[0001] The present application relates to the technical field of aerosol generation, in particular to a temperature detection assembly of a heat-not-burn device and the heat-not-burn device. BACKGROUND

[0002] The heat-not-burn device is a device that heats an aerosol substrate to make the aerosol substrate generate an aerosol.

However, when the position of the temperature sensor detecting the heating body is different or the temperature sensor is not in good contact with the heating body, the temperature measured by the temperature sensor has a large deviation, which leads to inaccurate measurement and further makes it difficult to realize the precise temperature control of the heat-not-burn device.

[0008] In one embodiment, a through groove is provided on the main body, and the groove wall of the through groove has a first wall, a second wall, a third wall and a fourth wall connected in sequence, the first wall of the through groove is connected to the first connecting portion, the third wall of the through groove is connected to the second connecting portion, and the spring portion is spaced apart from the second wall and the fourth wall.

[0009] In one embodiment, there are multiple spring fragments; the multiple spring fragments are arranged along the circumferential direction of the heat-conducting element, or the multiple spring fragments are arranged along the axial direction of the heat-conducting element, or, among the multiple spring fragments, some of the spring fragments are arranged along the circumferential direction of the heat-conducting element, and the other part of the spring fragments are arranged along the axial direction of the heat-conducting element.

[0010] In one embodiment, the contact surface is in the shape of an arc, and the long side of the arc extends along the axial direction or the circumferential direction of the heat conducting element;

[0011] Alternatively, the contact surface is in the shape of a ring, and the ring extends along the circumference of the heat conducting element.

[0012] In one embodiment, the elastic fragment portion is made of aluminum alloy or copper, or the thermal conductivity of the elastic fragment portion is greater than or equal to 50 W / (m·K).

[0013] In one embodiment, the temperature detection assembly of the heat-not-burn device further includes a handpiece connected to the heat-conducting element;

The spring sheet part can elastically deform to generate an elastic force when it is in contact with the heat-generating body. The elastic force can make the contact surface abut against the heat-generating body when they are in contact, so that they are in close contact. This can prevent the problem of inaccurate measurement caused by poor contact between the temperature detection assembly and the heat-generating body. BRIEF DESCRIPTION OF DRAWINGS

[0030] Please refer to Figures 1-3 The present application provides a temperature detection assembly 10 of a heat-not-burn device, which comprises a heat-conducting element 11 and a temperature sensor 12. The heat-conducting element 11 has a spring sheet portion 111, and the spring sheet portion 111 has a contact surface 112. Specifically, the spring sheet portion 111 is in the shape of a sheet, and along the thickness direction of the spring sheet portion 111, the spring sheet portion 111 has two opposite surfaces, one of which is the contact surface 112. The contact surface 112 is used to be in surface contact with a heating body 30 of the heat-not-burn device. The spring sheet portion 111 is used to elastically deform when in contact with the heating body 30 to generate an elastic force, and the elastic force can make the contact surface 112 abut against the heating body 30, so that the heating body 30 and the spring sheet portion 111 are in close contact.

[0031] The temperature sensor 12 is fixed to the heat-conducting element 11, and the way in which the temperature sensor 12 is fixed to the heat-conducting element 11 is not limited, for example, the temperature sensor 12 can be fixed to the heat-conducting element 11 by welding. The temperature sensor 12 is in contact with the heat-conducting element 11, so that the temperature sensor 12 can detect the temperature of the heat-conducting element 11.

[0032] Specifically, in an embodiment, the temperature sensor 12 comprises a temperature-sensing probe for sensing temperature and a conductive lead connected to the temperature-sensing probe. The temperature-sensing probe is used to sense temperature to generate a sensing signal, and the conductive lead can be electrically connected to a data collection instrument to transmit the sensing signal to the data collection instrument, and the data collection instrument can display the temperature measurement result when sensing the sensing signal. Generally, the number of conductive leads is two, one is a positive lead and the other is a negative lead.

[0033] Preferably, the temperature sensor 12 is a thermocouple. In other embodiments, the temperature sensor 12 can also be a thermistor type temperature sensor 12.

[0034] The spring part 111 of the heat-conducting element 11 of the present application can replace the existing temperature sensor to directly contact the heating element 30. Since the spring part 111 and the heating element 30 are in surface contact, the spring part 111 can turn the position where the temperature detection component 10 contacts the heating element 30 into a temperature zone. The spring part 111 has a certain area, which can make the temperature transferred from the heating element 30 to the spring part 111 uniform. Therefore, the temperature sensor 12 fixed on the heat-conducting element 11 is equivalent to detecting the average temperature of the heating element 30. Therefore, compared with only measuring the temperature of individual temperature points, the temperature detection component 10 of the present application has a small measurement deviation and is more accurate. And since the temperature sensor 12 is fixed on the heat-conducting element 11 to detect the temperature of the heat-conducting element 11, the temperature sensor 12 is not in direct contact with the heating element 30, which avoids the problem of inaccurate measurement caused by different degrees of contact between the temperature sensor 12 and the heating element 30. The spring portion 111 can elastically deform and generate elastic force when in contact with the heating element 30. The elastic force can keep the contact surface 112 in contact with the heating element 30 so that the two are in close contact, thereby preventing the temperature detection component 10 from having poor contact with the heating element 30 and causing inaccurate measurements.

