shown, the first length value is D1.

[0057] Since the positions of the first sensor and the accommodating cavity are fixed, the characteristic parameters can be predetermined before the execution of the embodiment of the present application. In order to improve the calculation accuracy, the characteristic parameters can also be determined based on the first perception information. It is only necessary to determine the characteristic parameters before calculating the first length value.

[0058] The second length value is the internal length of the accommodation cavity, and the second length value can be determined by reading a preset characteristic parameter, or can be calculated based on the second angle value and the first preset distance. As shown in Figure 2, the second angle value is the sum of α and γ.

[0059] After the first length value and the second length value are obtained, the real-time position of the heating object is determined according to the difference between the first length value and the second length value.

[0060] For the above example where the real-time position is the position of the edge of the heating object in the axial direction of the accommodation cavity, the real-time position is the difference between the second length value and the first length value. Figure 2 For example, the real-time position is the difference between D2 and D1.

[0061] For the above example where the real-time position is a position state, the magnitude relationship between the first length value and the second length value can be determined. If the first length is less than the second length, the real-time position is determined to be a position state that is not at the target position. As the heated object moves toward the target position, the first length gradually increases. If the first length value is not less than the second length value, the real-time position is determined to be a position state that is at the target position. Similarly, if the ratio of the first length value to the second length value is 1, the real-time position is a position state that is not at the target position; if the ratio of the first length value to the second length value is 1, the real-time position is a position state that is at the target position.

[0062] In one implementation of the embodiment of the present application, the real-time position of the heating object can be determined based on the first angle value and the second angle value corresponding to the target position. Specifically, step 103 may include: determining the second angle value; the second angle value is the angle formed by the opening of the accommodating cavity and the preset target position relative to the position of the first sensor; if the first angle value is not less than the second angle value, it is determined that the first angle value meets the preset judgment condition; if the first angle value is less than the second angle value, it is determined that the first angle value does not meet the preset judgment condition.

[0063] As described above, the second angle value is the sum of the angle value of angle α and the angle value of angle γ. The second angle value can be determined in advance or calculated in real time based on the first perception information.

[0064] For the above example where the real-time position is the position of the edge of the heating object in the axial direction of the accommodation cavity, the length in the axial direction of the accommodation cavity corresponding to the second angle value, i.e., the above second length value, can be determined first. The product value of the ratio of the first angle value to the second angle value and the second length value is determined, and the difference between the second length value and the product value is determined as the real-time position of the heating object.

[0065] For the above-mentioned example in which the real-time position is a position state, the magnitude relationship between the first angle value and the second angle value can be determined. If the first angle value is less than the second angle value, the real-time position is determined to be a position state that is not at the target position;. As the heating object moves toward the target position, the first angle value gradually increases. If the first angle value increases to be not less than the second angle value, the real-time position is determined to be a position state that is at the target position. Similarly, if the ratio of the first angle value to the second angle value is not 1, the real-time position is a position state that is not at the target position; if the ratio of the first angle value to the second angle value is 1, the real-time position is a position state that is at the target position.

[0066] In some implementations of the embodiments of the present application, the first sensor is an infrared sensor or an electromagnetic sensor.

[0067] The first sensor may be an infrared sensor, and the optical signal may be infrared light.

[0068] The first sensor may be an electromagnetic sensor, and a magnetic field may be set in the heating-not-burning appliance, and the first sensing information may be magnetic flux information. If there is a heating object in the accommodating cavity, the magnetic flux of the area where the heating object is present is different from that of the area where the heating object is not present in the accommodating cavity, so the position reached by the heating object can be determined by the magnetic flux, thereby obtaining the angle values ​​of angle α, angle β, and angle γ, and then obtaining the first angle value as the size of angle δ and the second angle value (the second angle value is the sum of the angle values ​​of angle α and angle γ), and further, determining whether the first angle value meets the preset determination condition.

