Description

Technical Field

[0001] This application relates to the field of measuring instrument technology, and more particularly to a measuring device. Background Technology

[0002] Electronic atomizing devices are products that atomize an aerosol-generating matrix into an aerosol through heating or other means. When a user inhales, the aerosol flows with the airflow generated by the user's inhalation and enters the user's mouth. Excessive aerosol temperature, flow rate, or pressure can cause discomfort to the user's mouth and throat, resulting in a poor user experience.

[0003] Before electronic atomization devices are put into production, it is necessary to measure the inhalation experience (temperature, aerosol flow rate, or pressure, etc.) and adjust the draw resistance or the power of the atomizer coil based on the measurement results to ensure a good user experience. In related technologies, the method of measuring the inhalation experience of an electronic atomization device involves placing a sensing element (temperature sensor, airflow velocity sensor, or pressure sensor) at the inhalation port to measure the temperature and pressure of the aerosol flowing out of the port. However, this measurement method has many limitations, such as large data fluctuations, poor repeatability, and inconsistencies between the smoke temperature data and human sensory temperature. Therefore, it cannot accurately reflect the inhalation experience of the electronic atomization device. Adjusting the draw resistance or the power of the atomizer coil based on the temperature and pressure of the aerosol at the inhalation port will result in a poor user experience. Utility Model Content

[0004] The purpose of this application is to provide a measuring device that improves the measurement accuracy of the inhalation sensation of an electronic atomizing device.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: a measuring device disposed between an electronic atomizing device and a suction device, used to measure the suction sensation of the electronic atomizing device, the measuring device including a main body component and a measuring component.

[0006] The main component has an airflow channel, which includes an air intake section and a measuring chamber connected in sequence. The end of the air intake section away from the measuring chamber is connected to the suction port of the electronic atomizing device, and the end of the measuring chamber away from the air intake section is connected to the suction device. The measuring component is housed in the measuring chamber. The radial cross-sectional area of ​​the measuring chamber is larger than the radial cross-sectional area of ​​the air intake section.

[0007] The beneficial effects of the measuring device provided in this application are as follows: Since the end of the air inlet section away from the measuring chamber is connected to the suction port of the electronic atomizing device, and the end of the measuring chamber away from the air inlet section is connected to the suction device, the flow direction of the aerosol in the measuring device when measuring the suction sensation of the electronic atomizing device is air inlet section → measuring chamber. Because the radial cross-sectional area of ​​the measuring chamber is larger than that of the air inlet section, the radial cross-sectional area of ​​the airflow channel suddenly increases at the connection between the air inlet section and the measuring chamber, forming a sudden expansion structure at the connection. When the aerosol flows from the air inlet section into the measuring chamber, the sudden expansion structure can rapidly reduce the aerosol flow velocity, acting as a buffer to reduce the impact of the aerosol on the measuring components, thereby reducing the impact on the measurement accuracy of the measuring components and improving the measurement accuracy of the suction sensation of the electronic atomizing device.

[0008] In some embodiments, the airflow passage further includes:

[0009] The air outlet section has one end connected to the end of the measuring cavity away from the air inlet section, and the end of the air outlet section away from the measuring cavity is connected to the suction device.

[0010] In some embodiments, the measuring chamber includes a communicating expansion section and a recirculation section, the expansion section being connected to the air inlet section and the recirculation section being connected to the air outlet section; the measuring component is disposed between the expansion section and the recirculation section.

[0011] In some embodiments, in the extending direction of the airflow channel, the length of the recirculation section is 8 / 3 to 4 times the length of the expansion section.

[0012] In some embodiments, the measuring component includes a bracket and a sensor, the bracket being housed within the measuring cavity and connected to the main body component, the sensor being disposed on the bracket and corresponding to the air intake section.

[0013] In some embodiments, the support includes a plurality of crossbeams spaced radially in the airflow channel, and each crossbeam has at least one of the sensors.

