The airflow channel is used for introducing external airflow into the atomization medium. A temperature sensor is arranged in the airflow channel. The temperature sensor is connected with a heating structure used for heating the temperature sensor. The temperature sensor and the heating structure are both in communication connection with a control panel. The heating structure heats the temperature sensor while the heating cavity starts to heat the atomization medium.

[0002] To improve the user's suction experience, heated tobacco products typically incorporate technology that calculates the number of suction ports. This number is used to balance temperature control and suction time, thereby improving suction consistency and enhancing the user experience. Traditional heated tobacco products suffer from low accuracy in detecting the number of suction ports, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this application is to provide a heating non-combustible appliance to solve the technical problem of low detection accuracy of the number of suction ports in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a heated non-combustible appliance is provided, having an airflow channel and a heating chamber. The heating chamber is used to contain and heat an atomizing medium. The airflow channel is used to introduce external airflow into the atomizing medium. A temperature sensor is provided in the airflow channel. The temperature sensor is connected to a heating structure for heating the temperature sensor. Both the temperature sensor and the heating structure are communicatively connected to a control board. While the heating chamber starts heating the atomizing medium, the heating structure heats the temperature sensor.

[0005] In some embodiments, the heated non-combustible appliance further includes a heating element assembly, the heating cavity being formed in the heating element assembly, and the heating element assembly including the heating structure.

[0006] In some embodiments, the heated non-combustible appliance further includes a heat-conducting element connected between the heating element assembly and the temperature sensor.

[0007] In some embodiments, the heated non-combustible appliance further includes a heat insulation element, which is sleeved outside the heating element assembly, and the airflow channel is located on the outside of the heat insulation element.

[0008] In some embodiments, the temperature sensor is attached to the outside of the thermal insulation component;

[0009] Alternatively, the heat insulation component may have a through slot, through which the heat-conducting component passes to connect the heating element assembly and the temperature sensor.

[0010] In some embodiments, the heated non-combustible appliance further includes a housing assembly sleeved outside the heat insulation member, the airflow channel being formed in the housing assembly, the sidewall of the housing assembly having a mounting groove, the heat-conducting member abutting against the side of the housing assembly facing the heat insulation member and sealing the end face of the mounting groove, and the temperature sensor being attached to the heat-conducting member via the mounting groove.

[0011] In some embodiments, the housing assembly includes an inner shell, a sealing sheet, and an outer shell. The inner shell is fitted over the heat insulation member, and the outer shell is fitted over the inner shell. An airflow channel is formed on the outer peripheral surface of the inner shell. The sealing sheet covers the port of the airflow channel facing the outer shell, and a first air inlet communicating with the airflow channel is provided between the sealing sheet and the inner shell.

[0012] In some embodiments, the heated non-combustible appliance further includes a first connecting seat, the first connecting seat having an installation cavity and a connecting cavity, the installation cavity being used to install the distal lip end of the atomizing medium and communicating with the atomizing medium, and the connecting cavity being communicating with the airflow channel.

[0013] In some embodiments, the heating element assembly includes a housing structure for accommodating the atomizing medium and a heating film attached to the outer surface of the housing structure. The heating film includes a first heating segment and a second heating segment. When the heating film is energized, the first heating segment heats up before the second heating segment, and the distance from the temperature sensor to the first heating segment is less than the distance from the temperature sensor to the second heating segment.

[0014] In some embodiments, the heated non-combustible appliance includes a heating element assembly and a heating device, the heating cavity being formed in the heating element assembly, and the heating device including the heating structure.

