Detailed implementation manners

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0032] In existing atomization devices, the thermocouple probe is in a point - contact state with the electrical heating wire 40. Without the aid of other materials for fixation, it is difficult to fix the thermocouple probe on the surface of the heating wire.

[0033] The contact area between the thermocouple probe and the heating wire is relatively small. Especially in miniaturized atomization devices, the size of the thermocouple probe is larger than that of the electrical heating wire 40, making it more difficult to closely contact the electrical heating wire 40. The farther away from the surface of the heating wire, the lower the air flow temperature, and the low - temperature air flow will cause the measured temperature to be on the low side.

[0034] In the embodiment of the present invention, the temperature measurement component 3 formed by connecting multiple thermocouple structures 30 in parallel can increase the temperature measurement points and the contact area with the electric heating wire 40, thereby improving the temperature measurement accuracy of the electric heating wire 40.

[0035] Embodiment 1:

[0036] Please refer to Figure 1 and Figure 2 , this embodiment provides a temperature measurement device, which includes a positive output terminal 1, a negative output terminal 2, and a temperature measurement component 3.

[0037] The positive output terminal 1 and the negative output terminal 2 are respectively connected to the specified input ports, and the first voltage between the positive output terminal 1 and the negative output terminal 2 is obtained through an external terminal device, and the temperature is calculated based on the first voltage.

[0038] The temperature measurement component 3 may include multiple thermocouple structures 30 connected in parallel. The thermocouple structure 30 may include a first positive electrode metal 31 and a first negative electrode metal 32. The first positive electrode metal 31 and the first negative electrode metal 32 of one thermocouple structure 30 are electrically connected, and the electrical connection point 33 of the first positive electrode metal 31 and the first negative electrode metal 32 corresponds to the temperature measurement point of the thermocouple structure 30; the first positive electrode metal 31 of each thermocouple structure 30 is electrically connected to the positive output terminal 1, and the first negative electrode metal 32 of each thermocouple structure 30 is electrically connected to the negative output terminal 2.

[0039] As Figure 2 shown, each thermocouple structure 30 can be equivalent to a voltage source controlled by temperature and a resistor. Assuming that the temperature measurement component 3 includes four thermocouple structures 30, Figure 1 the temperature measurement device shown can be equivalent to Figure 2 the circuit shown.

[0040] Thus, the voltage E between the positive output terminal 1 and the negative output terminal 2 can be obtained as shown in the following formula 1:

[0041]

[0042] where, I total is the current between the positive output terminal 1 and the negative output terminal 2, R equal is the total resistance between the positive output terminal 1 and the negative output terminal 2, E1 to E4 are the thermoelectric potentials generated by the thermocouple structure 30, and R1 to R4 are the resistances of the thermocouple structure 30.

[0043] When the resistances between each thermocouple structure 30 are the same, the above formula 1 can be obtained as the following formula 2:

[0044]

[0045] It can be seen that according to the circuit equivalent principle, when the resistances of the thermocouple structures 30 are the same, the output thermoelectromotive force E of multiple parallel thermocouple structures 30 is the average value of the thermoelectromotive forces of each thermocouple structure 30, that is, the average value of the measurement values of multiple thermocouple structures 30; when the resistances of the thermocouple structures 30 are different, the output thermoelectromotive force E of multiple parallel thermocouple structures 30 is between the thermoelectromotive forces of the minimum and maximum thermocouple structures 30, that is, the measured temperature is between the minimum and maximum values of the measurement values of multiple thermocouples.

[0046] It can be seen that if only one thermocouple probe is used for measurement, the error between the measured temperature T0 and the temperature Tmax of the electric heating wire 40 is obviously uncontrollable and impossible to predict; while in this application, through multiple thermocouple components (assuming the same resistance), for each thermocouple structure 30, T1, T2, T3 and T4 can be measured. Then the measured temperature T is actually jointly determined by T1, T2, T3 and T4, avoiding the large measurement error of a single thermocouple.

[0047] In practical applications, in order to further improve the accuracy of temperature measurement, this application proposes a method and structure for fixing the temperature measurement component 3 to the electric heating wire 40 to increase the contact surface. When the temperature measurement device provided in this embodiment is actually used, as Figure 3 shown, the temperature measurement component 3 is integrally strip-shaped, so that the temperature measurement component 3 can be wound or coiled around the outer periphery of the electric heating wire 40 to make the temperature measurement point of the temperature measurement component 3 contact the electric heating wire 40. Without the need for an additional fixing device, the temperature measurement component 3 is fixed to the electric heating wire 40, thereby ensuring that the temperature measurement component 3 can better measure the temperature of the electric heating wire 40.

