[0042] Example:

[0043] See also Figure 1-11 A temperature measuring device is used to detect the temperature of a heating element 100 of an electronic atomization device. The temperature measuring device includes: a tube body 1, a temperature measuring element 2, and a connecting element 3 connecting the tube body 1 and the temperature measuring element 2; the temperature measuring element 2 has a temperature measuring head 21 in contact with the heating element 100; the connecting element 3 can be adjustably arranged at different positions on the tube body 1 to change the position of the temperature measuring element 2 on the tube body 1 and adjust the contact position between the temperature measuring head 21 and the heating element 100.

[0044] In this embodiment, the temperature measuring component 2 is provided with a temperature measuring head 21 that can be in contact with the heating element 100, and the temperature of the heating element 100 at the contact position can be measured by the temperature measuring component 2. During the temperature detection process, the temperature measuring component 2 is assembled to the tube body 1 through the connecting component 3, so there is no need to hold the temperature measuring component 2, which can avoid measurement errors caused by hand shaking and improve measurement accuracy. Furthermore, by adjusting the different positions of the connecting component 3 on the tube body 1, the different positions of the temperature measuring component 2 on the tube body 1 can be changed, that is, the connecting component 3 can drive the temperature measuring component 2 to adjust the contact position with the heating element 100, so that the temperature of different positions of the heating element 100 can be detected, which is convenient for users to obtain the temperature distribution on the heating element 100.

[0045] For further information, see Figure 1-11 The tube body 1 is provided with at least two assembly structures spaced apart in the axial direction and / or the circumferential direction, and the connector 3 is detachably and / or movably assembled on the assembly structures to adjust the position of the connector 3 on the tube body 1.

[0046] Specifically, a plurality of assembly structures are provided on the tube body 1. On the one hand, by changing the connection member 3 on different assembly structures, the connection member 3 can be arranged at different positions on the tube body 1, and the temperature measuring member 2 can detect the temperature of different positions of the heating element 100. For example, in some embodiments, each assembly structure is arranged at intervals along the axial direction of the tube body 1, and the temperature measuring member 2 detects different positions of the heating element 100 in the axial direction by setting the connection member 3 on different assembly structures. In some embodiments, each assembly structure is arranged at intervals along the circumference of the tube body 1. By setting the connection member 3 on different assembly structures, the temperature measuring member 2 detects different positions of the heating element 100 in the circumferential direction. In some embodiments, some assembly structures are arranged at intervals along the axial direction of the tube body 1, and some assembly structures are arranged at intervals along the circumferential direction of the tube body 1. By setting the connection member 3 on different assembly structures, the temperature measuring member 2 can detect different positions of the heating element 100 in the axial direction, and can also detect different positions of the heating element 100 in the circumferential direction. On the other hand, by adjusting the connection member 3 at different positions of the same assembly structure, the connection member 3 can be arranged at different positions on the tube body 1, and the temperature measuring member 2 can detect the temperature of different positions of the heating element 100 in the axial direction.

[0047] Specifically, in some embodiments, see Figure 1-3 , the connection between each assembly structure and the connector 3 is a detachable connection. A connector 3 can be detachably assembled to different assembly structures arranged at intervals, and the assembly structures are arranged at intervals along the axial direction and / or circumferential direction of the tube body 1. By disassembling and assembling the connector 3 on different assembly structures, the connector 3 can be set at different axial and / or circumferential positions on the tube body 1, and then the temperature measuring component 2 can detect the temperature of different axial and / or circumferential positions of the heating element 100.

[0048] It is understandable that, for the multiple assembly structures provided on the tube body 1, the multiple assembly structures can also be simultaneously equipped with connectors 3, and each connector 3 is connected to a temperature measuring component 2, so that the temperature measuring device can simultaneously measure the temperature of the object to be measured, such as the temperature of multiple different positions of the heating element 100, thereby obtaining the temperature distribution on the heating element 100. Of course, the user can selectively set the connector 3 and the temperature measuring component 2 on the assembly structures at more than two different positions of the tube body 1, so as to detect the temperature of more than two temperature measuring points on the heating element 100.

