Abstract
Description
Technical Field

[0002] Electronic atomizing devices are products that transform a liquid aerosol matrix into an aerosol through atomization 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.

However, the temperature of the aerosol at the mouthpiece cannot accurately represent the temperature of the aerosol in the user's mouth. Electronic atomizing devices adjusted based on the temperature of the aerosol at the mouthpiece pose a significant risk of harming the user's oral cavity, resulting in lower safety for electronic atomizing devices.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0027] Electronic atomizing devices are products that transform a liquid aerosol matrix into an aerosol through atomization 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. Excessively high aerosol temperatures can cause discomfort to the user's mouth and throat, and may also lead to minor burns or other injuries.
[0028] Before electronic atomizing devices are put into production, it is necessary to measure the temperature of the aerosol supplied by the device and adjust the device based on the measurement results to improve its safety. In related technologies, the method for testing aerosol temperature is to place a temperature sensing element on the mouthpiece and measure the temperature of the aerosol flowing from the mouthpiece. However, the temperature of the aerosol at the mouthpiece cannot accurately represent the temperature of the aerosol in the user's mouth. Electronic atomizing devices adjusted based on the temperature of the aerosol at the mouthpiece pose a significant risk of harming the user's oral cavity, resulting in lower safety for electronic atomizing devices.
[0029] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0030] Please refer to Figure 1 This application provides a measuring device, including an oral cavity simulation component, a temperature measuring component, a humidity control component, and a driving component.
[0031] The oral cavity simulation component has an aerosol flow channel, the inlet of which is connected to the outlet of an electronic atomizing device. A temperature measurement component is at least partially disposed within the aerosol flow channel, and is used to measure the temperature within the aerosol flow channel. A humidity control component is at least partially disposed within the aerosol flow channel, and is used to control the humidity within the aerosol flow channel. A drive component is connected to the outlet of the aerosol flow channel, and is used to drive the airflow from the inlet to the outlet.
[0032] In the measuring device provided in this application embodiment, the oral cavity simulation component can simulate the human oral cavity, and the humidity control component can control the humidity in the aerosol flow channel, so that the measuring device can more realistically simulate the human oral cavity and more accurately simulate the situation inside the human oral cavity when the user inhales the electronic atomizing device. In conjunction with the temperature measuring component, the temperature of the aerosol in the human oral cavity can be accurately measured; providing more accurate data for subsequent adjustment of the electronic atomizing device, thereby reducing the risk of the electronic atomizing device damaging the user's oral cavity and improving the safety of the electronic atomizing device.
[0033] When measuring the temperature of the aerosol using the measuring device of this embodiment, the humidity control component is adjusted to change the humidity within the aerosol channel, simulating the humidity inside the human mouth. The mouthpiece of the electronic atomizing device is inserted into the air inlet of the aerosol channel, and the drive component is activated, causing airflow from the air inlet to the air outlet of the aerosol channel. This allows the aerosol output from the electronic atomizing device to enter the aerosol channel and flow from the air inlet to the air outlet, accurately simulating the conditions inside the human mouth when a user inhales the electronic atomizing device. The temperature measuring component measures the temperature of the aerosol inside the mouth, indirectly measuring the temperature of the aerosol output from the electronic atomizing device within the human mouth, providing temperature data for subsequent adjustments to the electronic atomizing device.
[0034] It should be noted that the process of adjusting the electronic atomizing device can be as follows: The measuring device measures the temperature of the aerosol output by the electronic atomizing device at a certain setting in the human mouth. If the temperature is higher than the temperature that the human mouth can tolerate (e.g., 38 degrees Celsius), the electronic atomizing device is adjusted to lower the temperature of the aerosol output at the aforementioned setting; if the temperature is lower than the comfortable temperature for the human body (e.g., 30 degrees Celsius), the electronic atomizing device is adjusted to raise the temperature of the aerosol output at the aforementioned setting.
[0035] It should be noted that adjusting the electronic atomizer can be done by adjusting the power of the atomizer coil at each setting, thereby adjusting the temperature of the aerosol output by the electronic atomizer at each setting.
[0036] In some embodiments, the drive component includes an air pump for drawing airflow within the aerosol channel, such that the airflow flows from the inlet to the outlet.
[0037] Please refer to Figure 1 In some embodiments, the oral cavity simulation component includes a maxillary simulator 12, a mandibular simulator 13, and a tongue simulator 14. The maxillary simulator 12 and the mandibular simulator 13 enclose an aerosol channel, and the tongue simulator 14 is disposed within the aerosol channel.