[0014] In some embodiments, the sensing element includes at least one of a temperature sensor, an airflow velocity sensor, and a pressure sensor.

[0017] The first end plate includes a first connecting part and an air inlet cylinder. The first connecting part is connected to the base and covers one end opening of the U-shaped groove along its length.

[0018] A cover plate, connected to the base and / or the first end plate, and the cover plate covers the opening in the depth direction of the U-shaped groove; wherein,

[0019] The base plate, the first side plate, the second side plate, the first connecting part, and the cover plate enclose the measuring cavity, and the air inlet cylinder communicates with the measuring cavity, forming at least a portion of the air inlet section.

[0035] For ease of understanding, the attached diagram shows the mutually orthogonal X-axis and Y-axis. The direction along the X-axis is called the X-direction, and the direction along the Y-axis is called the Y-direction.

[0036] Electronic atomizing devices are products that atomize an aerosol-generating matrix into an aerosol through heating or other means. When a user inhales, the aerosol flows with the airflow generated by the user's inhalation and enters the user's mouth. Excessive aerosol temperature, flow rate, or pressure can cause discomfort to the user's mouth and throat, resulting in a poor user experience.

[0037] Before electronic atomization devices are put into production, it is necessary to measure the inhalation experience (temperature, aerosol flow rate, or pressure, etc.) and adjust the draw resistance or the power of the atomizer coil based on the measurement results to ensure a good user experience. In related technologies, the method of measuring the inhalation experience of an electronic atomization device involves placing a sensing element (temperature sensor, airflow velocity sensor, or pressure sensor) at the inhalation port to measure the temperature and pressure of the aerosol flowing out of the port. However, this measurement method has many limitations, such as large data fluctuations, poor repeatability, and inconsistencies between the smoke temperature data and human sensory temperature. Therefore, it cannot accurately reflect the inhalation experience of the electronic atomization device. Adjusting the draw resistance or the power of the atomizer coil based on the temperature and pressure of the aerosol at the inhalation port will result in a poor user experience.

[0038] In view of the above problems, this application provides a measuring device to improve the measurement accuracy of the inhalation sensation of an electronic atomizing device.

[0039] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0040] Please refer to Figures 1 to 4 This application provides a measuring device disposed between an electronic atomizing device and a suction device for measuring the suction sensation of the electronic atomizing device. The measuring device includes a main body component 1 and a measuring component 2.

[0041] The main component 1 has an airflow channel 11, which includes an air inlet section 111 and a measuring chamber 112 connected in sequence. The end of the air inlet section 111 away from the measuring chamber 112 is connected to the suction port of the electronic atomizing device, and the end of the measuring chamber 112 away from the air inlet section 111 is connected to the suction device. The measuring component 2 is housed within the measuring chamber 112. The radial cross-sectional area of ​​the measuring chamber 112 is larger than the radial cross-sectional area of ​​the air inlet section 111.

[0042] Please refer to Figure 3 It should be noted that, for ease of understanding, the intake section 111 and the measuring chamber 112 are separated by dashed lines in the figure.

[0043] It should be noted that the suction device can be, but is not limited to, a smoke extractor or a vacuum pump.

[0044] It should be noted that the inhalation sensation of an electronic atomizing device refers to the user's perception of the temperature, flow rate, or pressure of the aerosol entering the user's mouth when inhaling the electronic atomizing device. In this embodiment, the measuring component 2 corresponds to the human oral cavity, and the temperature, flow rate, or pressure of the aerosol within the measuring cavity 112 can reflect the temperature, flow rate, or pressure of the aerosol in the user's oral cavity. Therefore, the measuring device in this embodiment can measure the inhalation sensation of an electronic atomizing device.