[0015] The beneficial effects of the heated non-combustible appliance provided in this application are as follows: By setting a temperature sensor in the airflow channel and connecting the temperature sensor to a heating structure, when the heated non-combustible appliance starts heating the atomizing medium, the heating structure also starts heating, raising the temperature of the temperature sensor so that the temperature sensor detects a relatively high first temperature and feeds it back to the control board; when the user inhales, external airflow enters the airflow channel, and the temperature sensor detects a relatively low second temperature of the external airflow and feeds it back to the control board. Because the temperature difference between the heating structure and the external airflow is large, the temperature difference between the first temperature and the second temperature is greater than the preset threshold in the control board, resulting in the calculation of the number of inhalations. This enables the calculation of the number of inhalations, thereby improving the recognition rate of the number of temperature changes and improving the detection accuracy of the number of inhalations.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0027] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0028] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] Traditional heated non-combustible appliances typically use airflow sensors, pressure sensors, or silicon microphones to identify the number of suction ports by detecting changes in airflow or pressure. This technology is highly susceptible to contamination from condensate or foreign matter, and is prone to failure and misjudgment.

[0031] To address this, the inventors of this application proposed using a temperature sensor to detect temperature changes in the airflow channel and determining the number of suction ports based on the number of temperature changes in the airflow channel. However, in the initial stage of heating the non-combustible appliance, the temperature of the airflow channel is not significantly different from the outside air temperature. When the user performs suction, the airflow passes over the surface of the temperature sensor without generating a temperature difference, or the temperature difference is very small. This temperature difference is insufficient to trigger the preset threshold for temperature changes and thus affect the number of suction ports count, resulting in a low recognition rate of the number of temperature changes and ultimately affecting the accuracy of suction port count detection.

[0032] To address the aforementioned issues, this application provides a heated non-combustible appliance. By connecting a temperature sensor 500 to a heating structure, the heating structure heats the temperature sensor 500, enabling it to acquire a higher temperature during the initial heating phase of the appliance. This allows the temperature sensor 500 to detect a significant temperature difference when the user inhales, sufficient to trigger a preset threshold for temperature change and thus calculate the number of inhalations. This improves the recognition rate of temperature changes and enhances the accuracy of inhalation detection.

[0033] Please see Figures 1 to 3 The heated non-combustible appliance provided in the embodiments of this application will now be described. This heated non-combustible appliance is used to heat the atomizing medium 5 to produce an aerosol that can be inhaled by a smoker.

[0034] The heated non-combustible appliance has an airflow channel 140 and a heating chamber 230. The heating chamber 230 is used to contain and heat the atomizing medium 5. The airflow channel 140 is used to introduce external airflow into the atomizing medium 5. A temperature sensor 500 is provided in the airflow channel 140. The temperature sensor 500 is connected to a heating structure for heating the temperature sensor 500. Both the temperature sensor 500 and the heating structure are communicatively connected to a control board (not shown). When the heating chamber 230 starts heating the atomizing medium 5, the heating structure heats the temperature sensor 500.

[0035] When the heated non-combustible appliance is activated, the atomizing medium 5, located in the heating chamber 230, is heated and does not burn, thus generating an aerosol. When the user inhales the heated non-combustible appliance, external airflow enters the atomizing medium 5 through the airflow channel 140 to carry the aerosol generated by the atomizing medium 5 out for the user to inhale.

[0036] Since the temperature sensor 500 is connected to the heating structure, when the heated non-combustible appliance starts heating, the heating structure also starts heating, raising the temperature of the temperature sensor 500 so that the temperature sensor 500 detects a relatively high first temperature T1 and feeds it back to the control board. When the user inhales, external airflow enters the airflow channel 140, and the temperature sensor 500 detects a relatively low second temperature T2 of the external airflow and feeds it back to the control board. Because the temperature difference between the heating structure and the external airflow is large, the temperature difference ΔT between the first temperature T1 and the second temperature T2 is greater than the preset threshold in the control board, resulting in the calculation of the number of inhalations. When the user inhales again, the external airflow enters the airflow channel 140 again, the temperature sensor 500 detects the temperature difference again, and the control board calculates the number of inhalations again. This process is repeated to achieve the counting of the number of inhalations with high accuracy, thereby improving the detection accuracy of the number of inhalations. This allows for temperature control based on the number of suction ports and helps determine the usage status of the atomizing medium 5. When the atomizing medium 5 has finished baking, the user is reminded to replace it with a new one.

