Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0033] See Figure 1-9 , an embodiment of the present invention provides a temperature measuring device for detecting the inner wall temperature of the heating chamber or tubular heating element 10 of an electronic atomization device, the temperature measuring device comprising: a pipe 1, an inner support 2 and a temperature measuring element 3; the inner support 2 is passed through the pipe 1; the temperature measuring element 3 comprises a temperature measuring portion 31 and a lead portion 32, the temperature measuring portion 31 is connected to one end of the lead portion 32, and the lead portion 32 is partially located in the pipe 1 and connected to the inner support 2; a mounting hole 11 extending radially along the pipe 1 is provided on the circumference of the pipe 1, and the temperature measuring element 3 is passed through the mounting hole 11, wherein the temperature measuring portion 31 can move radially along the pipe 1, and at least a portion of the temperature measuring portion 31 away from the lead portion 32 protrudes outside the mounting hole 11, so as to be used for contacting the inner wall of the heating chamber or the heating element 10.

[0034] In this embodiment, the temperature measuring device includes a pipe 1, an inner support 2 and a temperature measuring part 3, wherein the temperature measuring part 3 includes a temperature measuring portion 31 and a lead portion 32. The lead portion 32 is connected to the inner support 2, and the inner support 2 can support and limit the lead portion 32. The temperature measuring device is applied to an electronic atomization device. During the temperature measurement process, the temperature measuring part 31 is fixed to the mounting hole 11 and at least partially protrudes from the mounting hole 11. Therefore, the temperature measuring part 31 protruding from the mounting hole 11 can be used to contact and connect with the inner wall of the heating chamber or the heating element 10, so that the temperature measuring part 31 can measure the temperature value of the heating chamber or the heating element 10 at the contact point, and there is no need to hold the temperature measuring part 3, which can avoid measurement errors caused by hand shaking.

[0035] During the process of assembling the temperature measuring device in the heating cavity or tubular heating element 10, the temperature measuring part 3 is passed through the mounting hole 11. Since the temperature measuring part 31 can move radially along the pipe 1 in the mounting hole 11. If the inner diameter of the heating cavity or tubular heating element 10 is large, the temperature measuring part 31 can move radially toward the inner wall of the heating cavity or heating element 10 along the diameter of the tube, so that the temperature measuring part 31 can finally be in close contact with the heating element 10; on the contrary, if the inner diameter of the heating cavity or tubular heating element 10 is small, the temperature measuring part 31 moves in the opposite direction of the diameter of the tube, so that the temperature measuring device can be assembled in the heating cavity or tubular heating element 10, and the temperature measuring part 31 is in close contact with the heating element 10. Therefore, the temperature measuring device of the present invention can be applied to heating cavities or tubular heating elements 10 of different diameters, and has the characteristics of a wide range of applications. At the same time, during the temperature measurement process, the temperature measuring part 31 can stably contact with the heating element 10. Therefore, the temperature measuring device also has the effect of high measurement accuracy, which greatly improves the user experience.

[0036] Further, see Figure 1 、 Figures 3 to 7 The temperature measuring device further includes a shrinking member 4, the temperature measuring portion 31 is assembled on the shrinking member 4, and the shrinking member 4 is used to provide elastic force for the temperature measuring portion 31 to protrude from the mounting hole.