[0038] The above settings can simulate the real structure inside the human oral cavity and accurately simulate the temperature changes of aerosols in the human oral cavity.
[0039] In some embodiments, the maxillary simulator 12 is constructed with realistic structures of the human maxilla, such as folds and upper dentition, and the mandibular simulator 13 is constructed with realistic structures of the human mandible, such as upper and lower dentition 131 (e.g., upper and lower dentition). Figure 2 As shown), the tongue simulator 14 is connected to the mandibular simulator 13.
[0040] The above settings enable the oral cavity simulation component to more realistically simulate the internal structure of the human oral cavity.
[0041] In some embodiments, the maxillary mannequin 12 and mandibular mannequin 13 are made of transparent material. This allows for easy observation of the internal structure of the oral cavity simulation components.
[0042] Please refer to Figure 1 In some embodiments, the temperature measurement assembly includes a first temperature sensing element 21 and a second temperature sensing element 22, the first temperature sensing element 21 being disposed on the maxillary simulator 12 and the second temperature sensing element 22 being disposed on the tongue simulator 14.
[0043] It should be noted that after the aerosol enters the human oral cavity, it mainly comes into contact with the maxilla and tongue. Therefore, the maxilla and tongue are quite sensitive to the temperature of the aerosol when inhaling from the electronic atomizing device. In this embodiment, by placing the first temperature sensing element 21 on the maxilla simulation element 12 and the second temperature sensing element 22 on the tongue simulation element 14, the temperature of the aerosol in contact with the maxilla simulation element 12 and the tongue simulation element can be measured, so as to accurately adjust the electronic atomizing device based on the measurement results.
[0044] Please refer to Figure 1 In some embodiments, multiple first temperature sensing elements 21 and multiple second temperature sensing elements 22 are provided, and the multiple first temperature sensing elements 21 and multiple second temperature sensing elements 22 are arranged at intervals along the airflow direction in the aerosol channel.
[0045] It should be noted that the temperature of the aerosol flowing within the aerosol channel varies; specifically, the temperature of the aerosol immediately upon entering the channel, the temperature of the aerosol in the middle of the channel, and the temperature at the outlet of the channel are different. This configuration in the above embodiment allows the temperature measurement component to detect the temperature of the aerosol at different locations, thereby improving measurement accuracy.
[0046] Please refer to Figure 1In some embodiments, three first temperature sensing elements 21 are provided, and in the direction of airflow in the aerosol channel, the three first temperature sensing elements 21 are respectively disposed at the front, middle and rear of the maxillary simulator 13.
[0047] Please refer to Figure 1 In some embodiments, three second temperature sensing elements 22 are provided, and the three second temperature sensing elements 22 are respectively disposed on the tip, middle and root of the tongue on the tongue simulator 14.
[0048] In some embodiments, the measuring device further includes an operating console, through which an operator changes the program parameters within the measuring device to adjust the preset humidity value within the aerosol flow channel. The operating console can be software installed on electronic devices such as mobile phones, tablets, and computers, and the operating platform can also be a touchscreen structure, button structure, or key structure set on the oral cavity simulation component.
[0049] When using the measuring device in the above embodiments to measure the temperature of aerosols, the operator can change the preset humidity value by changing the program parameters in the measuring device to change the humidity in the aerosol channel. The temperature in the aerosol channel can be measured under different humidity environments. Under the premise that only humidity is a variable, multiple sets of temperature data can be obtained, which is convenient for analyzing the relationship between the temperature in the aerosol channel and the humidity in the aerosol channel, so as to derive the rule of adjusting the electronic atomization device according to the humidity of the human oral cavity.
[0050] In some embodiments, the measuring device further includes a control component that automatically adjusts a humidity control component based on the humidity in the aerosol channel to maintain the humidity in the aerosol channel at a preset humidity value, so as to prevent the measurement accuracy from being affected by humidity changes and to ensure the consistency of humidity during the measurement process where humidity is a constant.
[0051] In some embodiments, the humidity control component includes a humidity monitoring element and a water supply element. The humidity monitoring element is disposed in the aerosol channel, and the water supply element is connected to the aerosol channel and is used to supply liquid into the aerosol channel.