[0037] Optionally, the temperature sensor 500 can be a thermistor temperature sensor 500, a resistance temperature sensor 500, a thermocouple temperature sensor 500, etc., as long as it can detect the temperature of the heating structure and the temperature of the airflow and feed it back to the control board.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The heated non-combustible appliance includes a heating element assembly 200, a heating chamber 230 formed in the heating element assembly 200, and a heating structure. In this embodiment, the temperature sensor 500 is directly connected to the heating element assembly 200 used to heat the atomizing medium 5. The heating element assembly 200 heats the temperature sensor 500, enabling it to detect a higher temperature even in the initial heating stage. This not only improves the accuracy of the number of suction ports but also eliminates the need for an additional heating structure, simplifying the structure and reducing the cost of the entire heated non-combustible appliance.

[0039] In some embodiments, please refer to Figure 2 and Figure 3The heated non-combustible appliance also includes a heat-conducting element 400, which is connected between the heating element assembly 200 and the temperature sensor 500. The heat-conducting element 400 allows for rapid transfer of heat generated by the heating element assembly 200 to the temperature sensor 500, ensuring that the temperature sensor 500 has a high initial temperature T1 during the initial heating phase of the heated non-combustible appliance. This improves the accuracy of the appliance's detection of the number of suction ports. Understandably, in other embodiments of this application, where structurally permissible, the temperature sensor 500 may also be directly connected to the heating element assembly 200.

[0040] Preferably, the heat-conducting element 400 includes a heat-conducting copper sheet, which can be directly attached to the outer surface of the heating element assembly 200 or indirectly (separated by other structures, such as other conductive structures or the heat insulation element 300 mentioned later) attached to the outer surface of the heating element assembly 200. The temperature sensor 500 is attached to the heat-conducting copper sheet. Specifically, the heat-conducting copper sheet can be annular and attached to the outer surface of the heating element assembly 200, or it can be in block shape, as long as the size of the heat-conducting copper sheet is designed to accommodate the temperature sensor 500. It is understood that in other embodiments of this application, the heat-conducting element 400 can also be made of other materials, such as aluminum sheet, iron sheet, titanium sheet, or magnesium sheet.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 The heated non-combustible appliance also includes a heat insulation component 300, which is sleeved outside the heating element assembly 200, and an airflow channel 140 is located on the outside of the heat insulation component 300. In this embodiment, by separating the airflow channel 140 from the heating element assembly 200 through the heat insulation component 300, the problem of aerosol condensation and adhesion to the side wall of the heating element assembly 200 can be avoided. It is understood that in other embodiments of this application, the gap between the heating element assembly 200 and the atomizing medium 5 can also be used as the airflow channel 140. In this case, the temperature sensor 500 can be directly connected to the heating element assembly 200, which can improve the detection accuracy of the number of suction ports by the temperature sensor 500.

[0042] In some of these embodiments, please refer to Figure 3 The temperature sensor 500 is attached to the outside of the heat insulation component 300. Although the heat insulation component 300 can isolate heat, it is still relatively hot because it is attached to the outside of the heating element assembly 200. By attaching the temperature sensor 500 to the heat insulation component 300, the temperature sensor 500 can detect a relatively high initial temperature T1 at the beginning of the heating of the non-combustible appliance.

[0043] In other embodiments of this application, please refer to Figure 7 The heat insulation component 300 has a through groove 330, through which the heat-conducting component 400 passes to connect the heating element assembly 200 and the temperature sensor 500. The through groove 330 allows the temperature sensor 500, located in the airflow channel 140, to be connected to the heating element assembly 200 via the heat-conducting component 400. The heat-conducting component 400 rapidly transfers the temperature of the heating element assembly 200 to the temperature sensor 500, ensuring the detection accuracy of the temperature sensor 500 while also isolating the airflow channel 140 from the heating element assembly 200. Specifically, the heat-conducting component 400 has a block structure, filling the through groove 330. One side of the heat-conducting component 400 is attached to the heating element assembly 200, and the other side is placed in the airflow channel 140. The temperature sensor 500 is attached to the other side of the heat-conducting component 400. Preferably, the cross-sectional dimensions of the heat-conducting element 400 are adapted to the cross-sectional dimensions of the through groove 330, thereby reducing the amount of heat transferred by the heat-conducting element 400 to spaces other than the temperature sensor 500.