[0037] Specifically, in some embodiments, the shrinking member 4 includes a sliding block that can be slidably connected to the mounting hole 11, and the temperature measuring part 31 is fixed to the sliding block of the shrinking member 4. Therefore, when the sliding block of the shrinking member 4 moves radially relative to the mounting hole 11, the temperature measuring part 31 can also move radially relative to the mounting hole 11. When the sliding block is acted upon by an external force and moves radially toward the inside of the pipe 1, the sliding block drives the temperature measuring portion 31 to move toward the inside of the pipe 1. The temperature measuring device can be installed in a heating cavity or tubular heating element 10 with a smaller inner diameter, and the temperature measuring portion 31 protruding from the mounting hole 11 can contact the inner wall of the heating cavity or heating element 10. In addition, the shrinking piece 4 can provide elastic force for the temperature measuring portion 31 to protrude from the mounting hole 11. Therefore, when the temperature measuring device is installed in a heating cavity or tubular heating element 10 with a larger inner diameter, the shrinking piece 4 drives the temperature measuring portion 31 to move along the outside of the pipe 1, so that more of the temperature measuring portion 31 protrudes from the mounting hole 11, and the temperature measuring portion 31 can contact the inner wall of the heating cavity or heating element 10. Therefore, the temperature measuring device can be applied to electronic atomization devices with heating cavities or tubular heating elements of different diameters, has a wide range of applications, and improves user experience.

[0038] Further, in some embodiments, see Figures 4 to 7 The shrinking member 4 includes a shell 41, a first cover 42, a second cover 43 and an elastic member 44; the first cover 42 and the second cover 43 are arranged at both ends of the shell 41, one end of the elastic member 44 abuts against the first cover 42 and the other end abuts against the second cover 43; the outer peripheral side of the shell 41 abuts against the hole wall of the mounting hole 11, and the first cover 42 is fixed to the pipe 1; the shell 41, the first cover 42 and the second cover 43 are all provided with a communicating through-hole, the lead part 32 is partially passed through the through-hole, one side of the temperature measuring part 31 abuts against the second cover 43 and the other side is exposed outside the second cover 43.

[0039] Specifically, the shell 41 and the first cover 42 in the shrinking member 4 are both relatively fixed to the mounting hole 11, and the shell 41 and the first cover 42 can both be fixed blocks of the shrinking member 4; and the second cover 43 serves as a sliding block of the shrinking member 4, which is used to be slidably connected to the mounting hole 11, and the second cover 43 can move radially along the pipe 1 relative to the mounting hole 11; and the radial movement of the second cover 43 toward the outside of the pipe 1 is achieved by relying on the reset force of the elastic member 44.

[0040] The housing 41 is a hollow columnar structure, embedded in the mounting hole 11. The first cover 42 is located at one end of the housing 41 and is clamped between the housing 41 and the outer wall of the pipe 1. The second cover 43 is arranged opposite the first cover 42, with a portion of the second cover 43 being sheathed within the housing 41 and a portion being exposed outside the housing 41. The second cover 43 can move radially relative to the pipe 1 along the housing 41. The elastic member 44 can be a spring, with one end of the spring abutting the first cover 42 and the other end abutting the second cover 43. See Figure 6 and Figure 7 When the temperature measuring device is installed in a heating cavity or tubular heating element 10 with a smaller diameter, the second cover 43 is pushed to move inward along the radial direction of the pipe 1, and the spring is compressed; see Figure 4 and Figure 5 When the temperature measuring device is installed in a heating cavity or tubular heating element 10 with a larger diameter, the second cover 43 can make an opposite radial movement, and the spring in the compressed state can return to its original state. In the process of returning to its original state, the spring pushes the second cover 43 to move radially toward the outside of the pipe 1 along the pipe 1.

[0041] See Figure 6 and Figure 7 If the inner diameter of the heating chamber or the tubular heating element is small, the second cover 43 can be pushed to move radially inward of the tube 1. The second cover 43 drives the temperature measuring part 31 to move in the same direction, and the elastic member 44 is compressed. The temperature measuring device can be smoothly assembled into the electronic atomization device, and the temperature measuring part 31 can be closely attached to the heating element 10. Figure 4 and Figure 5 If the inner diameter of the heating cavity or the tubular heating element 10 is large, the elastic member 44 in the compressed state can have space to return to its original state. The elastic member 44 provides a reset force to the second cover 43 and the temperature measuring part 31, so that the second cover 43 and the temperature measuring part 31 can move radially toward the inner wall of the heating cavity or the tubular heating element 10 along the diameter of the tube, and the temperature measuring part 31 can be in close contact with the heating element 10. Therefore, the temperature measuring device of the present invention is applicable to electronic atomization devices of different diameters and has a wide range of applications. At the same time, during the temperature measurement process, the temperature measuring part 31 can always be kept in stable contact and close contact with the heating element 10. Therefore, the temperature measuring device also has the effect of high measurement accuracy, greatly improving the user experience.