[0049] In some embodiments, see Figure 5 , Figure 6 , Figure 8 and Fig.10, one assembly structure corresponds to one connector 3, and the connection mode between each assembly structure and the connector 3 is a movable connection. One connector 3 is movably connected to the same assembly structure, and by moving the connector 3, the different positions of the connector 3 on the assembly structure can be adjusted, so that the position of the connector 3 on the tube body 1 can be changed, and the measuring position of the temperature measuring element 2 on the heating element 100 can be flexibly and quickly adjusted, which is convenient and fast, improves the measurement efficiency, simplifies the measurement process, and greatly improves the user experience.

[0050] In some embodiments, see Figure 5-8 and Fig.11 For the same assembly structure, the connector 3 is both a detachable connection method and a movable connection method. One assembly structure may correspond to one connector 3, or one connector 3 may be installed to different assembly structures. In the same assembly structure, firstly, by moving the connector 3, the different positions of the connector 3 on the assembly structure can be adjusted, and then the connector 3 is fixedly assembled at a specific position on the assembly structure, and the temperature at different positions of the heating element 100 can also be detected. Furthermore, since each assembly structure is arranged at intervals along the axial and / or circumferential direction of the tube body 1, by arranging the connector 3 on different assembly structures, it is also possible to arrange the connector 3 at different axial and / or circumferential positions on the tube body 1, and the temperature at different axial and / or circumferential positions of the heating element 100 can be detected.

[0051] In some embodiments, see Figure 1-11 A plurality of assembly structures are arranged on the tube body 1, wherein the connection mode between some of the assembly structures and the connecting member 3 is a detachable connection, that is, one connecting member 3 can be detachably assembled on assembly structures arranged at different intervals; the connection mode between some of the assembly structures and the connecting member 3 is a movable connection, that is, one connecting member 3 can be movably connected to the same assembly structure; and some of the assembly structures and the connecting member 3 are both detachably connected and movably connected.

[0053] In some embodiments, see Figure 1-11 A plurality of assembly structures are arranged on the tube body 1, wherein the connection between some of the assembly structures and the connector 3 is a detachable connection, that is, one connector 3 can be detachably assembled on assembly structures arranged at different intervals; some of the assembly structures and the connector 3 are both detachably connected and movably connected.

[0054] In some embodiments, see Figure 1-11 A plurality of assembly structures are arranged on the tube body 1, wherein the connection between some of the assembly structures and the connector 3 is a movably connected connection, that is, one connector 3 is movably connected to the same assembly structure; and some of the assembly structures and the connector 3 are both detachably connected and movably connected.

[0055] For further information, see Figure 1-11 At least one assembly structure is extended along the axial direction and / or circumferential direction of the tube body 1 , and the connecting member 3 can move relative to the tube body 1 along the extension direction of the assembly structure, thereby driving the temperature measuring member 2 to move relative to the tube body 1 .

[0056] In some embodiments, see Figure 8 and Fig.10 At least one assembly structure extending along the axial direction of the tube body 1 is provided on the tube body 1, that is, the tube body 1 can be provided with a plurality of assembly structures, wherein there are one or more of the plurality of assembly structures extending along the axial direction of the tube body 1, when the connecting member 3 is pushed to move along the axial direction of the tube body 1 in the assembly structure, the connecting member 3 can drive the temperature measuring member 2 to move along the axial direction of the tube body 1, thereby realizing the position adjustment of the temperature measuring member 2 in the axial direction of the tube body 1, that is, the measuring position of the temperature measuring member 2 in the axial direction of the heating element 100 can be flexibly and quickly adjusted.