[0048] As Figure 4 and Figure 5 shown, the temperature measurement component 3 may include a positive electrode metal 310 and a negative electrode metal 320. Both the positive electrode metal 310 and the negative electrode metal 320 are strip-shaped metals; the first end of the positive electrode metal 310 is electrically connected to the positive electrode output terminal 1, and the first end of the negative electrode metal 320 is electrically connected to the negative electrode output terminal 2; there are multiple electrical connection points 33 formed between the second end of the positive electrode metal 310 and the second end of the negative electrode metal 320. The electrical connection points 33 divide the positive electrode metal 310 into multiple segments of the first positive electrode metal 31, and the electrical connection points 33 divide the negative electrode metal 320 into multiple segments of the first negative electrode metal 32.

[0049] It should be noted that in the present application, the long strip and the bar are used to describe that the length of the positive metal 310 and the negative metal 320 is greater than the cross-sectional size, and the cross-section of the positive metal 310 and the negative metal 320 can be circular or other shapes. In the present application, the positive metal 310 and the negative metal 320 can be a metal element or a metal alloy or a conductive metal oxide, and reference can be made to the positive and negative metal materials used in existing standard thermocouples.

[0050] Specifically, the positive electrode metal 310 and the negative electrode metal 320 may be contacted or welded to form an electrical connection point 33 , which will be described in detail below.

[0051] In some examples, such as Figure 4 As shown, the positive electrode metal 310 and the negative electrode metal 320 may form a plurality of contact points by contacting each other, and each contact point corresponds to an electrical connection point 33 .

[0052] For example, Figure 4 As shown, the positive metal 310 and the negative metal 320 are metal wires of different materials, and the positive metal 310 and the negative metal 320 are intertwined to form multiple contact points; and / or, the positive metal 310 and the negative metal 320 are both flexible metals. It can be seen that by adopting the winding contact method, multiple electrical connection points 33 can be formed between the positive metal 310 and the negative metal 320 without welding or external fixing structure, and the use of flexible metal can ensure that the temperature measuring component 3 can be bent and deformed and maintain the bent shape, so as to be wound or coiled around the outer periphery of the electric heating wire 40.

[0053] In some examples, such as Figure 5 As shown, the positive metal 310 and the negative metal 320 are metal wires of different materials, and multiple welding points are formed between the positive metal 310 and the negative metal 320 by welding, and each welding point corresponds to an electrical connection point 33; and / or, the positive metal 310 and the negative metal 320 are both flexible metals.

[0054] For example, by controlling the welding process, the volume of the welding point can actually be appropriately reduced. By using long strips of flexible metal to form multiple welding points, it is also possible to achieve Figure 3 The effect of winding around the outer periphery of the electric heating wire 40 is shown. Even if the welding points are still large, the distance between the welding points can be increased, and the temperature measuring component 3 can be wound around the outer periphery of the electric heating wire 40.

[0055] In practical applications, the material of the positive electrode metal 310 can be a nickel-chromium alloy, and / or the material of the negative electrode metal 320 can be a nickel-silicon alloy. Both can also use platinum-rhodium materials. The positive electrode metal 310 is strip-shaped, and the diameter of the positive electrode metal 310 can be 0.02 mm - 0.2 mm, and / or the negative electrode metal 320 is strip-shaped, and the diameter of the negative electrode metal 320 can be 0.02 mm - 0.2 mm. And / or, the resistance of each thermocouple structure 30 is the same. The specific lengths of the positive electrode metal 310 and the negative electrode metal 320 are not limited, with the aim of being able to wind around the outer periphery of the electric heating wire 40 after the two are wound or welded to form the temperature measuring component 3.

[0056] For example, when using the winding method as Figure 4 shown, the diameters of the positive electrode metal 310 and the negative electrode metal 320 can be 0.08 mm, the material of the positive electrode metal 310 can be nickel-chromium material, the material of the negative electrode metal 320 can be nickel-silicon material, and the number of winding turns between the two can be 4 - 9 turns. The diameter of the electric heating wire 40 can be 0.16 mm. At this time, the temperature measuring component 3 formed by winding can be bent and deformed and maintain the bent shape, and can maintain a state of being closely attached to the surface of the electric heating wire 40 after being wound around the electric heating wire 40, without the need to use other materials for fixation.

[0057] The welding point size of the existing welded probe is about 0.35 mm, while the diameter of the electric heating wire 40 is 0.16 mm. The welded thermocouple probe is in a point contact state with the electric heating wire 40. Without the help of other materials, it is difficult to maintain the fixed state between the welded thermocouple probe and the electric heating wire 40.

[0058] Since the size of the atomizing core is usually in the range of several millimeters, the atomizing core generally includes an electric heating wire 40 and a liquid guiding medium (such as fiber cotton). When atomizing, the temperature can reach above 300 °C. There are very large temperature changes in a very small space of the atomizing core. The closer to the surface of the electric heating wire 40, the higher the air flow temperature. Since the size of the temperature measuring component 3 of the temperature measuring device is smaller and it is in closer contact with the electric heating wire 40, compared with the standard thermocouple probe, the probe of the temperature measuring device is in a higher temperature air flow, and the measurement result will be closer to the temperature of the electric heating wire 40.