[0042] It should be understood that the lead portion 32 has a certain degree of flexibility. Therefore, when the elastic member 44 is compressed and the elastic member 44 drives the temperature measuring portion 31 and the second cover 43 to move radially inward from the tube 1, the lead portion 32 connected to the temperature measuring portion 31 will be compressed and partially deformed. When the elastic member 44 gradually returns to its original shape, the lead portion 32 also gradually returns to its original shape. In addition, the elastic member 44 plays a primary role in the retracting member 4. The housing 41, first cover 42, second cover 43, and other structures of the retracting member 4 are all part of the assembly structure of the elastic member 44. In some embodiments, the retracting member 4 can be a single elastic member 44, such as a spring.

[0043] Further, see Figure 5 and Figure 7 A positioning column 45 extending along the radial direction of the pipe 1 is provided on the side of the first cover body 42 close to the second cover body 43, and / or a positioning column 45 extending along the radial direction of the pipe 1 is provided on the side of the second cover body 43 close to the first cover body 42, and the elastic member 44 is a spring, and the spring is sleeved outside the positioning column 45.

[0044] Specifically, in this embodiment, the first cover 42 includes two hollow columnar structures with unequal cross-sectional diameters. In the first cover 42, the columnar structure with a larger cross-sectional diameter and a smaller thickness abuts against the housing 41 on one side and against the outer circumference of the pipe 1 on the other side, while the columnar structure with a smaller cross-sectional diameter and a larger thickness is located within the clearance hole of the housing 41, and the columnar structure can serve as a positioning column 45 for sleeved springs, thereby stably fixing the spring within the clearance hole, and the positioning column 45 extends along the radial direction of the pipe 1 (with a larger thickness). Therefore, the spring can be quickly compressed or quickly reset during compression or reset along the radial direction of the pipe 1, and the spring will not deform toward other positions.

[0045] The second cover 43 also includes two hollow columnar structures with unequal cross-sections. Figure 5 and Figure 7 The columnar structure with a small cross-sectional diameter but a large thickness in the second cover 43 is used to fix the temperature measuring part 31. The temperature measuring part 31 can be spherical, and the spherical diameter of the temperature measuring part 31 is larger than the diameter of the cross-sectional area of ​​the columnar structure. Therefore, the columnar structure can be used to fix the temperature measuring part 31. The temperature measuring part 31 can be embedded in the top surface of the columnar structure, which can achieve relative stability between the temperature measuring part 31 and the second cover 43. In addition, part of the temperature measuring part 31 can be exposed outside the second cover 43, so that the temperature measuring part 31 can be used to measure the temperature of the heating element 10. When the elastic member 44 is not compressed, please refer to Figure 5The columnar structure with a large cross-sectional diameter and a small thickness in the second cover 43 is located in the clearance hole of the shell 41, while the columnar structure with a small cross-sectional diameter and a large thickness in the second cover 43 can be partially located in the clearance hole of the shell 41 and partially protrude outside the clearance hole of the shell 41. Figure 7 When the elastic member 44 is compressed, the position of the second cover body 43 in the clearance hole of the shell 41 will change. The second cover body 43 can be completely located in the clearance hole of the shell 41, and its columnar structure with a large diameter can abut against the first cover body 42.

[0046] Further, in some embodiments, see Figure 2 and Figure 8 The shrinking member 4 includes an elastic arm 5 provided on the pipe 1 and located outside the mounting hole 11 . One side of the elastic arm 5 is connected to the pipe 1 , and the other end abuts against the side where the temperature measuring portion 31 is connected to the lead portion 32 .