[0052] With the above settings, the humidity monitoring element can monitor the humidity in the aerosol channel in real time. When the humidity in the aerosol channel is lower than the preset humidity, the control component controls the water supply component to supply liquid to the aerosol channel to increase the humidity in the aerosol channel. This keeps the humidity in the aerosol channel at the preset humidity value to prevent the measurement accuracy from being affected by humidity changes, thus ensuring the consistency of humidity in the measurement process where humidity is a constant.
[0053] Please refer to Figure 1In some embodiments, the maxillary simulator 12 is provided with a plurality of water spray holes 121, the two ends of which are connected to a water supply device and an aerosol channel, respectively.
[0054] By setting multiple water spray holes 121, the water replenishment positions can be dispersed, allowing the liquid to enter the aerosol channel more evenly, thereby maintaining the uniformity of humidity in the aerosol channel.
[0055] In some embodiments, the aperture of the spray hole 121 is less than 0.5 mm. This results in the droplets ejected from the spray hole 121 having a diameter of less than 0.5 mm, thereby dispersing the liquid within the aerosol channel and improving the uniformity of humidity within the aerosol channel.
[0056] Furthermore, when the test device of this application embodiment is used, the maxillary simulation component 12 is located above the mandibular simulation component 13. By opening the water spray hole 121 on the maxillary simulation component 12, the droplets sprayed from the water spray hole 121 can move downward under their own gravity, which helps the droplets to be evenly dispersed in the aerosol channel.
[0057] In some embodiments, the testing apparatus further includes a pressure sensing element disposed within the aerosol flow channel.
[0058] The user's suction speed affects the volume of aerosol entering the oral cavity per unit time, thus affecting the aerosol density and consequently the air pressure within the oral cavity. In other words, different suction speeds correspond to different air pressures within the oral cavity. In this embodiment, the driving component simulates the user's suction action by driving airflow within the aerosol channel. The speed of the airflow within the aerosol channel simulates the user's suction speed, and different airflow speeds result in different pressures within the aerosol channel.
[0059] This application embodiment monitors the pressure within the aerosol channel by setting a pressure sensing element, which can indirectly reflect the speed of airflow within the aerosol channel, thereby reflecting the corresponding suction speed. This facilitates the adjustment of the power of the drive component based on the data output by the pressure sensing element during measurement, thereby changing the speed of airflow within the aerosol channel. As a result, the drive component can more accurately simulate the user's suction action.
[0060] Please refer to Figure 1 In some embodiments, the aerosol flow channels include a lip flow channel 111, an oral flow channel 112, and a pharyngeal flow channel 113, and the temperature measurement assembly includes a third temperature sensing element 23 and a fourth temperature sensing element 24, with the third temperature sensing element 23 disposed in the lip flow channel 111 and the fourth temperature sensing element 24 disposed in the pharyngeal flow channel 113.
[0061] It should be noted that the lips and throat are also relatively sensitive structures in the human oral cavity. In this embodiment, by placing the third temperature sensing element 23 in the lip flow channel 111 and the fourth temperature sensing element 24 in the throat flow channel 113, the temperature of the aerosol in the lip flow channel 111 and the throat flow channel 113 can be measured, so as to accurately adjust the electronic atomization device according to the measurement results.
[0062] It should be noted that, in the embodiments of this application, the lip channel 111 is the air inlet in the aerosol channel, and the throat channel 113 is the air outlet in the aerosol channel.
[0063] Optionally, the first temperature sensing element 21, the second temperature sensing element 22, the third temperature sensing element 23 and the fourth temperature sensing element 24 can be resistance sensors or thermocouple sensors.
[0064] In some embodiments, the tongue simulator 14 is made of a plastic material.
[0065] It should be noted that the tongue in the human mouth can move flexibly, and the position and shape of the tongue affect the contact area between the tongue and the aerosol entering the oral cavity, as well as the movement speed and distribution of the aerosol within the mouth, thus affecting the temperature of the aerosol at different locations within the oral cavity. This embodiment of the application uses a plastic material to manufacture the tongue simulator 14, allowing the position and shape of the tongue simulator 14 to be changed, so that the tongue simulator 14 can more accurately simulate the tongue in different positions and shapes within the human oral cavity. This enables the measuring device to measure the temperature of the aerosol within the aerosol flow channel under the tongue simulator 14 at different positions and shapes.
[0066] In some embodiments, the maxillary simulator 12 and the mandibular simulator 13 are detachably connected. This facilitates adjustment of the position and shape of the tongue simulator 14, and also facilitates cleaning of the interior of the oral cavity simulator assembly.
[0067] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