[0069] In some implementations of the embodiments of the present application, before step 101, the method further includes: obtaining second perception information of the opening of the accommodating cavity sensed by a preset second sensor; and determining that the heating object exists in the accommodating cavity when the second perception information satisfies a preset intensity range.

[0070] The opening of the accommodating cavity is located within the sensing area of ​​the second sensor, and the second sensor can obtain second sensing information for the location of the opening. The preset intensity range can be that the intensity value of the second sensing information meets the preset intensity range.

[0071] Before the implementation of the embodiment of the present application, the intensity value of the second perception information of the second sensor can be collected when objects of different materials are at the opening position, and then the intensity value of one or more heating objects can be determined. The above intensity range is determined by the intensity values ​​of various heating objects, and then it can be realized that when there is an object at the opening of the accommodating cavity, whether the object is a heating object. When it is determined that the intensity value of the second perception information is within the above intensity range, it is determined that there is a heating object in the accommodating cavity, and the first sensor is called to obtain the first perception information. When it is determined that the intensity value of the second perception information is not within the above intensity range, the first sensor is not called to obtain the first perception information, and then the heating function of the heating non-combustion appliance will not be turned on to avoid heating non-heating objects.

[0072] In the embodiment of the present application, a second sensor is used to identify whether the object entering the accommodating cavity is a heating object, thereby avoiding the heating function of the heating non-combustion appliance being mistakenly turned on when an object other than the heating object enters the accommodating cavity, thereby avoiding the risks that may be caused by heating the non-heating object.

[0073] As an example, when the heating without burning appliance is in a sleep state, the second sensing information is obtained at a certain periodic frequency (0.5 seconds to 2 seconds / time) to periodically determine whether there is a heating object in the accommodating cavity.

[0074] In some implementations of the embodiments of the present application, after starting to heat the heating object in response to the heating object reaching the target position, the method further includes: obtaining second perception information of a preset second sensor sensing the opening of the accommodating cavity; and stopping heating the heating object if the second perception information does not meet a preset intensity range.

[0075] After the heating object begins to be heated, the second perception information is still obtained at a certain frequency. If the second perception information does not meet the preset intensity range, it means that the heating object has been pulled out of the containing cavity. Therefore, the heating of the object is automatically stopped to prevent the heating non-combustion appliance from wasting resources and preventing the heating non-combustion appliance from being damaged by "empty burning".

[0076] It should be noted that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0077] Reference Figure 3 , shows a flow chart of automatic heating control of a heating-without-combustion appliance provided in an embodiment of the present application, comprising the following steps:

[0078] Step 301: The appliance (heating but not burning appliance) is in a dormant state, and the second sensor is called at a period T1.

[0079] Step 302: The second sensor receives the intensity of reflected infrared light.

[0080] Step 303, determine whether the infrared light intensity is within a preset intensity range. If yes, it is determined that a heating object is inserted into the receiving cavity, and steps 304-306 are executed; if no, it is determined that no object is inserted into the receiving cavity or the object inserted into the receiving cavity is not a heating object, and return to step 301.

[0081] Step 304 , the first sensor of the awakening device is called with a period T2 .

[0082] Step 305: The first sensor returns first perception information each time it is called.

[0083] Step 306: Calculate a first length value according to the first perception information and the length calculation function.

[0084] Step 307, whether the first length value is less than the second length value. If the first length value is not less than the second length value, it is determined that the heating object is fully inserted into the accommodating cavity and the heating object reaches the target position, and step 308 is executed; if the first length value is less than the second length value, it is determined that the heating object is not fully inserted into the accommodating cavity and the heating object does not reach the target position, and the process returns to step 305.

[0085] Step 308, start the heating module to start heating the heating object. Set the heating flag bit to 1 to start the heating module.

[0086] Step 309: If the infrared light intensity received by the second sensor is not within the preset range, the heating module stops working. The heating flag is set to 0, so that the heating module stops working and enters a dormant state after 5 seconds, and returns to step 301.