[0047] Specifically, the elastic arm 5 is integrally formed with the pipe 1. In actual application, there may be a small gap between the temperature measuring part 31 of the temperature measuring device and the inner wall of the heating chamber or the heating element 10, which may lead to inaccurate temperature measurement and cause differences in the measurement results. Since the temperature measuring part 31 protrudes from the mounting hole 11, and the elastic arm 5 abuts against the side of the lead part 32 of the temperature measuring part 31, if there is a small gap between the temperature measuring part 31 and the inner wall of the heating chamber or the heating element 10, the elastic arm 5 can push the temperature measuring part 31 to move a small displacement along the radial direction of the pipe 1, thereby eliminating the small gap, making the temperature measuring part 31 and the heating chamber or the heating element 10 fit tightly, and improving the measurement accuracy.

[0048] Furthermore, in some embodiments, two opposing elastic arms 5 are provided on the outside of each mounting hole 11 of the pipe fitting 1. Through the joint pushing action of the two elastic arms 5, the temperature measuring part 31 is driven to move a small displacement along the radial direction of the pipe fitting 1, thereby eliminating the small gap, making the temperature measuring part 31 and the heating chamber or heating element 10 fit tightly, thereby improving the measurement accuracy.

[0049] In some embodiments, the pipe 1 may be a conical ring structure surrounding the outer circumference of the mounting hole 11 .

[0050] Further, see Figure 2 and Figure 8 The elastic arm 5 bends and extends from the outer wall of the pipe 1 toward the mounting hole 11.

[0051] Specifically, a gap connecting the mounting hole 11 is formed between the two elastic arms 5, and the lead portion 32 connected to the temperature measuring portion 31 is inserted between the mounting hole 11 and the gap. The temperature measuring portion 31 is arranged on the outside of the two elastic arms 5. The two elastic arms 5 are formed with a certain curvature and are both bent in the direction of the gap, so that the two elastic arms 5 can jointly clamp a temperature measuring portion 31. The temperature measuring portion 31 can be slightly displaced along the radial direction of the pipe 1 under the action of the passing of the two elastic arms 5, so that it can fit tightly against the heating element 10 in the second state, thereby improving the measurement accuracy.

[0052] Further, see Figure 9 The inner support member 2 is recessed inward to form a limiting groove 21, and the lead portion 32 is partially accommodated in the limiting groove 21. Specifically, the lead portion 32 includes a bending portion connected to the temperature measuring portion 31, and a main body portion having an angle relationship with the bending portion.

[0053] In this embodiment, the bent portion and the main body of the lead portion 32 are arranged perpendicularly, wherein the bent portion is inserted through the mounting hole 11 and the gap between the two elastic arms 5, or the bent portion is inserted through the clearance holes of the first cover body 42, the second cover body 43, and the shell 41. When the temperature measuring portion 31 moves in the radial direction of the pipe 1, the bent portion will deform or return to its original shape. The limiting groove 21 extends along the axial direction of the pipe 1, and the main body is perpendicularly connected to the end of the bent portion away from the temperature measuring portion 31. The main body is accommodated in the limiting groove 21, so that the limiting groove 21 can support and limit the main body, thereby preventing entanglement and interference between different lead portions 32 of different temperature measuring components 3.

[0054] In some embodiments, the temperature measuring element 3 is a thermocouple, and the thermocouple may be of type K, type S, or type T.

[0055] In some embodiments, see Figure 1 、 Figures 3 to 7 When the shrinking member 4 is an elastic member 44 or the like, when assembling the temperature measuring device, the shrinking member 4 can be first installed at the mounting hole 11, and then the lead portion 32 of the temperature measuring member 3 can be passed through the first cover 42, the second cover 43, and the through-holes of the housing 41. The temperature measuring portion 31 is then fixed to the second cover 43 of the shrinking member 4, and the lead portion 32 is arranged. Finally, the lead portion 32 is inserted into the inner support member 2 and accommodated in the limiting groove 21. Finally, the temperature measuring device is applied to the electronic atomization device as a whole. The heating element 10 can be a columnar structure, and the temperature measuring portion 31 faces the inner wall of the heating element 10.

