In addition, the technical features mentioned in the different embodiments of the application described below can be combined with one another as long as they do not conflict with one another.
Referring to fig. 1, the present application provides a temperature sensing assembly 100 adapted for an aerosol-generating device, the temperature sensing assembly 100 being adapted for receiving at least part of an aerosol-generating article 200 and for sensing a temperature of an end of the aerosol-generating article 200, thereby enabling temperature control of heating the aerosol-generating article 200.
Referring to fig. 2 and 3, the temperature measuring assembly 100 includes a support tube 10, a temperature measuring element 20 and a fixing member 30. The support tube 10 is internally provided with a receiving chamber 11 for receiving at least a partial portion of the aerosol-generating article 200, the receiving chamber 11 having oppositely arranged mouth 12 and bottom 13, wherein the mouth 12 is adapted to insert the aerosol-generating article 200 into the receiving chamber 11 and the bottom 13 is adapted to abut an end portion of the aerosol-generating article 200 in order to retain the aerosol-generating article 200. A temperature measuring element 20 is connected to the support tube 10, the temperature measuring element 20 being used for measuring the temperature of the end of the aerosol-generating article 200. The fixing piece 30 is respectively connected with the support tube 10 and the temperature measuring element 20, and the fixing piece 30 is used for fixing the temperature measuring element 20 on the support tube 10, so that the temperature measuring of the end part of the aerosol generating product 200 is prevented from being influenced due to the fact that the temperature measuring element 20 moves relative to the support tube 10 during temperature measurement.
As an example, as shown in fig. 3, the temperature measuring element 20 includes a probing head 21 and a flexible cable 22. The detection head 21 is arranged at the cavity bottom 13 of the accommodating cavity 11, one end of the flexible cable 22 is electrically connected with the detection head 21, and the other end of the flexible cable 22 is electrically connected with an external power supply component, so that temperature information detected by the detection head 21 is obtained. Meanwhile, the fixing member 30 is beneficial to the installation and fixation of the temperature measuring element 20, because the detecting head 21 is arranged at one end of the flexible cable 22, when the detecting head 21 and the flexible cable 22 are required to be installed at the corresponding positions, the flexible cable 22 is soft and easy to deform and is not easy to fix because of the characteristics of the flexible cable 22. By providing the fixing member 30, the form of the flexible cable 22 can be maintained, thereby facilitating the installation and fixing of the temperature measuring element 20. In some embodiments, referring to fig. 3 and 4, the support tube 10 is provided with a connection channel 14, the connection channel 14 communicates the bottom 13 of the accommodating chamber 11 with the outside, and at least part of the flexible cable 22 is disposed in the connection channel 14 such that the detection head 21 connected to one end of the flexible cable 22 is flush with the bottom 13 of the accommodating chamber 11, or the detection head 21 is lower than the bottom 13 of the accommodating chamber 11, i.e., the detection head 21 is located in the connection channel 14. Since the flexible cable 22 is flexible and easy to deform, by arranging the flexible cable 22 in the connecting channel 14 and the detecting head 21 does not protrude into the accommodating cavity 11, the detecting head 21 can be prevented from being pushed to move when the aerosol-generating article 200 is inserted into the accommodating cavity 11, and the detecting head 21 and the flexible cable 22 are prevented from being broken. In one possible embodiment, the temperature sensing assembly 100 further includes a package 40. The encapsulation 40 covers the end of the connecting channel 14 adjacent to the receiving chamber 11 to avoid that oil or oil residues adhere to the outer surface of the detection head 21 during the aerosol generating article 200 during the aerosol generation process, affecting the performance of the detection head 21.
In other embodiments, as shown in FIG. 5, at least a portion of the securing member 30 is captured within the connection channel 14, and the securing member 30 encases the flexible cable 22 to secure the flexible cable 22 within the connection channel 14. Wherein the fixing member 30 has a first end 31, and the first end 31 protrudes from the connecting channel 14 into the accommodating chamber 11, i.e. the first end 31 of the fixing member 30 protrudes from the bottom 13 of the accommodating chamber 11, and the detecting head 21 is disposed at the first end 31 of the fixing member 30, i.e. the detecting head 21 also protrudes from the bottom 13 of the accommodating chamber 11. The fixing members 30 fix the detection head 21 and the flexible cable 22, respectively, with respect to the support pipe 10, preventing the detection head 21 from shaking in the accommodation chamber 11. When the aerosol-generating article 200 is inserted into the receiving cavity 11, the detection head 21 may be inserted into the interior of the aerosol-generating article 200 through the end of the aerosol-generating article 200, thereby acquiring the temperature of the end of the aerosol-generating article 200, further improving the accuracy of the temperature detection.