[0057] In some embodiments, see Figure 4 and Fig.11 At least one assembly structure extending along the circumference of the tube body 1 is provided on the tube body 1, that is, the tube body 1 can be provided with a plurality of assembly structures, wherein there are one or more of the plurality of assembly structures extending along the circumference of the tube body 1, and when the connecting member 3 is pushed to move along the circumference of the tube body 1 in the assembly structure, the connecting member 3 can drive the temperature measuring member 2 to move along the circumference of the tube body 1, thereby realizing the position adjustment of the temperature measuring member 2 in the circumference of the tube body 1, that is, the measuring position of the temperature measuring member 2 in the circumference of the heating element 100 can be flexibly and quickly adjusted.

[0058] In some embodiments, see Figure 5 and Figure 6 The tube body 1 is provided with at least one assembly structure extending along the axial direction of the tube body 1, and the tube body 1 is also provided with at least one assembly structure extending along the circumferential direction of the tube body 1, that is, the tube body 1 can be provided with multiple assembly structures, wherein one or more of the multiple assembly structures extend along the axial direction of the tube body 1, and one or more extend along the circumferential direction of the tube body 1, so that the measurement position of the temperature measuring component 2 in the axial direction of the heating element 100 can be adjusted, and the measurement position of the temperature measuring component 2 in the circumferential direction of the heating element 100 can be adjusted, and the operation is convenient and fast, and the measurement efficiency is high.

[0059] It can be understood that among the multiple assembly structures, there may be one or more assembly structures extending in both the axial direction and the circumferential direction.

[0060] For further information, see Figure 1 , Figure 2 , Figure 5 and Figure 6 The tube body 1 has a first side and a second side arranged along the circumferential direction. Both the first side and the second side are provided with assembly structures. The assembly structure of the first side extends along the circumference of the tube body 1, and the assembly structure of the second side extends along the axial direction of the tube body 1; each assembly structure is equipped with a connecting piece 3.

[0061] As an example, the tube body 1 can be a quadrangular prism structure with four sides, and the first side and the second side can be two adjacent sides of the tube body 1, or two separated sides, such as two opposite sides. The first side is provided with an assembly structure extending along the circumference of the tube body 1, so that on the first side, the connector 3 can flexibly and quickly adjust the measuring position of the temperature measuring component 2 in the circumferential direction of the heating element 100. The second side is provided with an assembly structure extending along the axial direction of the tube body 1, so that on the second side, the connector 3 can flexibly and quickly adjust the measuring position of the temperature measuring component 2 in the axial direction of the heating element 100. The extension directions of the assembly structures on different sides are different. By moving the connector 3, the measuring points of two adjacent positions in the circumferential direction or axial direction are adjusted, which is convenient for users to obtain the temperature distribution on the heating element 100. In addition, it is also convenient for users to measure and verify the temperature difference between two adjacent measurements in the same area.

[0062] For further information, see Figure 5 and Figure 6 The tube body 1 is provided with a plurality of assembly structures arranged along the axial spacing portion on the first side, and an assembly structure is provided on the second side, wherein the projections of the plurality of assembly structures on the first side along the circumference of the tube body 1 are all located within the axial extension range of the assembly structures on the second side along the tube body 1.

[0063] Specifically, in some embodiments, a plurality of assembly structures extending along the circumference of the tube body 1 are provided on the first side, and the plurality of assembly structures are arranged at intervals along the axial direction of the tube body 1. An assembly structure extending along the axial direction of the tube body 1 is provided on the second side. In the axial direction of the tube body 1, the assembly structure located at the top of the first side will be connected to the top of the assembly structure on the second side if it is extended to the second side; the assembly structure located at the bottom of the first side will be connected to the bottom of the assembly structure on the second side if it is extended to the second side. The assembly structures located in the middle of the first side will be connected to the respective positions in the middle of the assembly structure on the second side if they are respectively extended to the second side. Therefore, in the axial direction of the tube body 1, by measuring the positions on different sides of the heating element 100 but at the same horizontal height, the temperature difference between the positions on different sides of the heating element 100 at the same horizontal height can be checked, and the temperature distribution on the heating element 100 can be obtained.