[0044] Optionally, the thermal insulation element 300 may be made of aerogel material, which is a unique material known for its extremely low density and extremely high porosity, making it one of the lightest and densest solids known in the world. Due to its microstructure, aerogel is composed of almost entirely air, thus possessing excellent thermal insulation properties.

[0045] In some embodiments, please refer to Figure 3 The thermal insulation component 300 includes two aerogel layers: an inner aerogel layer 310 and an outer aerogel layer 320. The inner aerogel layer 310 is fitted over the heating element assembly 200, and the outer aerogel layer 320 is fitted over the inner aerogel layer 310. Because the aerogel has a three-dimensional network structure, the two aerogel layers improve the thermal insulation effect and block heat from different directions. Furthermore, the two aerogel layers can share the thermal insulation pressure to a certain extent, reducing the heat impact on each aerogel layer, thereby potentially extending the service life of the aerogel, reducing the frequency of replacing the thermal insulation material, and indirectly reducing usage costs. It is understood that in other embodiments of this application, the number of aerogel layers may be one, three, or more. Additionally, in other embodiments, the thermal insulation component 300 may also include an air insulation layer, glass wool, or polystyrene foam for thermal insulation.

[0046] In some embodiments, please refer to Figure 2 and Figure 3The heated non-combustible appliance also includes a housing assembly 100 fitted over the heat insulation component 300. An airflow channel 140 is formed in the housing assembly 100. The side wall of the housing assembly 100 has a mounting groove 150. A heat-conducting component 400 is disposed within a sealed cavity formed by the housing assembly 100 and the heat insulation component 300. The heat-conducting component 400 abuts against the side of the housing assembly 100 facing the heat insulation component 300 and is sealed at the end face of the mounting groove 150. A temperature sensor 500 is attached to the heat-conducting component 400 via the mounting groove 150. By placing the airflow channel 140 in the housing assembly 100, the airflow channel 140 can be separated from the heating element assembly 200, which also facilitates the formation of the airflow channel 140 and the sealing design of the airflow channel 140. Meanwhile, by sealing the heat-conducting element 400 at the end face of the mounting groove 150, not only can the temperature sensor 500 located in the airflow channel 140 be connected to the heat-conducting element 400, but the airflow channel 140 can also be sealed to prevent gas in the airflow channel 140 from entering between the housing assembly 100 and the heat insulation element 300.

[0047] In some embodiments, please refer to Figure 3 The heat-conducting element 400 abuts between the heat insulation element 300 and the housing assembly 100. The heat-conducting element 400 is sheet-shaped and seals the end face of the mounting groove 150 facing the heat insulation element 300. The temperature sensor 500 passes through the mounting groove 150 and is attached to the heat-conducting element 400, with the detection end of the temperature sensor 500 placed in the airflow channel 140. It will be understood that in other embodiments, please refer to... Figure 7 Alternatively, the housing assembly 100 can be attached to the heat insulation component 300, and the heat conduction component 400 can be installed through the heat insulation component 300. One end of the heat conduction component 400 is connected to the heating element assembly 200, and the other end of the heat conduction component 400 is attached to the side of the housing assembly 100 facing the heat insulation component 300 and sealed to the end face of the mounting groove 150.

[0048] In some embodiments, please refer to Figures 3 to 5The housing assembly 100 includes an inner shell 110, a sealing sheet 130, and an outer shell 120. The inner shell 110 is fitted over the heat insulation member 300, and the outer shell 120 is fitted over the inner shell 110. An airflow channel 140 is formed on the outer peripheral surface of the inner shell 110. The sealing sheet 130 covers the port of the airflow channel 140 facing the outer shell 120. The sealing sheet 130 and the inner shell 110 have a first air inlet 160 communicating with the airflow channel 140. The mounting groove 150 is provided through the inner shell 110. Since the inner shell 110 serves as the internal support for the heated non-combustible appliance, it needs to support the heating element, control board, and other driving structures. Therefore, the structure of the inner shell 110 is relatively complex, and its machining precision cannot be too high, otherwise it will increase manufacturing costs. Similarly, the outer shell 120 has a large structural size and cannot be precisely machined. If the airflow channel 140 is directly formed by the inner shell 110 and the outer shell 120, the airflow channel 140 will flow between the inner shell 110 and the outer shell 120, affecting the suction effect. In this embodiment, by forming the airflow channel 140 in the inner shell 110 and using a sealing plate 130 at the port of the airflow channel 140 facing the outer shell 120, the airflow channel 140 can be sealed. At the same time, the first air inlet 160 can introduce external gas into the airflow channel 140.