In some embodiments, as shown in fig. 5, the probing head 21 protrudes beyond the first end 31 of the fixture 30, i.e., the probing head 21 is closer to the cavity mouth 12 of the receiving cavity 11 than the end face of the first end 31. With the above structure, the detection head 21 can be directly exposed in the accommodating chamber 11, and when the aerosol-generating article 200 is inserted into the accommodating chamber 11, the detection head 21 can directly abut against the inside of the aerosol-generating article 200, and the measured data thereof are more accurate.
In other embodiments, the probing head 21 is flush with the first end 31 of the fixture 30; or the detection head 21 is lower than the first end 31 as shown in fig. 6, i.e. the detection head 21 is farther away from the mouth 12 of the receiving chamber 11 than the end face of the first end 31. In one possible embodiment, the temperature measurement assembly 100 further includes a package 40, the package 40 covering the first end 31 of the fixture 30 to prevent oil or oil residue from adhering to the outer surface of the detection head 21 during aerosol generation of the aerosol-generating article 200, affecting the performance of the detection head 21.
In some embodiments, referring to fig. 4, the fixing member 30 further includes a middle portion 32 and a second end portion 33, where the first end portion 31 and the second end portion 33 are respectively connected to two ends of the middle portion 32 to form a U-shaped structure, where the first end portion 31 is at least partially located at the bottom 13 of the accommodating cavity 11, the middle portion 32 is at least partially located in the connecting channel 14, and the second end portion 33 is at least partially located outside the support tube 10.
In some embodiments, as shown in fig. 1, the first end 31 of the fixture 30 protrudes from the center of the cavity bottom 13 of the receiving cavity 11, i.e. the detection head 21 is located at the center of the cavity bottom 13, such that the detection head 21 may be caused to measure the temperature of the central region of the end of the aerosol-generating article 200. In other embodiments, as shown in FIG. 7, when the temperature measuring assembly 100 heats the aerosol-generating article 200 with a centrally inserted heating rod, the heating rod is located in a central region of the cavity bottom 13, and at this time, the detection head 21 of the temperature measuring element 20 may be disposed in a non-central region of the cavity bottom 13, i.e. between the tube wall of the support tube 10 and the heating rod.
In some embodiments, referring to fig. 3 and 4, the outer wall surface of the support tube 10 is further provided with a groove 15, the groove 15 extends along the axial direction of the support tube 10, or forms a spiral structure around the outer wall surface of the support tube 10, the groove 15 is communicated with the connection channel 14, so that at least a partial second end 33 of the fixing member 30 can be buried in the groove 15, and the flexible cable 22 penetrating from the second end 33 can be routed in the groove 15, thereby facilitating the installation and positioning of the flexible cable 22, and avoiding the flexible cable 22 protruding out of the outer wall surface of the support tube 10 from affecting the assembly of the support tube 10 with external components.
In some embodiments, referring to fig. 3, the support tube 10 further has a flange portion 16, where the flange portion 16 is disposed at an end of the support tube 10 near the cavity 12, and the flange portion 16 is used for abutting the support tube 10 with an external member to support and fix the support tube 10.
In some embodiments, referring to fig. 1 and 2, the temperature measuring assembly 100 further includes a connection terminal 50, the connection terminal 50 is disposed on the flange portion 16, the connection terminal 50 is electrically connected to the other end of the flexible cable 22, and the connection terminal 50 is electrically connected to the connection terminal 50 outside, so that the probe head 21 can perform a temperature measuring operation.
The present application further provides an embodiment of an aerosol-generating device, where the aerosol-generating device includes the above-mentioned temperature measuring assembly 100, and the specific structure and function of the temperature measuring assembly 100 may refer to the above-mentioned embodiment and will not be described herein.
The temperature measuring assembly 100 of the embodiment of the present application includes a support tube 10, a temperature measuring element 20, and a fixing member 30.