[0064] It should be noted that, in some embodiments, the tube body 1 has a plurality of first sides and second sides along the circumferential direction. Specifically, the first side and the second side are alternately arranged along the circumferential direction of the tube body 1 .

The temperature measuring head 21 can protrude from the inner side of the tube body 1, or it can protrude from the outer side of the tube body 1.

[0067] In some embodiments, see Figure 8 and Fig.10 The connecting members 3 are all movably connected to the mounting grooves 11, one mounting groove 11 corresponds to one connecting member 3, and by moving the connecting member 3 to different positions on the mounting grooves 11, the temperature measuring member 2 can measure different positions of the heating element 100.

One mounting slot 11 may correspond to one connecting member 3, or one connecting member 3 may be installed in different mounting slots 11. First, the connecting member 3 is moved to the target position of the mounting slot 11, and then the connecting member 3 is detachably assembled and connected to the mounting slot 11.

[0069] In some embodiments, see Figure 5 and Figure 6 Part of the mounting groove 11 is movably connected to the connecting member 3, and part of the mounting groove 11 is connected to the connecting member 3 in a manner that is both movably connected and detachably assembled.

[0073] Specifically, in some embodiments, for the same mounting slot 11, a limiting slot 12 extending along the extension direction of the mounting slot 11 is provided on the outside of the mounting slot 11. In some achievable embodiments, the connecting portion 30 is movably connected to the limiting slot 12. When the movable connecting portion 30 is at different positions of the limiting slot 12, the connecting member 3 can be fixed at different positions of the mounting slot 11, and then the temperature measuring member 2 can measure different positions of the heating element 100. In some achievable embodiments, the connecting portion 30 is both movably connected to the limiting slot 12 and detachably connected to the limiting slot 12. Similarly, the temperature measuring member 2 can measure different positions of the heating element 100.

[0077] For further information, see Figure 2-4 , Figure 8 and Fig. 9 The connecting part 30 is provided with an assembly hole; each connecting part 30 is also provided with a first fixing part 4, one end of the first fixing part 4 is located outside the assembly hole, and the other end of the first fixing part 4 is passed through the assembly hole and is removably fixed in the limiting groove 12, or, the other end of the first fixing part 4 is sequentially passed through the assembly hole, the limiting groove 12 to the tube body 1 and is removably connected with the second fixing part 5.

[0078] In some embodiments, the connection between the connecting portion 30 and the limiting groove 12 is a detachable connection. In some achievable embodiments, the first fixing member 4 is a screw, and the inner wall of the limiting groove 12 is provided with an internal thread, and the screw and the internal thread are matched and connected. In the radial direction of the tube body 1, there are an assembly hole of the connecting portion 30 and a limiting groove 12 of the tube body 1 in sequence, and the first fixing member 4 passes through the assembly hole and the limiting groove 12 in sequence. During assembly, first align the assembly hole of the connecting portion 30 with the limiting groove 12 of the tube body 1, then pass the screw through the assembly hole, and screw it into the limiting groove 12. At this time, the connecting portion 30 will be fixed between the screw and the tube body 1, so that the radial direction of the connecting member 3 can be limited to the tube body 1, and the connecting member 3 is prevented from being separated from the tube body 1.