[0045] It should be noted that the measurement component 2 is used to measure the temperature, flow rate, or pressure of the aerosol within the measurement chamber 112, depending on the type of sensor included in the measurement component 2. For example, if the measurement component 2 includes a temperature sensor, it can measure the temperature of the aerosol within the measurement chamber 112. If the measurement component 2 includes an airflow velocity sensor, it can measure the flow rate of the aerosol within the measurement chamber 112. If the measurement component 2 includes a pressure sensor, it can measure the pressure of the aerosol within the measurement chamber 112.

[0046] It should be noted that the radial section of the airflow channel 11 is the section perpendicular to the flow direction of the aerosol within the airflow channel 11, the radial section of the measuring chamber 112 is the section perpendicular to the flow direction of the aerosol within the measuring chamber 112, and the radial section of the air inlet section 111 is the section perpendicular to the flow direction of the aerosol within the measuring chamber 112.

[0047] Generally, the shapes of the measuring chamber 112 and the air inlet section 111 are regular to facilitate the fabrication of the measuring device; that is, the air inlet section 111 is a cylindrical or prismatic channel, and the measuring chamber 112 is cylindrical or prismatic. When using the measuring device to measure the inhalation sensation of an electronic atomizing device, the flow direction of the aerosol in the air inlet section 111 is a first straight line, and the radial section of the air inlet section 111 is perpendicular to the first straight line; the flow direction of the aerosol in the measuring chamber 112 is a second straight line, and the radial section of the measuring chamber 112 is perpendicular to the second straight line. For example, refer to... Figure 1 and Figure 2The intake section 111 is cylindrical, and the measuring cavity 112 is quadrangular. The central axis of the intake section 111 and the central axis of the measuring cavity 112 coincide, and both the central axis of the intake section 111 and the central axis of the measuring cavity 112 are parallel to the X direction in the figure. The flow direction of the aerosol in the intake section 111 coincides with the flow direction of the aerosol in the measuring cavity 112. That is, the first straight line and the second straight line mentioned above coincide and are parallel to the X direction in the figure. The radial cross section of the airflow channel 11, the radial cross section of the measuring cavity 112, and the radial cross section of the intake section 111 are all parallel to the Y direction in the figure.

[0048] Of course, the shapes of the intake section 111 and the measuring chamber 112 can both be irregular shapes, that is, the flow direction of the aerosol in the intake section 111 is an irregular line, and the flow direction of the aerosol in the measuring chamber 112 is an irregular line. Then, the radial cross-section of the measuring chamber 112 being greater than the radial cross-sectional area of ​​the intake section 111 means that, at least at the connection between the measuring chamber 112 and the intake section 111, the cross-section of the measuring chamber 112 perpendicular to the aerosol flow direction of the measuring chamber 112 is greater than the cross-section of the intake section 111 perpendicular to the aerosol flow direction of the intake section 111.

[0049] It should be noted that in the measuring device of this embodiment, the end of the air inlet section 111 away from the measuring chamber 112 is used to communicate with the suction port of the electronic atomizing device, and the end of the measuring chamber 112 away from the air inlet section 111 is used to communicate with the suction device. Therefore, when measuring the suction sensation of the electronic atomizing device, the flow direction of the aerosol in the measuring device is air inlet section 111 → measuring chamber 112. Since the radial cross-sectional area of ​​the measuring chamber 112 is larger than that of the air inlet section 111, the radial cross-sectional area of ​​the airflow channel 11 suddenly increases at the connection between the air inlet section 111 and the measuring chamber 112, forming a sudden expansion structure at the connection between the air inlet section 111 and the measuring chamber 112. When the aerosol flows from the air inlet section 111 into the measuring chamber 112, the sudden expansion structure can rapidly reduce the flow rate of the aerosol, playing a buffering role to reduce the impact of the aerosol on the measuring component 2, thereby reducing the impact on the measurement accuracy of the measuring component 2, and thus improving the measurement accuracy of the suction sensation of the electronic atomizing device.