[0059] To compare the temperature measurement differences between the wound temperature measuring device (referred to as the wound thermocouple, where wound means that the temperature measuring component 3 is wound around the outer periphery of the electric heating wire 40) as Figure 4 or Figure 5 shown and the standard welded thermocouple, the two are respectively placed in the same indoor environment and the same water bath device (set temperature 75 °C) for temperature measurement. The measurement results are shown in Table 1 below:

[0060] Room temperature Water bath temperature Standard thermocouple 27.88℃ 73.78℃ Wound thermocouple 28.04℃ 73.98℃

[0061] It can be seen that the measurement result of the wound thermocouple is close to the temperature measurement result of the standard thermocouple, and the measurement result of the wound thermocouple is reliable.

[0062] In another test scenario, the wound temperature measurement device and the standard thermocouple are arranged on the same electric heating wire 40 for temperature measurement. The temperature measurement component 3 of the present application is arranged according to Figure 3 the setting shown on the outer periphery of the electric heating wire 40, and the actual temperatures of the measuring positions of the wound temperature measurement device and the standard thermocouple are respectively measured by a precise infrared thermal imager. The measurement results are shown in Table 2 below:

[0063] Standard thermocouple / 253℃ Wound thermocouple 267℃ / Infrared thermal imager 274℃ 276℃

[0064] It can be seen that the deviation between the measurement result of the wound thermocouple and the infrared measurement result is smaller than that of the standard thermocouple measurement result, which proves that the measurement result of the wound thermocouple is closer to the true temperature of the electric heating wire 40. Due to the heat transfer between the electric heating wire 40 and the temperature measurement component 3, there must be a temperature difference. The temperature difference measured by the temperature measurement device provided in the present application is smaller. As Figure 6 shown, for the primary heating test corresponding to Table 2, it can be seen that the measurement data of the wound thermocouple is continuous and can more accurately measure the temperature of the electric heating wire 40.

[0065] Embodiment 2:

[0066] As Figure 7 shown, the present embodiment provides a temperature measurement method applied to the temperature measurement device described in Embodiment 1. The temperature measurement method includes:

[0067] Step 1: Use the temperature measurement device to measure the temperature of the electric heating wire 40 of the electronic atomization device; wherein the temperature measurement points of the multiple thermocouple structures 30 of the temperature measurement device are in contact with the electric heating wire 40. Specifically, referring to Figure 3 the setting method shown, the temperature measurement component 3 is wound around the outer periphery of the electric heating wire 40.

[0068] Step 2: Obtain the first voltage between the positive output terminal 1 and the negative output terminal 2 of the temperature measurement device.

[0069] Step 3: Calculate the temperature of the electric heating wire 40 according to the first voltage. For example, regarding the corresponding relationship between the first voltage and the temperature, it can be through multiple-point temperature tests in advance to specify a table or curve between the first voltage and the temperature. Another example is that by using the same positive electrode metal 310 and negative electrode metal 320 as the standard thermocouple, the conversion calculation can be carried out according to the existing voltage-temperature relationship table of the standard thermocouple.

[0070] It can be seen that by using the above temperature measurement method, the temperature of the electric heating wire 40 can be measured more accurately, and based on this, the temperature of the electric heating wire 40 can be adjusted to improve the atomization effect of the electronic atomization device.

[0071] Embodiment 3:

[0072] As Figure 8 shown, this embodiment provides an electronic atomization device, which includes a liquid storage chamber 42, a liquid guiding medium 41, an atomization component, and the temperature measurement device described in Embodiment 1.

[0073] The liquid storage chamber 42 is used to store the atomization liquid. The liquid storage chamber 42 has a liquid guiding hole 43, and the atomization liquid penetrates into the liquid guiding medium 41 through the liquid guiding hole 43; the liquid guiding medium 41 is used to adsorb the atomization liquid; the atomization component is used to atomize the atomization liquid adsorbed by the liquid guiding medium 41; the temperature measurement device is used to measure the temperature of the atomization component. The present application does not limit the specific structure of the electronic atomization device, and any electronic atomization device whose atomization component uses an electric heating wire 40 can be used.

[0074] Among them, the atomization component includes an electric heating wire 40, and the temperature measurement component 3 of the temperature measurement device is wound around the outer periphery of the electric heating wire 40, and the temperature measurement points of the plurality of thermocouple structures 30 of the temperature measurement component 3 are in contact with the electric heating wire 40.

[0075] As described in Embodiment 1, by using the temperature measurement device of the present application, the temperature of the atomization core can be measured more accurately, which is beneficial to improving the control of the atomization effect and enhancing the user experience of using the electronic atomization device.

[0076] The above uses specific examples to elaborate on 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 technical field to which the present invention belongs, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