[0035] To ensure the accuracy of temperature sensor 12 measurements, thermal element 11 can be made of a material with high thermal conductivity. High thermal conductivity refers to a thermal conductivity greater than or equal to 50 W / (m·K). Specifically, thermal element 11 can be made of a high-thermal-conductivity metal, such as aluminum alloy or copper. By configuring thermal element 11 with high thermal conductivity, heat loss during heat conduction can be minimized, thereby improving the accuracy of temperature sensor 12 measurements.

[0036] In one embodiment, if Figures 1-4 As shown, the heat-conducting element 11 has a tubular structure and defines a housing cavity 113 therein. The housing cavity 113 has an opening 114 at at least one of its two ends along the axial direction of the heat-conducting element 11. The opening 114 is used to allow the heating element 30 to be inserted into and removed from the housing cavity 113. Preferably, both ends of the housing cavity 113 have openings 114, with the opening 114 at one end allowing the heating element 30 to be inserted into and removed from the housing cavity 113, and the opening 114 at the other end allowing the temperature sensor 12 to pass through, thereby allowing the temperature sensor 12 to be disposed within the housing cavity 113. Of course, in other embodiments, the temperature sensor 12 may also be disposed outside the housing cavity 113.

[0037] Specifically, if Figure 4As shown, the side wall of the heat-conducting element 11 comprises a main body part 115 and a spring part 111 connected to each other, the spring part 111 is recessed relative to the main body part 115 towards the axis of the heat-conducting element 11, that is, the spring part 111 is recessed inwardly relative to the main body part 115, and the side of the spring part 111 towards the axis of the heat-conducting element 11 has a contact surface 112, that is, the inner side of the spring part 111 has the contact surface 112. By recessing the spring part 111 inwardly relative to the main body part 115, when the heat-generating body 30 is inserted into the accommodating cavity 113, the contact surface 112 on the inner side of the spring part 111 can abut against the heat-generating body 30 in the accommodating cavity 113, the heat-generating body 30 presses the spring part 111, so that the spring part 111 generates an elastic force to make the spring part 111 and the heat-generating body 30 tightly contact, preventing poor contact between the spring part 111 and the heat-generating body 30 from affecting heat conduction.

[0038] Further, as shown, Figure 4 The spring part 111 has a first connecting part 116, a second connecting part 117 and a contact part 118, one end of the contact part 118 is connected to the first connecting part 116, the other end of the contact part 118 is connected to the second connecting part 117, the first connecting part 116 and the second connecting part 117 are connected to the main body part 115, the first connecting part 116 and the second connecting part 117 are in a bent structure, the first connecting part 116 and the second connecting part 117 are bent relative to the main body part 115 towards the axis of the heat-conducting element 11, and the surface of the contact part 118 close to the axis of the heat-conducting element 11 is the contact surface 112. Through the above structure, the contact surface 112 can match the shape of part of the heat-generating body 30, and the first connecting part 116 and the second connecting part 117 are bent to realize that the contact part 118 can have the ability of elastic deformation.

[0039] In an embodiment, a through groove 1151 is formed on the main body part 115, the groove wall of the through groove 1151 has a first wall 1152, a second wall 1153, a third wall 1154 and a fourth wall 1155, the first wall 1152, the second wall 1153, the third wall 1154 and the fourth wall 1155 enclose the through groove 1151, the first wall 1152 and the third wall 1154 are oppositely arranged, the second wall 1153 and the fourth wall 1155 are oppositely arranged, the first wall 1152 of the through groove 1151 is connected to the first connecting part 116, the third wall 1154 of the through groove 1151 is connected to the second connecting part 117, and the spring part 111 is spaced apart from the second wall 1153 and the fourth wall 1155. Thus, the spring part 111 is connected only to the first wall 1152 and the third wall 1154, and is separated from the second wall 1153 and the fourth wall 1155, which can increase the elastic force of the contact part 118, and when the contact part 118 is made of a relatively hard material, the contact part 118 can also generate a large elastic force to abut against the heat-generating body 30 when abutting against the heat-generating body 30.