[0050] It should be noted that the shape and direction of the aerosol flow column will vary depending on the design of the atomizer core, airway, and inhalation port in the electronic atomizing device. In the measuring device of this embodiment, the aerosol from the electronic atomizing device first diffuses within the air inlet section 111. The air inlet section 111 can uniformly quantify the aerosol, ensuring that the aerosol entering the air inlet section 111 conforms to its shape. This maintains a uniform shape for the aerosol entering the measuring chamber 112, thus strictly controlling irrelevant variables during the measurement process. This reduces the impact of irrelevant variables such as the atomizer core design, airway design, and inhalation port design on the measurement results, thereby improving the measurement accuracy of the inhalation sensation of the electronic atomizing device using the measuring device of this embodiment.

[0051] It should be noted that in the measuring device of this application embodiment, the air inlet section 111 uniformly quantifies the aerosol, so that the shape of the aerosol entering the measuring chamber 112 remains uniform. This allows for consistent or highly similar measurement results when measuring the inhalation sensation of the same electronic atomizing device multiple times, thereby improving the repeatability of the measurement process. As a result, more data can be obtained through multiple measurements, which is convenient for subsequent statistical analysis to obtain more accurate measurement results.

[0052] It should be noted that the length of the intake section 111 in the extension direction of the airflow channel 11 is closely related to the area of ​​the air intake port of the intake section 111. Please refer to... Figures 1 to 4 In one embodiment, the intake section 111 is cylindrical in shape, the intake port of the intake section 111 is circular, the radius of the intake port of the intake section 111 is R, and the length L1 of the intake section 111 is the length in the X direction in the figure, L1=2R~4R.

[0053] Please refer to Figure 3 and Figure 4 In some embodiments, the airflow channel 11 further includes an air outlet section 113 (for ease of understanding, the air outlet section 113 and the measuring chamber 112 are separated by dashed lines in the figure). One end of the air outlet section 113 is connected to the end of the measuring chamber 112 away from the air inlet section 111, and the end of the air outlet section 113 away from the measuring chamber 112 is connected to the suction device. The radial cross-sectional area of ​​the air outlet section 113 is smaller than the radial cross-sectional area of ​​the measuring chamber 112.

[0054] It should be noted that in the above embodiment, one end of the outlet section 113 is connected to the end of the measuring chamber 112 away from the inlet section 111, and the end of the outlet section 113 away from the measuring chamber 112 is connected to the suction device. Therefore, when measuring the suction sensation of the electronic atomizing device, the flow direction of the aerosol in the measuring device is inlet section 111 → measuring chamber 112 → outlet section 113. Since the radial cross-sectional area of ​​the outlet section 113 is smaller than that of the measuring chamber 112, the radial cross-sectional area of ​​the airflow channel 11 suddenly decreases at the connection between the measuring chamber 112 and the outlet section 113, forming a constriction structure at the connection between the measuring chamber 112 and the outlet section 113. When the aerosol flows from the measuring chamber 112 into the outlet section 113, the constriction structure can introduce local resistance, causing the aerosol to need to overcome a larger pressure difference when passing through the connection between the measuring chamber 112 and the outlet section 113, thus slowing down the flow rate of the aerosol.

[0055] In the measuring device of this application embodiment, the flow velocity of the aerosol passing through the measuring component 2 needs to be controlled within a certain range to reduce the impact of the aerosol on the measuring component 2. In the above embodiment, by setting an outlet section 113, and the radial cross-sectional area of ​​the outlet section 113 is smaller than the radial cross-sectional area of ​​the measuring cavity 112, a constriction structure is formed at the connection between the measuring cavity 112 and the outlet section 113, which can slow down the flow velocity of the aerosol, thereby reducing the impact of the aerosol on the measuring component 2 and improving the measurement accuracy of the inhalation sensation of the electronic atomizing device.

[0056] It should be noted that the aerosol flow rate can be adjusted by changing the length of the outlet section 113. Specifically, the longer the outlet section 113, the lower the aerosol velocity.