[0079] In some other possible implementations, the first fixing member 4 may be a screw with a part of the thread, and the second fixing member 5 may be a nut. In the radial direction of the tube body 1, there are the assembly hole of the connection part 30, the limiting groove 12 of the tube body 1 and the nut in sequence, and the first fixing member 4 passes through the assembly hole, the limiting groove 12 and the nut in sequence. During assembly, the assembly hole of the connection part 30 is first aligned with the limiting groove 12 of the tube body 1, and then the first fixing member 4 is passed through the assembly hole and the limiting groove 12 in sequence, wherein the outer peripheral side of the part of the first fixing member 4 without the thread is abutted against the hole wall of the assembly hole, and the part of the first fixing member 4 with the thread will pass through the assembly hole and the limiting groove 12 in sequence, and protrude from the side of the tube body 1 away from the connection part 30, the nut is placed on the side of the tube body 1 away from the connection part 30, and the nut and the part of the first fixing member 4 with the thread are threadedly connected, and the nut will abut against the side of the tube body 1 away from the connection part 30. At this time, the connecting portion 30 and the tube body 1 are fixed between the first fixing member 4 and the second fixing member 5, so that the connecting member 3 can be limited in the radial direction of the tube body 1 to prevent the connecting member 3 from being separated from the tube body 1.

[0080] In some embodiments, the connection between the connecting portion 30 and the limiting groove 12 is both a detachable connection and a movable connection. Similarly, in some implementable embodiments, only the first fixing member 4 may be included. When the connecting member 3 moves to a specific position of the tube body 1, the first fixing member 4 can limit the radial direction of the connecting member 3 of the tube body 1 to prevent the connecting member 3 from being separated from the tube body 1. In some other implementable embodiments, the first fixing member 4 and the second fixing member 5 may be included. When the connecting member 3 moves to a specific position of the tube body 1, the locking of the connecting member 3 at the specific position of the tube body 1 can be achieved through the assembly relationship between the connecting portion 30 and the limiting groove 12.

[0081] For further information, see Figure 6 and Figure 7 A limiting flange 13 is provided in the installation groove 11 , and / or a limiting flange 13 is provided in the limiting groove 12 , and the limiting flange 13 is used to provide damping for the connection member 3 to move along the extending direction of the installation groove 11 .

[0082] Specifically, in some embodiments, the pipe body 1 is provided with a mounting groove 11 extending in the axial direction or the circumferential direction, and the limiting flange 13 is provided in the mounting groove 11. When the connecting member 3 is located in the mounting groove 11, if it is not acted upon by an external force, the connecting member 3 can be locked at a specific position in the mounting groove 11 under the blocking effect of the limiting flange 13. The connecting member 3 can move in the mounting groove 11 only when the external force overcomes the damping force of the limiting flange 13.

[0083] In some embodiments, a limiting groove 12 extending in the axial direction or the circumferential direction is further provided on the tube body 1 , and the limiting flange 13 can be disposed in the limiting groove 12 .

[0084] In some embodiments, both the mounting groove 11 and the limiting groove 12 may be provided with a limiting flange 13 .

[0085] For further information, see Figure 1-11 The tube body 1 is formed with a receiving cavity for receiving the heating element 100, and the temperature measuring head 21 protrudes from the receiving cavity.

[0086] Specifically, in some embodiments, the temperature measuring element 2 is assembled on the pipe body 1, and after the temperature measuring element 2 is fixed / locked at a specific position on the pipe body 1, the temperature measuring head 21 protrudes from the accommodating cavity. The heating element 100 can be directly inserted into the accommodating cavity, and the heating element 100 can contact the temperature measuring head 21, so that the temperature measuring element 2 can measure the temperature of the heating element 100 at the contact position.

[0087] For further information, see Figure 8 and Fig. 9 The temperature measuring head 21 can be telescopically movable along the radial direction of the accommodating cavity.

[0088] Specifically, in some embodiments, the temperature measuring component 2 is assembled on the tube body 1. After the temperature measuring component 2 is fixed / locked at a specific position on the tube body 1, the temperature measuring head 21 can be telescopically moved along the radial direction of the accommodating cavity. In practical applications, when the heating element 100 is assembled in the accommodating cavity, the heating element 100 may not be directly in contact with the temperature measuring head 21. There may be a gap between the temperature measuring head 21 and the heating element 100 in the radial direction of the accommodating cavity, or the axial projection of the heating element 100 may cover the temperature measuring head 21. Therefore, the temperature measuring head 21 can be radially telescopically moved according to the different sizes of the heating element 100. Finally, the temperature measuring head 21 is in contact with the heating element 100 to achieve accurate measurement of the temperature at the contact position of the heating element 100. The temperature measuring device can be applicable to heating elements 100 of different sizes and has a wide range of applications.