[0049] For details, please refer to Figure 3 and Figure 5 The inner shell 110 also has a receiving groove 111, which communicates with the airflow channel 140 and covers the airflow channel 140. A sealing sheet 130 is housed in the receiving groove 111 and is attached to the bottom wall of the receiving groove 111. The outer surface of the sealing sheet 130 is flush with the outer surface of the inner shell 110. The receiving groove 111 ensures that the surface of the inner shell 110 is flush, facilitating the assembly of the inner shell 110 and the outer shell 120.

[0050] Specifically, the sealing sheet 130 can be fixed by adhesive to ensure the sealing performance of the connection between the sealing sheet 130 and the inner shell 110.

[0051] For details, please refer to Figure 3 and Figure 5 The first air inlet 160 is formed on the outer peripheral surface of the inner shell 110. The first air inlet 160 is located above the airflow channel 140 and is connected to the airflow channel 140. The first air inlet 160 is located outside the sealing sheet 130, so that external gas can enter the airflow channel 140 through the first air inlet 160.

[0052] In some embodiments, please refer to Figure 1 and Figure 2The heated non-combustible appliance includes a main body 1, a top cover assembly 2, and a nozzle 3. The top cover assembly 2 is rotatably connected to the main body 1, and the nozzle 3 is installed on the top cover assembly 2. The top cover assembly 2 has a closed state and an open state. When the top cover assembly 2 is in the closed state, the nozzle 3 is directly opposite and connected to the heating chamber 230 along the axial direction of the heating element assembly 200. When the user inhales through the nozzle 3, external airflow enters the distal lip of the atomizing medium 5 through the airflow channel 140 and exits through the nozzle 3 for the user to inhale. When the top cover assembly 2 is in the closed state, the atomizing medium 5 can be removed from the heating chamber 230.

[0053] Please see Figure 1 The upper cover assembly 2 and the device body 1 have a second air inlet 4. External airflow enters the first air inlet 160 from between the upper cover assembly 2 and the device body 1, and passes through the airflow channel 140, the connection port 112, the connection cavity 640, and the mounting cavity 630 in sequence to enter the atomizing medium 5, and finally exits from the mouthpiece 3.

[0054] In some embodiments, please refer to Figure 2 and Figure 4 The heated non-combustible appliance also includes a first connecting seat 600, which has a mounting cavity 630 and a connecting cavity 640. The mounting cavity 630 is used to mount the distal lip end of the atomizing medium 5 and communicates with the atomizing medium 5. The connecting cavity 640 is communicated with the airflow channel 140. The first connecting seat 600 not only supports the distal lip end of the atomizing medium 5 but also allows the airflow channel 140 to introduce the atomizing medium 5 through the distal lip end, thereby carrying away the aerosol generated by the heated non-combustible atomizing medium 5.

[0055] Specifically, the mounting cavity 630 is cylindrical, and the distal lip of the atomizing medium 5 is inserted into the mounting cavity 630. One end of the heating element assembly 200 along its axial direction is mounted at the port of the mounting cavity 630. The connecting cavity 640 is located outside the mounting cavity 630, and the first connecting seat 600 has multiple connecting holes 650, each connecting hole 650 for communicating with the connecting cavity 640 and the mounting cavity 630.