[0057] Please refer to Figures 1 to 4 In some embodiments, the air intake section 111 is cylindrical in shape, the air intake port of the air intake section 111 is circular, the radius of the air intake port of the air intake section 111 is R, and the length L2 of the air outlet section 113 is the length in the X direction in the figure, where L2≤8R.

[0058] It should be noted that the radial section of the exhaust section 113 is the section of the exhaust section 113 perpendicular to the flow direction of the aerosol within the exhaust section 113.

[0059] Generally, the shape of the outlet section 113 is regular to facilitate the preparation of the measuring device; that is, the outlet section 113 is a cylindrical or prismatic channel. When measuring the inhalation sensation of an electronic atomizing device using the measuring device, the flow direction of the aerosol within the outlet section 113 is the third straight line, and the radial section of the outlet section 113 is perpendicular to the third straight line. For example, refer to... Figure 1 and Figure 2The exhaust section 113 is cylindrical in shape, and its central axis is parallel to the X direction in the figure. The central axis of the exhaust section 113, the central axis of the intake section 111, and the central axis of the measuring chamber 112 coincide. The flow direction of the aerosol in the exhaust section 113 coincides with the flow direction of the aerosol in the measuring chamber 112. That is, the first straight line, the second straight line, and the third straight line coincide and are parallel to the X direction in the figure. The radial section of the exhaust section 113 is parallel to the Y direction in the figure.

[0060] Of course, the shape of the outlet section 113 can also be irregular, that is, the flow direction of the aerosol in the outlet section 113 is an irregular line. Then, the radial cross-sectional area of ​​the outlet section 113 being smaller than the radial cross-sectional area of ​​the measuring cavity 112 means that, at least at the connection between the measuring cavity 112 and the outlet section 113, the cross-section of the outlet section 113 perpendicular to the aerosol flow direction of the outlet section 113 is smaller than the cross-section of the measuring cavity 112 perpendicular to the aerosol flow direction of the measuring cavity 112.

[0061] Please refer to Figure 3 In some embodiments, the measuring chamber 112 includes a communicating expansion section 1121 and a return section 1122 (the expansion section 1121 and the return section 1122 are separated by dashed lines in the figure for ease of understanding). The expansion section 1121 is connected to the intake section 111, and the return section 1122 is connected to the outlet section 113. The measuring component 2 is disposed between the expansion section 1121 and the return section 1122.

[0062] It should be noted that, since the radial cross-sectional area of ​​the exhaust section 113 is smaller than that of the measuring cavity 112, local resistance is introduced at the connection between the exhaust section 113 and the measuring cavity 112, leading to aerosol backflow. This aerosol backflow causes uneven aerosol flow velocity around the measuring component 2, thus affecting its measurement accuracy. In the above embodiment, by designing a backflow section 1122 of a certain length, the backflowing aerosol can be prevented from affecting the measurement accuracy of the measuring component 2.

[0063] Please refer to Figures 1 to 4 In some embodiments, the intake section 111 is cylindrical in shape, the intake port of the intake section 111 is circular, the radius of the intake port of the intake section 111 is R, and the length L3 of the return section 1122 is the length in the X direction in the figure, where L3≥4R.

[0064] Optionally, the shape of the reflux section 1122 may include, but is not limited to, prism or cylinder.

[0065] Please refer to Figures 1 to 4In some embodiments, the intake section 111 is cylindrical in shape, the intake port of the intake section 111 is circular, the radius of the intake port of the intake section 111 is R, and the length L4 of the return section 1122 is the length in the X direction in the figure, which should satisfy L4=1R~1.5R.

[0066] Optionally, the shape of the expansion segment 1121 includes, but is not limited to, prism or cylinder.

[0067] In some embodiments, the length of the recirculation section 1122 in the extending direction of the airflow channel 11 (X direction in the figure) is 8 / 3 to 4 times the length of the expansion section 1121.