[0089] For further information, see Figure 8 and Fig. 9 The connecting member 3 includes a shell 31, an elastic member 34 arranged in the shell 31, and a first cover body 32 with one end movably arranged in the shell 31 and abutting against the elastic member 34. The shell 31 is penetrated in the assembly structure; the temperature measuring member 2 is penetrated in the shell 31 and the first cover body 32, and the temperature measuring head 21 is abutted against the other end of the first cover body 32.

[0090] Specifically, in some embodiments, the housing 31 extends radially along the tube body 1, the housing 31 is disposed in the assembly structure, and the first cover 32 is movably connected to the housing 31, that is, the first cover 32 can move radially along the tube body 1. The temperature measuring head 21 is fixed to the first cover 32, so the first cover 32 can drive the temperature measuring head 21 to move radially along the tube body 1, thereby realizing the radial telescopic movement of the connector 3. The elastic member 34 can be a spring, and the elastic member 34 is mainly used to provide a restoring force to move the first cover 32 into the accommodating cavity.

[0091] When there is a gap between the temperature measuring head 21 and the heating element 100 in the radial direction of the accommodation cavity, the elastic member 34 pushes the first cover 32 to move into the accommodation cavity, and the first cover 32 drives the temperature measuring head 21 to move in the same direction, and the temperature measuring head 21 can contact and fit the heating element 100. When the axial projection of the heating element 100 covers the temperature measuring head 21, the heating element 100 pushes the first cover 32 to move out of the accommodation cavity, the elastic member 34 is compressed, and the heating element 100 smoothly penetrates into the accommodation cavity and contacts and fits with the temperature measuring head 21.

[0092] For further information, see Figure 8 and Fig. 9 The connecting member 3 also includes a second cover body 33 fixed to an end of the shell 31 away from the first cover body 32 and abutting against the elastic member 34, and a connecting portion 30 is provided on the second cover body 33; the assembly structure includes an installation groove 11 and a limiting groove 12 corresponding to the installation groove 11; the shell 31 is penetrated into the installation groove 11, and the connecting portion 30 is at least partially penetrated into the limiting groove 12.

[0093] Specifically, in some embodiments, the second cover 33 is fixedly connected to the housing 31, and the elastic member 34 abuts between the first cover 32 and the second cover 33. After the connector 3 is fixed / locked at a specific position on the tube 1, the elastic member 34 can drive the first cover 32 to move radially in the same direction. Further, the connecting portion 30 is arranged on the second cover 33, the connecting portion 30 corresponds to the limiting groove 12, and the housing 31 corresponds to the mounting groove 11. When the connector 3 moves on the tube 1, the connecting portion 30 is arranged on different limiting grooves 12 or at different positions of the limiting groove 12, and at the same time, the housing 31, the first cover 32, the elastic member 34, etc. will move in the same direction, and be arranged in different mounting grooves 11 or at different positions of the mounting groove 11. Therefore, it is possible to measure different positions of the heating element 100, and it is also possible to achieve the application of heating elements 100 of different sizes through the radial expansion and contraction of the connector 3 after the connector 3 is fixed / locked at a specific position on the tube 1.

[0094] Furthermore, the tube body 1 can be made of a metal material with low thermal conductivity, and the thermal conductivity coefficient can be less than 100W / (m·K), for example, it can be stainless steel 304, etc.; the first fixing member 4 and the second fixing member 5 can be a low thermal conductivity metal or a plastic with a temperature resistance of about 300°C, such as PEEK (polyetheretherketone); the connecting member 3 can be made of metal material; the temperature measuring member 2 can be a thermocouple, and the model of the thermocouple can be K type, S type, T type, etc.

[0095] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0096] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
