Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, and in particular to a fixing structure and an aerosol generating device. Background Art

[0002] One type of aerosol generating device generally heats a liquid or paste-like substance, such as medicine or tobacco liquid, into atomized form to emit an aerosol or mist for the user. Another type of aerosol generating device heats the aerosol generating product through a heating component.

[0003] The heating element on the heating assembly uses a thermocouple to detect temperature. Currently, thermocouples are primarily secured using high-temperature tape or direct welding. High-temperature tape can easily loosen the thermocouple, causing it to detach from the heating element, ultimately leading to temperature control errors. Manual welding of thermocouples to the heating element results in poor consistency, resulting in inconsistent solder joint sizes between different heating elements, making it difficult to manufacture in large quantities.

[0037] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] Example 1:

[0040] like Figures 1-4 As shown, this embodiment provides an aerosol generating device, comprising a heating assembly and a battery, wherein the battery is electrically connected to the heating assembly and is used to power the heating assembly. The heating assembly comprises a heating element 200, a mounting base 100, and a temperature measuring element 400. The heating element 200 is mounted within the mounting base 100. The heating element 200 is provided with an electrode 201, which is connected to the battery to enable the heating element 200 to generate heat. The heating element 200 encloses a receiving cavity, and the aerosol generating article 300 is at least partially positioned within the receiving cavity. When the heating element 200 is energized, it generates heat to heat the aerosol generating article 300, which is a substrate capable of releasing volatile compounds that can form an aerosol. The temperature measuring element 400 includes, but is not limited to, a thermocouple. The temperature measuring element 400 is fixed to the heating element 200 via a fixing structure and is used to detect the temperature of the heating element 200 to control the temperature of the aerosol generated by the aerosol generating article 300. The heating element 200 is provided with a temperature measuring point, and the temperature measuring end 401 of the temperature measuring element 400 abuts against the temperature measuring point to measure the temperature of the heating element 200. The temperature measuring point on the heating element 200 is a position selected through experiments to have a temperature closest to the average temperature of the heating element 200.

[0041] The aerosol generating product 300 is a cigarette, which includes a flat cigarette and a round cigarette. The heating element 200 for heating the flat cigarette is a sheet-type heating element, and the heating element 200 for heating the round cigarette is a cylindrical heating element. Figure 3 As shown, the heating element 200 of the aerosol generating device provided in this embodiment is a sheet-type heating element, used to heat flat cigarettes. Two sheet-type heating elements are positioned opposite each other within the mounting cavity, with the flat cigarette at least partially sandwiched between the two sheet-type heating elements. A temperature measuring element 400 is affixed to the opposite sides of the two sheet-type heating elements.

[0042] In order to ensure the accuracy of the temperature measurement element 400 in detecting the temperature of the heating element 200, thereby accurately controlling the heating temperature of the flat cigarette, this embodiment also provides a fixing structure, which is applied to the above-mentioned aerosol generating device. The fixing structure includes a fixing member 1, each end of the fixing member 1 is provided with a clamping portion 11, and the middle portion is provided with a fixing portion 12. The temperature measuring end 401 of the temperature measuring element 400 is aligned with the temperature measuring point, and the fixing portion 12 is aligned with the temperature measuring end 401. After the clamping portion 11 is clamped and fixed to both sides of the temperature measuring point of the heating element 200, the temperature measuring end 401 can be clamped between the temperature measuring point and the fixing portion 12, ensuring the reliability of the connection between the temperature measuring end 401 of the temperature measuring element 400 and the temperature measuring point of the heating element 200, preventing the temperature measuring end 401 from being separated from the temperature measuring point and affecting the accuracy of the measured temperature, and can effectively measure the temperature of the heating element 200. In addition, the fixing member 1 has a simple structure, is easy to process and manufacture, and can be mass-produced; and is also relatively low in cost.

[0043] Furthermore, the chip heating element is arranged in the mounting base 100, and the mounting base 100 is provided with a hollow shape on opposite sides for installing the two chip heating elements, so that the two ends of the fixing member 1 are respectively clamped with the support columns 101 of the mounting base 100 at both ends of the chip heating element, and a clamping groove is provided on the support column 101, and the clamping portion 11 is clamped with the clamping groove, so that the fixing member 1 is fixed on the mounting base 100, and a limited surface 102 is provided in the mounting base 100. After the two ends of the fixing member 1 are clamped with the support column 101, the fixing portion 12 presses the temperature measuring end 401 against the temperature measuring point while pressing the chip heating element against the limiting surface 102, thereby limiting the relative displacement and deformation of the chip heating element.

[0044] In one embodiment, since a relatively high temperature is required to heat the aerosol-generating product 300 to generate aerosol after the heating element 200 is powered on, in order to prevent the fixing part 1 from being deformed by heat and affecting the fixation of the temperature measuring element 400, the fixing part 1 is made of a material with relatively high heat resistance and certain elasticity, such as PEEK (polyetheretherketone), PC (polycarbonate), etc.