[0068] It should be noted that the longer the reflux section 1122 is, the smaller the impact of the refluxed aerosol on the measuring component 2; however, the longer the reflux section 1122 is, the larger the volume of the measuring device. The above embodiment, by limiting the length of the reflux section 1122 to 8 / 3 to 4 times the length of the expansion section 1121, can both ensure that the impact of the refluxed aerosol on the measuring component 2 is small and minimize the volume of the measuring device.

[0069] Please refer to Figure 2 In some embodiments, the measuring component 2 includes a bracket 21 and a sensor 22. The bracket 21 is housed in the measuring cavity 112 and is connected to the main component 1. The sensor 22 is disposed on the bracket 21 and corresponds to the air intake section 111.

[0070] In some embodiments, the sensing element 22 includes at least one of a temperature sensor, an airflow velocity sensor, and a pressure sensor.

[0071] The sensor can be selected according to the measurement requirements. For example, if the temperature of the aerosol flowing out of the electronic atomizing device is to be measured, the sensing element 22 includes a temperature sensor; if the flow rate of the aerosol flowing out of the electronic atomizing device is to be measured, the sensing element 22 includes an airflow velocity sensor; if the pressure of the aerosol flowing out of the electronic atomizing device is to be measured, the sensing element 22 includes a pressure sensor; if the temperature and flow rate of the aerosol flowing out of the electronic atomizing device are to be measured, the sensing element 22 includes a temperature sensor and an airflow velocity sensor; if the temperature, flow rate, and pressure of the aerosol flowing out of the electronic atomizing device are to be measured, the sensing element 22 includes a temperature sensor, an airflow velocity sensor, and a pressure sensor.

[0072] Among them, the temperature sensor can be, but is not limited to, a thermocouple, a resistance temperature detector (RTD), or an infrared temperature sensor; the airflow velocity sensor can be, but is not limited to, a thermal airflow sensor, a differential pressure airflow sensor, or a thermal film airflow sensor; and the pressure sensor can be, but is not limited to, a strain gauge pressure sensor, a piezoresistive pressure sensor, or a capacitive pressure sensor.

[0073] Please refer to Figure 2 In some embodiments, the support 21 includes a plurality of crossbeams 211, which are arranged radially spaced in the airflow channel 11, and each crossbeam 211 has at least one sensing element 22.

[0074] It should be noted that at the location of the abrupt expansion structure, the aerosol undergoes decompression and expansion, leading to the gradual separation of the high-temperature region, transition region, and low-temperature region within the aerosol. The separation effect is as follows: Figure 5 As shown, the separated high-temperature zone, transition zone, and low-temperature zone are roughly distributed radially away from the central axis of the airflow channel 11. In the above embodiment, by setting multiple crossbeams 211, which are spaced apart radially in the airflow channel 11, and each crossbeam 211 has at least one sensing element 22, the measuring component 2 can measure the temperature, flow rate, pressure, etc. of the aerosol as a whole.

[0075] Please refer to Figure 1 and Figure 2 In some embodiments, the main component 1 includes a base 12, a first end plate 13, and a cover plate 14. The base 12 includes a bottom plate 121, a first side plate 122, and a second side plate 123. The first side plate 122 and the second side plate 123 are respectively connected to opposite ends of the bottom plate 121, and the first side plate 122, the bottom plate 121, and the second side plate 123 form a U-shaped groove. The first end plate 13 includes a first connecting portion 131 and an air inlet 132. The first connecting portion 131 is connected to the base 12 and covers one end opening in the length direction of the U-shaped groove. The cover plate 14 is connected to both the base 12 and / or the first end plate 13, and the cover plate 14 covers the opening in the depth direction of the U-shaped groove. The base plate 121, the first side plate 122, the second side plate 123, the first connecting part 131 and the cover plate 14 enclose and form a measuring cavity 112.