[0056] In some embodiments, see Figure 2 and Figure 8When the shrinking member 4 is integrally formed with the elastic arm 5 of the tube 1, when assembling the temperature measuring device, the lead portion 32 of the temperature measuring member 3 is directly passed through the gap between the two elastic arms 5 and the mounting hole 11. The temperature measuring portion 31 is then abutted against the elastic arm 5, and the lead portion 32 is arranged. Finally, the inner support member 2 is inserted and the lead portion 32 is accommodated in the limiting groove 21. Finally, the temperature measuring device is applied to the electronic atomization device as a whole. The heating element 10 can be a columnar structure, and the temperature measuring portion 31 faces the inner wall of the heating element 10.

[0057] Therefore, the temperature measuring device of the present invention has a simple assembly relationship and is easy to operate during the temperature measurement process. It can accurately measure the temperature of a specific position of the heating element 10 with high measurement efficiency.

[0058] Further, see Figures 1 to 3 , Figure 4 、 Figure 6 and Figure 8 , m mounting holes 11 are provided on the circumferential side of the pipe fitting 1, and the m mounting holes 11 are distributed at intervals along the axial direction of the pipe fitting 1, and / or, the m mounting holes 11 are distributed at intervals along the circumferential direction of the pipe fitting 1; the temperature measuring device includes n temperature measuring components 3, m≥n, and the temperature measuring components 3 are one-to-one corresponding and can be detachably installed in the mounting holes 11.

[0059] Specifically, a plurality of mounting holes 11 may be provided on the circumference of the pipe 1, and the plurality of mounting holes 11 may be spaced apart along the axial direction of the pipe 1, or spaced apart along the circumference of the pipe 1, or spaced apart along both the axial direction and the circumference of the pipe 1. By providing a plurality of mounting holes 11, when the temperature measuring element 3 is connected to different mounting holes 11, multiple temperature measurement points may be provided, thereby enabling the temperature at different positions of the heating element 10 to be measured.

[0060] In some embodiments, there may be multiple temperature measuring elements 3, with one temperature measuring element 3 connected to one mounting hole 11. Thus, a single temperature measuring device can simultaneously measure the temperature at different locations on the heating element 10. For example, in the axial direction of the pipe 1, the temperature at locations at the same depth but different radial directions on the heating element 10 can be measured simultaneously; the temperature at locations at different depths but the same radial direction on the heating element 10 can also be measured; and the temperature at locations at different depths but different radial directions on the heating element 10 can also be measured. Because the temperature measuring element 3 and the pipe 1 are removable and reassembled, temperature measurement points can be flexibly added or adjusted as needed.

[0061] In some embodiments, one mounting hole 11 corresponds to one compression piece, and each mounting hole 11 is provided with a corresponding compression piece; or, since the compression piece and the mounting hole 11 are also detachably assembled, the number and setting position of the compression piece can be flexibly increased or adjusted according to needs, that is, the compression piece is assembled in the mounting hole 11 only when the temperature measuring piece 3 needs to be connected.

[0062] In some embodiments, one mounting hole 11 is provided with two elastic arms 5 , each mounting hole 11 may be provided with two elastic arms 5 , or some mounting holes 11 may be provided with elastic arms 5 , and some mounting holes 11 may be used to connect compression parts.

[0063] Furthermore, the material of the pipe 1 can be high-temperature resistant silicone or plastic; the material of the inner support 2 can also be high-temperature resistant silicone or plastic. Specifically, the pipe 1 can be silicone or plastic with a temperature resistance of approximately 300°C; the inner support 2 can be silicone or plastic with a temperature resistance of approximately 300°C. The shrinking member 4 can be made of metal.

[0064] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