[0056] In some specific embodiments, the first connecting seat 600 includes a first seat body 610 and a second seat body 620. The first seat body 610 and the second seat body 620 are sealed and abutted along the axial direction (the axial direction of the heating element assembly 200, hereinafter referred to as the axial direction) and together enclose to form a connecting cavity 640. The mounting cavity 630 is formed in the first seat body 610, and the second seat body 620 is connected to the inner shell 110.

[0057] Specifically, the heated non-combustible appliance also includes a first seal 800 and a second seal 900. The first seal 800 abuts between the first seat 610 and the second seat 620, and the second seal 900 abuts between the housing assembly 100 and the first connecting seat 600 to form a sealed connection between the airflow channel 140 and the connecting cavity 640.

[0058] Specifically, the inner shell 110 has a connection port 112 at the position corresponding to the connection cavity 640, and the airflow channel 140 is connected to the connection cavity 640 through the connection port 112.

[0059] In some embodiments, please refer to Figure 2 The heated non-combustible appliance also includes a second connecting seat 700. The second connecting seat 700 and the first connecting seat 600 are respectively installed at opposite ends of the heating element assembly 200 along the axial direction. The opposite ends of the heating element assembly 200 along the axial direction are respectively installed at the first connecting seat 600 and the second connecting seat 700. The heating element assembly 200 can be supported by the first connecting seat 600 and the second connecting seat 700.

[0060] In some embodiments, please refer to Figure 6 The heating element assembly 200 includes a housing structure 210 for accommodating the atomizing medium 5 and a heating film 220 attached to the outer surface of the housing structure 210. The heating film 220 includes a first heating segment 221 and a second heating segment 222. After the heating film 220 is energized, the first heating segment 221 heats up before the second heating segment 222. The distance from the temperature sensor 500 to the first heating segment 221 is less than the distance from the temperature sensor 500 to the second heating segment 222. In other words, by installing the temperature sensor 500 near the position where the heating element assembly 200 heats up first, the temperature sensor 500 can heat up quickly, thereby improving the detection sensitivity of the temperature sensor 500.

[0061] Specifically, the first heating segment 221 and the second heating segment 222 are distributed along the axial direction of the heating element assembly 200. Along the axial direction of the heating element assembly 200, the distance from the temperature sensor 500 to the first heating segment 221 is less than the distance from the temperature sensor 500 to the second heating segment 222, so that the heat of the first heating segment 221 can be quickly conducted to the temperature sensor 500.

[0062] Preferably, the heating film 220 includes two first heating segments 221, and the two first heating segments 221 and the second heating segment 222 are sequentially distributed along the axial direction of the heating film 220. A temperature sensor 500 is attached to one of the first heating segments 221 or between the two first heating segments 221, or the temperature sensor 500 is attached to the heat-conducting element 400, and the axial position of the temperature sensor 500 is located between the two first heating segments 221. It should be noted that the heating sequence of the first heating segments 221 and the second heating segment 222 can be controlled by the internal circuitry and software of the heating film 220.

[0063] In some other embodiments of this application, the heating structure may not be the heating element assembly 200, but rather other structures may be used to heat the temperature sensor 500. Specifically, the heated non-combustible appliance includes the heating element assembly 200 and a heating device, with the heating cavity 230 formed in the heating element assembly 200, and the heating device including a heating structure. In this embodiment, the temperature sensor 500 is heated by an additional heating device to improve the accuracy of the suction port detection of the temperature sensor 500. With this configuration, it is not necessary to connect the temperature sensor 500 to the heating element assembly 200, and the heating device only needs to heat the temperature sensor 500, thus simplifying the structure of the temperature sensor 500.

[0064] Optionally, the heating device may include a heating copper foil, a heating wire, or a heating resistor, as long as it can generate heat after being powered on and transfer the heat to the temperature sensor 500.

[0065] Optionally, the heating element can be directly placed in the airflow channel 140 to heat the temperature sensor 500, or it can be installed between the inner shell 110 and the heat insulation member 300 to heat the temperature sensor 500. In this way, the temperature of the temperature sensor 500 can be quickly increased by the heating element to improve the detection accuracy of the number of suction ports. Alternatively, the heating element can be placed close to the heating element assembly 200 to facilitate electrical connection between the heating element and the control board.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