[0045] In one embodiment, the fixing structure further includes an elastic abutment 2, which is provided on the fixing portion 12 and is used to abut against the temperature measuring end 401. By providing the elastic abutment 2 on the fixing portion 12 and abutting against the temperature measuring end 401, elastic fixation of the temperature measuring element 400 is achieved, so that the fixing member 1 can fix the temperature measuring element 400 without damaging the sheet-type heating element.

[0046] Specifically, the elastic abutment 2 includes aerogel or silica gel. Aerogel has the characteristics of high elasticity and strong adsorption. It is provided in the fixing portion 12, which can ensure effective contact between the temperature measuring end 401 and the temperature measuring point, and can buffer the pressing force of the fixing member 1 on the heating element 200 to avoid damage to the sheet heating element. In addition, aerogel also has a good heat insulation effect, which can prevent the fixing member 1 from directly contacting the temperature measuring end 401 and being deformed by the high temperature of the heating element 200, thereby affecting the fixation of the temperature measuring element 400. Silica gel also has the characteristics of high temperature resistance, stable adhesion, and good durability, which can ensure the reliability of the fixation of the temperature measuring element 400.

[0047] Furthermore, the fixing portion 12 includes a fixing groove 121, and the elastic abutment member 2 is disposed in the fixing groove 121. Placing the aerogel or silica gel in the fixing groove 121 prevents the aerogel or silica gel from shifting and failing to abut against the temperature measuring end 401 accurately.

[0048] like Figure 5 and Figure 6 As shown, in this embodiment, according to the structure and coordination of the sheet heating element and the mounting base 100, the fixing member 1 is set as a U-shaped body, and the fixing groove 121 is set in the middle of the bottom surface of the U-shaped body; both ends of the opening of the U-shaped body are provided with a limiting arm 111 extending inward, and a clamping portion 11 is formed between the limiting arm 111 and the bottom surface of the U-shaped body. When the temperature measuring element 400 is fixed to the U-shaped body, the aerogel or silica gel is first placed in the fixing groove 121, and the temperature measuring end 401 of the temperature measuring element 400 is aligned with the temperature measuring point on the sheet heating element, and then the aerogel or silica gel is aligned with the temperature measuring end 401, and the clamping portion 11 is placed in the clamping groove of the support column 101 on both sides of the sheet heating element, and the inner side of the limiting arm 111 is abutted against the side of the support column 101, so that the fixing member 1 is fixed on the support column 101 while the aerogel or silica gel presses the temperature measuring end 401 against the temperature measuring point.

[0049] Furthermore, the fixing portion 12 also includes two abutting arms 122, which are provided on the bottom surface of the U-shaped body. The two abutting arms 122 are respectively located on either side of the fixing groove 121, and one end of the abutting arm 122 away from the bottom surface of the U-shaped body abuts against the heating element 200. The provision of the two abutting arms 122 can limit the deviation caused by the left and right movement of the temperature measuring end 401, further ensuring the reliability of the contact between the temperature measuring end 401 and the temperature measuring point.

[0050] The fixing member 1 provided in this embodiment has a simple structure, a mature preparation process, is easy to produce, and has good mass production feasibility. Moreover, the fixing member 1 is small in size. Figure 4 As shown, the fixing member 1 is located between the two electrodes 201 , leaving enough tolerance space for welding the electrodes 201 and the heating element 200 .

[0051] Example 2:

[0052] like Figure 7-10 As shown, this embodiment provides an aerosol generating device, wherein the heating element 200 is a cylindrical heating element for heating round cigarettes.

[0053] According to the structural characteristics of the cylindrical heating element, this embodiment further provides a fixing structure of a temperature measuring element 400 suitable for the cylindrical heating element.

[0054] The fixing structure provided in this embodiment is a modified improvement of the fixing structure provided in the first embodiment, in which the fixing member 1 is set as a semi-annular body, the fixing groove 121 is set in the middle of the semi-annular body, and two clamping parts 11 are formed on both sides of the fixing groove 121. The inner diameter of the two clamping parts 11 is adapted to the outer diameter of the cylindrical heating element, so that the clamping parts 11 can be effectively clamped with the outer periphery of the cylindrical heating element. The elastic abutment 2 and the temperature measuring end 401 of the temperature measuring element 400 are both placed in the fixing groove 121. The fixing groove 121 plays a limiting role on the elastic abutment 2 and the temperature measuring end 401, so as to ensure the effective abutment of the temperature measuring end 401 with the temperature measuring point, thereby ensuring the accuracy of the temperature measurement of the temperature measuring element 400.

[0055] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