[0040] In an embodiment, as shown in Figure 4 the contact surface 112 is arc-shaped, and the long side of the arc-shaped contact surface 112 extends along the axial direction or the circumferential direction of the heat-conducting element 11, i.e., the contact portion 118 is arc-shaped, and the long side of the contact portion 118 extends along the axial direction or the circumferential direction of the heat-conducting element 11. Similarly, the long side of the through groove 1151 is consistent with the extension direction of the long side of the contact portion 118. Alternatively, the contact surface 112 is ring-shaped, and the ring-shaped contact surface 112 extends along the circumferential direction of the heat-conducting element 11. When the heat-generating body 30 is a needle-type heat-generating body, the high-temperature zone of the heat-generating body 30 is located at the cylindrical portion of the needle-type heat-generating body, and the contact portion 118 needs to be in contact with the outer surface of the cylindrical portion of the needle-type heat-generating body. Therefore, the contact portion 118 is arc-shaped or ring-shaped, which facilitates the surface contact between the contact portion 118 and the outer surface of the cylindrical portion of the needle-type heat-generating body. When the contact surface 112 extends along the axial direction, the average temperature of the heat-generating body 30 in the vertical direction can be measured. When the contact surface 112 extends along the circumferential direction, the average temperature of the heat-generating body 30 in the circumferential direction can be measured.

[0041] In an embodiment, as shown in Figures 1-3 the plurality of spring sheet portions 111 are arranged along the circumferential direction of the heat-conducting element 11, or the plurality of spring sheet portions 111 are arranged along the axial direction of the heat-conducting element 11, or part of the plurality of spring sheet portions 111 are arranged along the circumferential direction of the heat-conducting element 11, and the other part of the plurality of spring sheet portions 111 are arranged along the axial direction of the heat-conducting element 11. By arranging the plurality of spring sheet portions 111, the heat-conducting element 11 can have a plurality of temperature detection zones, and the temperature of the heat-generating body 30 can be transmitted to the spring sheet portions 111 from different positions, thereby making the average temperature test result of the heat-generating body 30 more accurate.

[0042] In an embodiment, as shown in Figure 5 the temperature detection assembly 10 of the heat-not-burn device further comprises a handpiece 13 connected with the heat-conducting element 11. The handpiece 13 can be detachably connected with the heat-conducting element 11, or the handpiece 13 can be fixedly connected with the heat-conducting element 11. For example, in the embodiments of Figure 4 and Figure 5 the handpiece 13 is snap-connected with the heat-conducting element 11. By arranging the handpiece 13, the user can hold the handpiece 13 to facilitate the insertion of the heat-conducting element 11 into the heat-not-burn device. The material of the handpiece 13 can be a temperature-resistant and low-thermal-conductivity material, so as to prevent the heat-conducting element 11 from transmitting heat to the handpiece 13 as much as possible, thereby making the temperature measurement result more accurate and effectively preventing the user from being scalded. The temperature-resistant and low-thermal-conductivity material can be temperature-resistant plastic or ceramic. The low-thermal-conductivity material can be a material with a thermal conductivity lower than 5 W / (m·K).

[0043] The interior of the handpiece 13 has a through cavity 131, and the temperature sensor 12 passes through the through cavity 131, so that the temperature sensor 12 can be arranged inside the heat-conducting element 11. The handpiece 13 can be provided with a limiting portion 132, and the limiting portion 132 extends along the radial direction of the handpiece. The limiting portion 132 is used to abut against the heat-not-burn device to limit the heat-conducting element 11. Specifically, the side of the limiting portion 132 close to the heat-conducting element 11 is used to abut against the heat-not-burn device, so that when the temperature detection component 10 is inserted into the heat-not-burn device, the limiting portion 132 limits the insertion depth of the temperature detection component 10.

[0044] In order to solve the above technical problems, Figures 6-7 As shown, the present application also provides a heat-not-burn device, which includes a shell assembly 20, a heating element 30 and a temperature detection assembly 10. An installation cavity 221 is provided in the shell assembly 20. Specifically, the shell assembly 20 may include an outer shell 21 and a cup body 22, the cup body 22 is installed inside the outer shell 21, and the interior of the cup body 22 forms an installation cavity 221, at least a portion of the heating element 30 is provided in the installation cavity 221, and the heating element 30 is used to contact the aerosol matrix so that the aerosol matrix generates an aerosol. The temperature detection assembly 10 can be the temperature detection assembly 10 of the heat-not-burn device involved in any of the above-mentioned embodiments, and the heat-not-burn device can have the same technical effect as the above-mentioned temperature detection assembly 10.

[0045] One end of the mounting cavity 221 has a socket 222 for inserting and removing the aerosol matrix and the heat-conducting element 11 from the mounting cavity 221. The heating element 30 can be disposed on a side of the mounting cavity 221 away from the socket 222. In one embodiment, the heating element 30 is a pin-type heating element that can be inserted into the interior of the heat-conducting element 11. The spring portion 111 has an elastic force that enables the contact surface 112 to be in close contact with the pin-type heating element.

[0046] The above examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, modifications or substitutions can be made based on the ideas of the present invention.
